The activities of the life sciences are essential to provide solutions for the future, for both individuals and society. Society has demanded growing accountability from the scientific community as implications of life science research rise in influence and there are concerns about the credibility, integrity and motives of science. While the scientific community has responded to concerns about its integrity in part by initiating training in research integrity and the responsible conduct of research, this approach is minimal. The scientific (...) community justifies itself by appealing to the ethos of science, claiming academic freedom, self-direction, and self-regulation, but no comprehensive codification of this foundational ethos has been forthcoming. A review of the professional norms of science and a prototype code of ethics for the life sciences provide a framework to spur discussions within the scientific community to define scientific professionalism. A formalization of implicit principles can provide guidance for recognizing divergence from the norms, place these norms within a context that would enhance education of trainees, and provide a framework for discussing externally and internally applied pressures that are influencing the practice of science. The prototype code articulates the goal for life sciences research and the responsibilities associated with the freedom of exploration, the principles for the practice of science, and the virtues of the scientists themselves. The time is ripe for scientific communities to reinvigorate professionalism and define the basis of their social contract. Codifying the basis of the social contract between science and society will sustain public trust in the scientific enterprise. (shrink)

In computer science, an algorithm is an unambiguous specification of how to solve a class of problems. Algorithms can perform calculation, data processing and automated reasoning tasks. As an effective method, an algorithm can be expressed within a finite amount of space and time and in a well-defined formal language for calculating a function. Starting from an initial state and initial input (perhaps empty), the instructions describe a computation that, when executed, proceeds through a finite number of well-defined successive states, (...) eventually producing "output" and terminating at a final ending state. The transition from one state to the next is not necessarily deterministic; some algorithms, known as randomized algorithms, incorporate random input. This book introduces a set of concepts in solving problems computationally such as Growth of Functions; Backtracking; Divide and Conquer; Greedy Algorithms; Dynamic Programming; Elementary Graph Algorithms; Minimal Spanning Tree; Single-Source Shortest Paths; All Pairs Shortest Paths; Flow Networks; Polynomial Multiplication, to ways of solving NP-Complete Problems, supported with comprehensive, and detailed problems and solutions, making it an ideal resource to those studying computer science, computer engineering and information technology.

When a group does harm, sometimes there’s no obvious individual who bears moral responsibility, and yet we still intuit that someone is to blame. This apparent ‘deficit’ of moral responsibility has led some scholars to posit that groups themselves can be responsible, and that this responsibility is distributed in some uniform fashion among group members. This solution to the deficit, however, risks providing a scapegoat for individuals who have acted wrongly and shifting blame onto those who have not. Instead, (...) this article argues that, in most deficit cases, moral responsibility is borne not by the group but by specific individual members. When an individual acts within a group, she gains an increased potential for doing harm – and, accordingly, heightened duties of care toward others. These duties can, depending on the individual’s position, require amending the group’s rules, procedures, and norms. In most deficit cases, it is individuals who have failed to fulfill these duties who are responsible. (shrink)

Berkeley's philosophy is meant to be a defense of commonsense. However, Berkeley's claim that the ultimate constituents of physical reality are fleeting, causally passive ideas appears to be radically at odds with commonsense. In particular, such a theory seems unable to account for the robust structure which commonsense (and Newtonian physics) takes the world to exhibit. The problem of structure, as I understand it, includes the problem of how qualities can be grouped by their co-occurrence in a single enduring (...) object and how these enduring objects can bear spatiotemporal, causal, and other relations to one another. I argue that Berkeley's solution to these problems lies in his views about language. At one level, human language allows us to exploit patterns in our perceptions to construct a highly structured representation of the physical world which allows us to make accurate predictions at minimal cognitive expense. At a deeper level, these patterns occur in perception because our perceptions themselves form a language in which God speaks to us. (shrink)

Cosmopolitanism seems to appeal to liberal neutrality because both are committed to core values such as reciprocity, autonomy, respect for the individual, personal accountability, and inclusivity. Further, cosmopolitanism is legitimate for many only insofar as it endorses value-pluralism in open societies, which is a staple of liberal neutrality. And yet, one might think that there is a moral obligation to create a cosmopolitan community. One can think of this as moral (normative) cosmopolitanism. To the end of creating a cosmopolitan community, (...) certain values ought to be fostered in laws and public policies, and certain attitudes ought to be cultivated. This leads to a potential impasse, namely if cosmopolitanism is committed to neutrality then it cannot promote its normativity, and if it is not committed to neutrality then it cannot promote value-pluralism. I propose a solution to this potential impasse by examining several of the democratic and cosmopolitan commitments of Alain Locke. What I take from Locke is his grounding of both pluralism and moral cosmopolitanism in democratic, time-honored principles that exist in all acts of free association, namely: liberty, equality, and fraternity. These values, of necessity, pervade all political conceptions of good lives because all political conceptions require what acts of free association allow, namely community with others. To this end, I provide an argument for how someone can consistently be committed to both moral cosmopolitanism and liberal neutrality. (shrink)

In this paper I argue against what I call ‘strict evidentialism’, the view that evidence is the sole factor for determining the normative status of beliefs. I argue that strict evidentialism fails to capture the uniquely subjective standpoint of believers and as a result it fails to provide us with the tools necessary to apply its own epistemic norms. In its place I develop an interest-relative theory of justification which I call quasi-evidentialism, according to which S has a justified (...) belief that P at time t if and only if S’s evidence at time t supports P in proportion to S’s interest in P. I take interests as fixed and argue that adjusting our confidence in a proposition in the right way, given our interests, is fine-tuned through the exercise of intellectual virtue, in particular the virtue of epistemic conscientiousness. This theory refocuses epistemic responsibility in the subject and by locating agency in the cultivation of epistemic virtue it also provides a handy solution to the problem of doxastic voluntarism, insofar as the development of our epistemic virtue guides our responsiveness to reason.

Concerns about the risks of unmitigated greenhouse gas emissions are growing. At the same time, confidence that international policy agreements will succeed in considerably lowering anthropogenic greenhouse gas emissions is declining. Perhaps as a result, various geoengineering solutions are gaining attention and credibility as a way to manage climate change. Serious consideration is currently being given to proposals to cool the planet through solar-radiation management. Here we analyze how the unique and nontrivial risks of geoengineering strategies pose fundamental questions at (...) the interface between science and ethics. To illustrate the importance of integrated ethical and scientific analysis, we define key open questions and outline a coupled scientific-ethical research agenda to analyze solar-radiation management geoengineering proposals. We identify nine key fields of coupled research including whether solar-radiation management can be tested, how quickly learning could occur, normative decisions embedded in how different climate trajectories are valued, and justice issues regarding distribution of the harms and benefits of geoengineering. To ensure that ethical analyses are coupled with scientific analyses of this form of geoengineering, we advocate that funding agencies recognize the essential nature of this coupled research by establishing an Ethical, Legal, and Social Implications program for solar-radiation management.

The target article “Thinking Through Other Minds” (TTOM) offered an account of the distinctively human capacity to acquire cultural knowledge, norms, and practices. To this end, we leveraged recent ideas from theoretical neurobiology to understand the human mind in social and cultural contexts. Our aim was bothsynthetic– building an integrative model adequate to account for key features of cultural learning and adaptation; andprescriptive– showing how the tools developed to explain brain dynamics can be applied to the emergence of social and (...) cultural ecologies of mind. In this reply to commentators, we address key issues, including: (1) refining the concept of culture to show how TTOM and the free-energy principle (FEP) can capture essential elements of human adaptation and functioning; (2) addressing cognition as an embodied, enactive, affective process involving cultural affordances; (3) clarifying the significance of the FEP formalism related to entropy minimization, Bayesian inference, Markov blankets, and enactivist views; (4) developing empirical tests and applications of the TTOM model; (5) incorporating cultural diversity and context at the level of intra-cultural variation, individual differences, and the transition to digital niches; and (6) considering some implications for psychiatry. The commentators’ critiques and suggestions point to useful refinements and applications of the model. In ongoing collaborations, we are exploring how to augment the theory with affective valence, take into account individual differences and historicity, and apply the model to specific domains including epistemic bias.

In this paper I characterize science in terms of both invisible hand social organization and selection. These two processes are responsible for different features of science. Individuals working in isolation cannot produce much in the way of the warranted knowledge. Individual biases severely limit how much secure knowledge an individual can generate on his or her own. Individuals working in consort are required, but social groups can be organized in many different ways. The key feature of the social organization in (...) science is that only working scientists can confer the most important reward in science — use — and scientists must use each other's work in order to succeed in realizing this goal. An analysis of science as a selection process serves quite a different function. Individual scientists strive to come up with novel solutions to significant problems. The question then becomes how to be creative. From a selective perspective, science as a process involves the production of numerous alternatives and a selection among them. A single scientist solving an important problem makes science look very efficient. Treating science as a selection process casts it in a very different light. In this paper I combine an invisible hand mechanism with a selective perspective in order to explain why science is as successful as it is. I do not make recourse to evolutionary epistemology in any of its traditional senses. (shrink)

Philosophy & Social Criticism, Volume 48, Issue 5, Page 655-673, June 2022. The standard account of the relation between democracy and the rule of law focuses on law’s liberty-enhancing role in constraining official action. This is a faint echo of the complex, constitutive relation between the two. The Greeks used one word – isonomia – to describe both. If democracy is the system in which people have an equal say in determining the rules that govern social life, then the rule (...) of law is simultaneously before, after, concurrent and synonymous with democracy: It contributes to the formation of citizens with the capacity for self-governance, serves as the instrument through which democratic decisions are implemented, functions as one of the central social practices that constitute citizens as equals and addresses the question of how to ensure that government by the people operates for the people. The rule of law has many independently valuable qualities, including impartiality and predictability. But, to valorise the rule of law for its own sake is to fetishize authority. The fundamental values of the rule of law are as the instrument of democratic self-governance and the expression of the equal dignity of all persons. Democracy thus entails the rule of law, but both implicate the yet more comprehensive ideal of equality. Core rule-of-law values require political norms and conditions of equality, generality and comprehensiveness. In a modern, differentiated society, however, the constitutive relation between democracy and the rule of law is fractured and law becomes the agent of authority. Courts in the modern constitutional state have contributed to the decline of rule-of-law values, supporting role specialization through judge-made immunity doctrines that protect officials at all levels. The crisis of police violence against minorities is a symptom of this breakdown. Greater accountability can ameliorate the problem. But an effective solution requires the fair and equal distribution of political power. (shrink)

BackgroundGene drive technologies (GDTs) promote the rapid spread of a particular genetic element within a population of non-human organisms. Potential applications of GDTs include the control of insect vectors, invasive species and agricultural pests. Whether, and if so, under what conditions, GDTs should be deployed is hotly debated. Although broad stances in this debate have been described, the convictions that inform the moral views of the experts shaping these technologies and related policies have not been examined in depth in the (...) academic literature.MethodsIn this qualitative study, we interviewed GDT experts (n = 33) from different disciplines to identify and better understand their moral views regarding these technologies. The pseudonymized transcripts were analyzed thematically.ResultsThe respondents’ moral views were principally influenced by their attitudes towards (1) the uncertainty related to GDTs; (2) the alternatives to which they should be compared; and (3) the role humans should have in nature. Respondents agreed there is epistemic uncertainty related to GDTs, identified similar knowledge gaps, and stressed the importance of realistic expectations in discussions on GDTs. They disagreed about whether uncertainty provides a rationale to refrain from field trials (‘risks of intervention’ stance) or to proceed with phased testing to obtain more knowledge given the harms of the status quo (‘risks of non-intervention’ stance). With regards to alternatives to tackle vector-borne diseases, invasive species and agricultural pests, respondents disagreed about which alternatives should be considered (un)feasible and (in)sufficiently explored: conventional strategies (‘downstream solutions’ stance) or systematic changes to health care, political and agricultural systems (‘upstream solutions’ stance). Finally, respondents held different views on nature and whether the use of GDTs is compatible with humans’ role in nature (‘interference’ stance) or not (‘non-interference stance’).ConclusionsThis interview study helps to disentangle the debate on GDTs by providing a better understanding of the moral views of GDT experts. The obtained insights provide valuable stepping-stones for a constructive debate about underlying value conflicts and call attention to topics that deserve further (normative) reflection. Further evaluation of these issues can facilitate the debate on and responsible development of GDTs. (shrink)

Control of our own beliefs is allegedly required for the truth of epistemic evaluations, such as S ought to believe that p , or S ought to suspend judgment (and so refrain from any belief) whether p . However, we cannot usually believe or refrain from believing at will. I agree with a number of recent authors in thinking that this apparent conflict is to be resolved by distinguishing reasons for believing that give evidence that p from reasons that (...) make it desirable to believe that p whether or not p is true. I argue however that there is a different problem, one that becomes clearer in light of this solution to the first problem. Someone’s approval of our beliefs is at least often a non-evidential reason to believe, and as such cannot change our beliefs. Ought judgments aim to change the world. But ‘ought to believe’ judgments can’t do that by changing the belief, if they don’t give evidence. So I argue that we should instead regard epistemic ought judgments as aimed mainly at influencing assertions that express the belief and other actions based on the belief, in accord with recent philosophical claims that we have epistemic norms for assertion and action.

By using case studies from the history of science as evidence for its claims, the philosophy of science can develop a more productive relation to its subject matter, the history of science. As might be expected, many problems involving the relation between theory and evidence in science reappear here as methodological problems about the relation between the philosophy of science and the history of science. For example, the most important of these difficulties involves the "contamination" of historical evidence by philosophical (...) theories. The difficulty may be resolved as follows: the history of science is "theory-laden", but not necessarily with the solutions to the problems it poses for philosophers. As a result, case studies can be used to test our explanatory theories about science as long as those case studies have not yet been reconstructed by the theory they are meant to test. Furthermore, once an explanatory theory has been " well -supported", we can, using that theory, go on to reconstruct case studies. Such a theory would thereby take on the force of a normative claim about science, bypassing what has been viewed as a fundamental disjunction between the descriptive and normative function of theory. From this point of view, insistence on a single criterion of demarcation as a "ground" for philosophical claims is misguided, since it prejudges a still -open question--is science homogeneous?--that can only be answered by further investigation of science.

The expansion of research on deep brain stimulation (DBS) and adaptive DBS (aDBS) raises important neuroethics and policy questions related to data sharing. However, there has been little empirical research on the perspectives of experts developing these technologies. We conducted semi-structured, open-ended interviews with aDBS researchers regarding their data sharing practices and their perspectives on ethical and policy issues related to sharing. Researchers expressed support for and a commitment to sharing, with most saying that they were either sharing (...) their data or would share in the future and that doing so was important for advancing the field. However, those who are sharing reported a variety of sharing partners, suggesting heterogeneity in sharing practices and lack of the broad sharing that would reflect principles of open science. Researchers described several concerns and barriers related to sharing, including privacy and confidentiality, the usability of shared data by others, ownership and control of data (including potential commercialization), and limited resources for sharing. They also suggested potential solutions to these challenges, including additional safeguards to address privacy issues, standardization and transparency in analysis to address issues of data usability, professional norms and heightened cooperation to address issues of ownership and control, and streamlining of data transmission to address resource limitations. Researchers also offered a range of views on the sensitivity of neural activity data (NAD) and data related to mental health in the context of sharing. These findings are an important input to deliberations by researchers, policymakers, neuroethicists, and other stakeholders as they navigate ethics and policy questions related to aDBS research.

Living agency is subject to a normative dimension (good-bad, adaptive-maladaptive) that is absent from other types of interaction. We review current and historical attempts to naturalize normativity from an organism-centered perspective, identifying two central problems and their solution: (1) How to define the topology of the viability space so as to include a sense of gradation that permits reversible failure, and (2) how to relate both the processes that establish norms and those that result in norm-following behavior. We (...) present a minimal metabolic system that is coupled to a gradient-climbing chemotactic mechanism. Studying the relationship between metabolic dynamics and environmental resource conditions, we identify an emergent viable region and a precarious region where the system tends to die unless environmental conditions change. We introduce the concept of normative field as the change of environmental conditions required to bring the system back to its viable region. Norm-following, or normative action, is defined as the course of behavior whose effect is positively correlated with the normative field. We close with a discussion of the limitations and extensions of our model and some final reflections on the nature of norms and teleology in agency. (shrink)

“Small” large cardinal notions in the language of ZFC are those large cardinal notions that are consistent with V = L. Besides their original formulation in classical set theory, we have a variety of analogue notions in systems of admissible set theory, admissible recursion theory, constructive set theory, constructive type theory, explicit mathematics and recursive ordinal notations (as used in proof theory). On the face of it, it is surprising that such distinctively set-theoretical notions have analogues in such disaparate (...) and relatively constructive contexts. There must be an underlying reason why that is possible (and, incidentally, why “large” large cardinal notions have not led to comparable analogues). My long term aim is to develop a common language in which such notions can be expressed and can be interpreted both in their original classical form and in their analogue form in each of these special constructive and semi-constructive cases. This is a program in progress. What is done here, to begin with, is to show how that can be done to a considerable extent in the settings of classical and admissible set theory (and thence, admissible recursion theory). The approach taken here is to expand the language of set theory to allow us to talk about (possibly partial) operations applicable both to sets and to operations and to formulate the large cardinal notions in question in terms of operational closure conditions; at the same time only minimal existence axioms are posited for sets. The resulting system, called Operational Set Theory, is a partial adaptation to the set-theoretical framework of the explicit mathematics framework Feferman (1975). The.. (shrink)

The article reconstructs the premises of the reception of analytic philosophy in jurisprudence and shows that the development of a method for clarifying the meanings of legal concepts is not least connected with the problem of legitimizing law enforcement. The article analyzes H.L.A. Hart’s approach to the problem of correlation between the “letter” and “spirit” of the law in the process of interpreting legal norms. The article argues that the process of interpretation is determined teleologically. In its limit, the (...) interpretation of legal norms presupposes the re-creation of the desired image of society, the reconstruction of such social ontology that is most consistent with the ideal of achieving social welfare. The article examines the collision of the “ideal of order” and the “ideal of justice” as two regulations of law enforcement. The author believes that the interpretation of this collision within the analytical tradition was characterized by a gradual movement from the ideal of “mechanical” law enforcement, which minimizes the creative role of the interpreter, to the ideal of flexible interpretation focused on achieving legal goals in a changing environment. It is noted that, according to analytic approach, a theoretical solution to this conflict was proposed due to the development of the ideas of an “open texture” of law. The author demonstrates that the development of the analytic tradition in jurisprudence has shown that the criticism of language and the interpretation of meanings are not technical tasks, but it presupposes the construction of a metaphysics of law. In this regard, the author concludes: the development of the ideas of the analytic tradition in jurisprudence demonstrates that the thesis about the absence of a positive program in analytic philosophy, put forward in the first article of the discussion, can be challenged.

attacks new defenders of foundationalism. Some simply took on the critics, 2 but others attempted to argue that even if the critics were right, only one form of foundationalism was suspect, not foundationalism itself. For, according to these defenders, foundationalism is not to be identified with the view of Classical Foundationalism (CE) that all of our knowledge rests on incorrigible beliefs. Rather foundationalism is the view that all of our knowledge rests on beliefs that are self-warranting in some sense. (...) Thus, even if CF is false, it does not follow that foundationalism is false. (shrink)

Abductive problems and their solutions are presented by means of justification logic. We introduce additional meta-constructions in order to generate and compare different solutions to the same abductive problem. Our approach has three advantages: (i) it makes structurally explicit the solution to an abductive problem (as it has a syntactic nature); (ii) it gives a precise meaning to the notion of evidence; (iii) it provides clear definitions and procedures for the comparison of solutions that can be adapted to different (...) needs.

The aim of this study is to justify the belief that there are biological normative mechanisms that fulfill non-trivial causal roles in the explanations (as formulated by researchers) of actions and behaviors present in specific systems. One example of such mechanisms is the predictive mechanisms described and explained by predictive processing (hereinafter PP), which (1) guide actions and (2) shape causal transitions between states that have specific content and fulfillment conditions (e.g. mental states). Therefore, I am guided by a specific (...) theoretical goal associated with the need to indicate those conditions that should be met by the non-trivial theory of normative mechanisms and the specific models proposed by PP supporters. In this work, I use classical philosophical methods, such as conceptual analysis and critical reflection. I also analyze selected studies in the field of cognitive science, cognitive psychology, neurology, information theory and biology in terms of the methodology, argumentation and language used, in accordance with their theoretical importance for the issues discussed in this study. In this sense, the research presented here is interdisciplinary. My research framework is informed by the mechanistic model of explanation, which defines the necessary and sufficient conditions for explaining a given phenomenon. The research methods I chose are therefore related to the problems that I intend to solve. In the introductory chapter, “The concept of predictive processing”, I discuss the nature of PP as well as its main assumptions and theses. I also highlight the key concepts and distinctions for this research framework. Many authors argue that PP is a contemporary version of Kantianism and is exposed to objections similar to those made against the approach of Immanuel Kant. I discuss this thesis and show that it is only in a very general sense that the PP framework is neo-Kantian. Here we are not dealing with transcendental deduction nor with the application of transcendental arguments. I argue that PP is based on reverse engineering and abduction inferences. In the second part of this chapter, I respond to the objection formulated by Dan Zahavi, who directly accuses this research framework of anti-realistic consequences. I demonstrate that the position of internalism, present in the so-called conservative PP, does not imply anti-realism, and that, due to the explanatory role played in it by structural representations directed at real patterns, it is justified to claim that PP is realistic. In this way, I show that PP is a non-trivial research framework, having its subject, specific methods and its own epistemic status. Finally, I discuss positions classified as the socalled radical PP. In the chapter “Predictive processing as a Bayesian explanatory model” I justify the thesis according to which PP offers Bayesian modeling. Many researchers claim that the brain is an implemented statistical probabilistic network that is an approximation of the Bayesian 7 rule. In practice, this means that all cognitive processes are to apply Bayes' rule and can be described in terms of probability distributions. Such a solution arouses objections among many researchers and is the subject of wide criticism. The purpose of this chapter is to justify the thesis that Bayesian PP is a non-trivial research framework. For this purpose, I argue that it explains certain phenomena not only at the computational level described by David Marr, but also at the level of algorithms and implementation. Later in this chapter I demonstrate that PP is normative modeling. Proponents of the use of Bayesian models in psychology or decision theory argue that they are normative because they allow the formulation of formal rules of action that show what needs to be done to make a given action optimal. Critics of this approach emphasize that such thinking about the normativity of Bayesian modeling is unjustified and that science should shift from prescriptive to descriptive positions. In a polemic with Shira Elqayam and Jonathan Evans (2011), I show that the division they propose into prescriptivism and Bayesian descriptivism is apparent, because, as I argue, there are two forms of prescriptivism, i.e. the weak and the strong. I argue that the weak version is epistemic and can lead to anti-realism, while the strong version is ontic and allows one to justify realism in relation to Bayesian models. I argue that a weak version of prescriptivism is valid for PP. It allows us to adopt anti-realism in relation to PP. In practice, this means that you can explain phenomena using Bayes' rule. This does not, however, imply that they are Bayesian in nature. However, the full justification of realism in relation to the Bayesian PP presupposes the adoption of strong prescriptivism. This position assumes that phenomena are explained by Bayesian rule because they are Bayesian as such. If they are Bayesian in nature, then they should be explained using Bayesian modeling. This thesis will be substantiated in the chapters “Normative functions and mechanisms in the context of predictive processing” and “Normative mechanisms and actions in predictive processing”. In the chapter “The Free Energy Principle in predictive processing”, I discuss the Free Energy Principle (hereinafter FEP) formulated by Karl Friston and some of its implications. According to this principle, all biological systems (defined in terms of Markov blankets) minimize the free energy of their internal states in order to maintain homeostasis. Some researchers believe that PP is a special case of applying this principle to cognition, and that predictive mechanisms are homeostatic mechanisms that minimize free energy. The discussion of FEP is important due to the fact that some authors consider it to be important for explanatory purposes and normative. If this is the case, then FEP turns out to be crucial in explaining normative predictive mechanisms and, in general, any normative biological mechanisms. To define the explanatory possibilities of this principle, I refer to the discussion of its supporters on the issue they define as the problem of continuity and discontinuity between life and mind. A critical analysis of this discussion and the additional arguments I have formulated have allowed me to revise the explanatory ambitions of FEP. I also reject the belief that this principle is necessary to explain the nature of predictive mechanisms. I argue that the principle formulated and defended by Friston is an important research heuristic for PP analysis. 8 In the chapter “Normative functions and mechanisms in predictive processing”, I start my analyzes by formulating an answer to the question about the normative nature of homeostatic mechanisms. I demonstrate that predictive mechanisms are not homeostatic. I defend the view that a full explanation of normative mechanisms presupposes an explanation of normative functions. I discuss the most important proposals for understanding the normativity of a function, both from a systemic and teleosemantic perspective. I conclude that the non-trivial concept of a function must meet two requirements which I define as explanatory and normative. I show that none of the theories I have invoked satisfactorily meets both of these requirements. Instead, I propose a model of normativity based on Bickhard's account, but supplemented by a mechanistic perspective. I argue that a function is normative when: (1) it allows one to explain the dysfunction of a given mechanism; (2) it contributes to the maintenance of the organism's stability by shaping and limiting possible relations, processes and behaviors of a given system; and when (3) (according to the representational and predictive functions) it enables explaining the attribution of logical values of certain representations / predictions. In such an approach, a mechanism is normative when it performs certain normative functions and when it is constitutive for a specific action or behavior, despite the fact that for some reason it cannot realize it either currently or in the long-term. Such an understanding of the normativity of mechanisms presupposes the acceptance of the epistemic hypothesis. I argue that this hypothesis is not cognitively satisfactory, and therefore the ontic hypothesis should be justified, which is directly related to adopting the position of ontic prescriptivism. For this reason, referring to the mechanistic theory of scientific explanations, I formulate an ontical interpretation of the concept of a normative mechanism. According to this approach, a mechanism or a function is normative when they perform such and such causal roles in explaining certain actions and behaviors. With regard to the normative properties of predictive mechanisms and functions, this means that they are the causes of specific actions an organism carries out in the environment. In this way, I justify the necessity of accepting the ontic hypothesis and rejecting the epistemic hypothesis. The fifth chapter, “Normative mechanisms and actions in predictive processing”, is devoted to the dark room problem and the related exploration-exploitation trade-off. A dark room is the state that an agent could be in if it minimized the sum of all potential prediction errors. I demonstrate that, in accordance with the basic assumption of PP about the need for continuous and long-term minimization of prediction errors, such a state should be desirable for the agent. Is it really so? Many authors believe it is not. I argue that the test of the value of PP is the possibility of a non-trivial solution of this problem, which can be reduced to the choice between active and uncertainty-increasing exploration and safe and easily predictable exploitation. I show that the solution proposed by PP supporters present in the literature does not enable a fully satisfactory explanation of this dilemma. Then I defend the position according to which the full explanation of the normative mechanisms, and, subsequently, the solution to the dilemma of exploration and exploitation, involves reference to the existence of constraints present in the environment. The constraints 9 include elements of the environment that make a given mechanism not only causal but also normative. They are therefore key to explaining the predictive mechanisms. They do not only play the role of the context in which the mechanism is implemented, but, above all, are its constitutive component. I argue that the full explanation of the role of constraints in normative predictive mechanisms presupposes the integration of individual models of specific cognitive phenomena, because only the mechanistic integration of PP with other models allows for a non-trivial explanation of the nature of normative predictive mechanisms that would have a strong explanatory value. The explanatory monism present in many approaches to PP makes it impossible to solve the problem of the dark room. Later in this chapter, I argue that the Bayesian PP is normative not because it enables the formulation of such and such rules of action, but because the predictive mechanisms themselves are normative. They are normative because they condition the choice of such and such actions by agents. In this way, I justify the hypothesis that normative mechanisms make it possible to explain the phenomenon of agent motivation, which is crucial for solving the dark room problem. In the last part of the chapter, I formulate the hypothesis of distributed normativity, which assumes that the normative nature of certain mechanisms, functions or objects is determined by the relations into which these mechanisms, functions or objects enter. This means that what is normative (in the primary sense) is the relational structure that constitutes the normativity of specific items included in it. I suggest that this hypothesis opens up many areas of research and makes it possible to rethink many problems. In the “Conclusion”, I summarize the results of my research and indicate further research perspectives. (shrink)

Agriculture does not follow stock-raising); b) racial characters have no relevance in development of civilization; c) we are not yet in a position to compare externally identical kinds of behaviour till we have not yet understood beliefs and intentions laying at their roots (for ex.: “From an ethnological point of view murder cannot be considered as a single phenomenon”; d) we should distinguish among different practices which are only superficially similar (fro ex. practices traditionally classified under the label “tabù”); e) there is as a fact just one normative ethic, constant in its contents but varying in its extension; f) the implication is not that we cannot judge behavior by members of other groups; it is only a recommendation of caution. -/- Bronislaw Malinowski (1884-1942): a) against Tylor’s and Frazer’s “magpie” methodology, field-work is required, a culture as a whole should be observed from inside; individual elements are incomprehensible; b) a culture is an organic whole; c) its elements are accounted for by their function (economy), avoiding non-observables (empio-criticism). -/- Ruth Benedict and Melville Herskovitz identify Boas’s approach with “cultural relativism”. Benedict: what is normal and abnormal is to be judged on a culture’s own standards, not on our own (“Anthropology and the Abnormal”). Herskovits: “Boas adumbrates what we have come to call cultural relativism” (The Mind, p. 10); “Judgements are based on experience, and experience is interpreted by each individual in terms of his own enculturation” (Man and his Works). -/- 4. How analytic philosophy understood and misunderstood the discussion 4.1. At the beginning of the 20th c., the new view in ethics was non-cognitivism (emotivist and subjectivist). Eric Westermark combines this view with an old-style ethnographic approach in support of relativity of moralities. Moralities are codes, or systems of emotive ‘disinterested’ reactions selected by evolution on their usefulness in terms of survival value for the society that is the carrier of such systems or codes. The moral relativity thesis: there are cases of disagreement that cannot be settled even after agreement about facts. 4.2 Anti-realists Brandt, Mackie, Gilbert, Harman adopt Westermark’s approach in a more sophisticated version: a) moralities are codes with an overall function and may be appraised only as wholes; b) variability is an argument for moral subjectivism; c) apparent legitimacy of deriving shift from ought is legitimized only within one institution d) morality should not be described but instead made, and existing moralities may be improved. Is it ‘real’ relativism? It is clearly subjectivism (a metaethical thesis). The normative thesis is that there better and worse codes, and survival values is the normative standard. -/- 4.3 Particularists MacIntyre, Sandel, Taylor, Wiggins, McDowell ‘Wittgensteinian’ prospectivist arguments bent to support weak-relativist claims MacIntyre: there is ‘incommensurability’ between different theoretical systems in both science and ethics. No argument is possible through different systems Different traditions may coexist for a long time without being able to bring their conflicts to a rational solution. -/- 4.4 Kantian universalists Baier, Gewirth, Rawls, Apel, Habermas Shared claim: justice concerns the right and is universal in so far as it may be based on minimal assumptions Other virtues are relative to context in so far as they are related to comprehensive views of the good - O’Neill criticism: a) it is an assumption shared by both alignments; b) after an alleged crisis brought about by alleged loss of metaphysical certainties, theories of justice have dropped demanding assumptions and kept universalism, virtue theories have kept demanding assumptions and dropped universalism; c) the opposition of virtue and justice has arisen in an unjustified way. O’Neill’s positive proposal: ‘constructive’ procedures may be adopted both (i) concerning all the range of virtues and (ii) across cultures once we abandon idealization and confine ourselves to abstraction from real-world cases. -/- 4.5 A metaethical relativist and anti-relativist normative ethicists: Bernard Williams Williams: vulgar relativism may be assumed to claim that: a) 'just' means 'just in a given society'; b) 'just in a given society' is to be understood in functionalist sense; c) it is wrong for one society’s members to condemn another society’s values. It is inconsistent since in (c) uses ‘just’ in a non-relative way that has been excluded in (a). William’s positive proposal: i) keep a number of substantive or thick ethical concepts that will be different in space and time; ii) admit that public choices are to be legitimized through recourse to more abstract procedures and relying on more thin ethical concepts. -/- 5. Critical remarks 5.1 The only real relativism available is ‘vulgar’ relativism (Westermark?) 5.2. Descriptive universalism (or absolutism) has a long pedigree, from Cicero on, reaching Boas himself but it is useless as an answer to normative questions 5.3. Twentieth-century philosophical discussion seems to discuss an ad hoc doctrine reconstructed by assembling obsolete philosophical ideas but ignoring the real theory of cultural relativism as formulated by anthropologists. -/- 6. A distinction between ethoi and ethical theories as a way out of confusions a)There are systems of conventions de facto existing. These may be studies from outside as phenomena or facts. b)There is moral argument and this, when studies from outside, is a fact, but this does not influence in any degree the possible validity of claims advanced. c) the difference between the above claims and Mackie’s criticism to Searle’s argument of the promising game is that promises, arguments etc. are also phenomena, but they are also communicative phenomena with a logical and pragmatic structure. -/- 7.Conclusions: a) cultural relativism, as a name for Boas’s methodology is a valuable discovery, and in this sense we are all relativists; b) ethical relativism, as an alleged implication of cultural relativism, has been argued in a philosophically quite unsophisticated way by Benedict and Herskovits; philosophers apparently discussed ethical relativism in the basis of a rather faint impression of what cultural relativism had been. c) a full-fledged ethical relativism has hardly been defended by anybody among philosophers; virtually no modern philosopher really argued a prescriptive version of the thesis; d) we may accept the grain of truth in ethical relativism by including relativist critique to ethical absolutism into a universalist normative doctrine that be careful in separating open-textured formulations of universal claims from culturally conditioned particular prescriptions. -/- .

This article develops a fresh approach to Jørgensen's Dilemma on the basis of Paul Horwich's “minimalist” view that our notion of truth is implicitly defined by the instances of the equivalence schema “The proposition that p is true if and only if p.” The “deflationary” claim that the truth predicate, far from referring to any deep property of propositions, merely plays the logical function of enabling us to take certain attitudes (e.g., acceptance or rejection) towards propositions the content of which (...) we are not completely acquainted with or do not want to state openly is argued to lend powerful support to the claim that normative reasoning is concerned with the “transmission” of truth and falsity in the very sense in which descriptive reasoning is commonly taken to be. This result is all the more valuable since the “minimal” sense in which normative propositions are ascribed the capability of being either true or false involves no questionable ontological commitment to the existence of a “world of norms” as opposed to the familiar world of objects and their properties.

TWENTIETH-CENTURY ETHICS. AFTER NIETZSCHE -/- Preface This book tells the story of twentieth-century ethics or, in more detail, it reconstructs the history of a discussion on the foundations of ethics which had a start with Nietzsche and Sidgwick, the leading proponents of late-nineteenth-century moral scepticism. During the first half of the century, the prevailing trends tended to exclude the possibility of normative ethics. On the Continent, the trend was to transform ethics into a philosophy of existence whose self-appointed task (...) was that of describing the human condition as consisting of choices, as unavoidable as arbitrary, without any attempt at providing criteria for making such choices. In the Anglo-Saxon countries, the heir of ethics was a philosophy of morality, that is, an analysis of the language of morality that intended to clarify valuations without trying to justify them. 1958 was the year of the normative turn that led to the Rehabilitation of practical philosophy, a turn followed by decades of controversies between distinct kinds of normative ethics: utilitarian, Kantian, virtue ethics. While the controversy was raging, a quiet revolution took place, that of applied ethics which surprisingly dissolved the controversy's very subject matter by providing methods for making convergence possible on intermediate principles even when no agreement was available about first principles. The normative turn and the revolution of applied ethics have led us, at the turn of the century, to a goal that was quite far from the starting point. Instead of scepticism and relativism that was the fashion at the beginning of the century, at the beginning of the third millennium impartial and universal moral arguments seem to hold the spot being supported, if not by a final rational foundation, at least by reasonableness, the most precious legacy of the Enlightenment. -/- ● TABLE OF CONTENTS -/- ● I Anglo-Saxon philosophy: naturalism 1. Dewey beyond evolutionism and utilitarianism 2. Dewey and anti-essentialist moral epistemology 3. Dewey and naturalist moral ontology 4. Dewey and normative ethics of conduct and function 5. Perry and semantic naturalism -/- ● II Anglo-Saxon philosophy: ideal utilitarianism and neo-intuitionism 1. Moore's critique of utilitarian empiricism 2. Moore on the naturalistic fallacy 3. Moore on the nature of intrinsic value 4. Moore on ideal utilitarianism 5. Prichard on the priority of the right over the good 6. Ross's coherentist moral epistemology 7. Ross's moral ontology: realism, pluralism, and non-naturalism 8. Ross's normative ethics of prima facie duties -/- The chapter reconstructs the background of ideas, concerns and intentions out of which Moore's early essays, the preliminary version, and then the final version of Principia Ethica originated. It stresses the role of religious concerns, as well as that of the Idealist legacy. It argues that PE is more a patchwork of somewhat diverging contributions than a unitary work, not to say the paradigm of a new school in Ethics. -/- ●III Anglo-Saxon philosophy: non-cognitivism 1. The Scandinavian School, the Vienna circle and proto-emotivism 2. Wittgenstein and the ineffability of ethics 3. Russell's and Ayer's radical emotivism 4. Stevenson and moderate emotivism 5. Stevenson and the pragmatics of moral language 6. Stevenson and the methods for solving ethical disagreement 7. Hare and prescriptivism The chapter reconstructs first the discussion after Moore. The naturalistic-fallacy argument was widely accepted but twisted to prove instead that the intuitive character of the definition of 'good', its non-cognitive meaning, in a first phase identified with 'emotive' meaning. Alfred Julius Ayer is indicated as a typical proponent of such non-cognitivist meta-ethics. More detailed discussion is dedicated to Bertrand Russell's ethics, a more nuanced and sophisticated doctrine, arguing that non-cognitivism does not condemn morality to arbitrariness and that the project of rational normative ethics is still possible, heading finally to the justification of a kind of non-hedonist utilitarianism. Stevenson's theory, another moderate version of emotivism is discussed at some length, showing how the author comes close to the discovery of the role of a pragmatic dimension of language as a basis for ethical argument. A section reconstructs the discussion from the Forties about Hume's law, mentioning Karl Popper's argument and Richard Hare's early non-cognitivist but non-emotivist doctrine named prescriptivism. -/- ●IV Anglo-Saxon philosophy: critics of non-cognitivism 1. Neo-naturalism and its objections to the naturalistic fallacy argument 2. Objections to Hume's law 3. Clarence Lewis and the pragmatic contradiction 4. Toulmin and the good reasons approach 5. Baier and moral reasons 5. Baier, social moralities and the absolute morality 6. Baier and the moral point of view 7. Baier and the contents of absolute ethics -/- ● V Continental philosophy: the philosophy of values 1. Max Weber and the polytheism of values 2. Phenomenology against psychologism and rationalism 3. Reinach and the theory of social acts 4. Scheler and the material ethics of values 5. Hartmann and the ontology of values 6. Plessner, Gehlen and the Philosophische Anthropologie -/- The chapter illustrates first the idea of phenomenology and the Husserl's project of a phenomenological ethic as illustrated in his 1908-1914 lectures. The key idea is dismissing psychology and trying to ground a new science of the apriori of action, within which a more restricted field of inquiry will be the science of right actions. Then the chapter illustrates the criticism of modern moral philosophy conducted in the 1920 lectures, where the main target is naturalism, understood in the Kantian meaning of primacy of common sense. The third point illustrate is Adolph Reinach's theory of social acts as a key the grounding of norms, a view that sketches the ideas 'discovered' later by Clarence I. Lewis, John Searle, Karl-Otto Apel and Jürgen Habermas. A final section discusses Nicolai Hartman, who always refused to define himself a phenomenologist and yet developed a more articulated and detailed theory of 'values' – with surprising affinities with George E. Moore - than philosophers such as Max Scheler, who claimed to be Husserl's legitimate heirs. -/- ● VI Continental philosophy: the critics of the philosophy of values 1. Freud, the Superego and Civilization 2. Heidegger on original ethos against ethics 3. Sartre and de Beauvoir on authenticity and ambiguity 4. Adorno and Horkheimer on emancipation and immoralism -/- ●VII Post-liberal theologians and religious thinkers 1. Barth on the autonomy of faith from ethics 2. Developments of Reformed moral theology after Barth 3. Bonhoeffer on the concrete divine command and ethics of penultimate realities 4. Developments of Reformed and Catholic moral theology after world war II 5. Baeck and the transformation of liberal Judaism 6. Rosenzweig against liberal Judaism 7. Buber and religion as the vital lymph of morality 8. Heschel and Judaism as a science of actions -/- The chapter examines the main protagonists of Christian theology and Jewish religious thinking in the twentieth century. It stresses how the main dilemmas of contemporary philosophical ethics lie at the root of the various path of inquiry taken by these thinkers. -/- ● VIII Normative ethics: neo-Utilitarianism 1. The discussion on act and rule utilitarianism 2. Hare on two-tiered preference utilitarianism 3. Harsanyi, Gauthier and rational choice ethics 4. Parfit, utilitarianism and the idea of a person 5. Brandt and indirect conscience utilitarianism -/- The chapter addresses the issue of the complex process of self-transformation Utilitarianism underwent after Sidgwick's and Moore's fatal criticism and the unexpected Phoenix-like process of rebirth of a doctrine refuted. Two examples give the reader a glimpse at this uproarious process. The first is Roy Harrod Wittgensteinian transformation of utilitarianism in pure normative ethics depurated from hedonism as well as from whatsoever theory of the good. This transformation results in preference utilitarianism combined with a 'Kantian' version of rule utilitarianism. The second is Richard Hare's two-level preference utilitarianism, where act utilitarianism plays the function of the eventual rational justification of moral judgments and rule-utilitarianism that of an action-guiding practical device. -/- ● IX Normative ethics: neo-Aristotelianism and virtue ethics 1. Hannah Arendt, action and judgement 2. Hans-Georg Gadamer and phronesis 3. Alasdair MacIntyre on practices, virtues, and traditions 5. Stuart Hampshire on deliberation 6. Bernard Williams and moral complexity 7. Feminist ethics -/- Sect 1 reconstructs the post-war rediscovery of ethics by many German thinkers and its culmination in the Sixties in the movement named 'Rehabilitation of practical philosophy' is described. Heidegger's most brilliant disciples were the promoters of this Rehabilitation. Hans-Georg Gadamer is a paradigmatic example. His reading of Aristotle's lesson I reconstructed, starting with Heidegger's lesson but then subtly subverting its outcome thanks to the recovery of the significant role of the notion of phronesis. Sect 3 discusses the three theses defended by Anscombe in 'Modern Moral Philosophy'. It argues that: a) her answer to the question "why should I be moral?" requires a solution of the problem of theodicy, and ignores any attempts to save the moral point of view without recourse to divine retribution; b) her notion of divine law is an odd one more neo-Augustinian than Biblical or Scholastic; c) her image of Kantian ethics and intuitionism is the impoverished image manufactured by consequentialist opponents for polemical purposes and that she seems strangely accept it; d) the difficulty of identifying the "relevant descriptions" of acts is not an argument in favour of an ethics of virtue and against consequentialism or Kantian ethics, and indeed the role of judgment in the latter is a response to the difficulties raised by the case of judgment concerning future action. The chapter gives a short look at further developments in the neo-naturalist current trough a reconstruction of Philippa Foot's and Peter Geach's critiques to the naturalist-fallacy argument and Alasdair MacIntyre's grand reconstruction of the origins and allegedly inevitable failure of the Enlightenment project of an autonomous ethic. -/- ● X Normative ethics: Kantian and rights-based ethics 1. Dialogical constructivism 2. Apel, Habermas and discourse ethics 3. Gewirth and rights-based ethics 4. Nagel on agent-relative reasons 5. Donagan and persons as ends in themselves Parallel to the neo-Aristotelian trend, there was in the Rehabilitation of practical philosophy a Kantian current. This current started with the discovery of the pragmatic dimension of language carried out by Charles Peirce and the Oxford linguistic philosophy. On this basis, Karl-Otto Apel singled out as the decisive proponent of the linguistic and Kantian turn in German-speaking ethics, worked out the performative-contradiction argument while claiming that this was able to provide a new rational and universal basis for normative ethics. The chapter offers an examination of his argument in some detail, followed by a more cursory reconstruction of Jürgen Habermas's elaboration on Apel's theory. -/- ● XI The applied ethics renaissance 1. Elisabeth Anscombe on the atom bomb 2. From medical ethics to bioethics 3. Rawls and public ethics 3. Nozick, Dworkin and further developments of public ethics 5. Sen and the revival of economic ethics -/- The chapter presents the revolution of applied ethics while stressing its methodological novelty, exemplified primarily by Beauchamp and Childress principles approach and then by Jonsen and Toulmin's new casuistry. The chapter argues that Rawls's distinction between a "political" and a "metaphysical" approach to the theory of justice, one central part of ethical theory, is a formulation of the same basic idea at the root of both the principles approach and the new casuistry, both discussed in the following chapter. The idea is that it is possible to reach an agreement concerning positive moral judgments even though the discussion is still open – and in Rawls' view never will be close – on the essential criteria for judgment. -/- ● XII Fin-de-siècle metaethics 1. Deontic logics 2. Anti-realism 3. External realism 4. Internal realism 5. Kantian constructivism -/- The chapter illustrates the fresh start of meta-ethical discussion in the Eighties and Nineties and the resulting new alignments: metaphysical naturalism, internal realism, anti-realism, and constructivism.

The problem of interdependence is crucial for understanding the climate, with its interactions between land, water and atmosphere, as well as with human activities, past and future. The concept of interdependence expresses two types of relationship, that of causality and that of responsibility. For the problems of climate governance as understood as a statistical average in the Conferences of the parties (COP), causal dependence is impossible to reconstruct precisely, notably because of the complexity of these phenomenons. However, dependence (...) does not only concern the domain of being, falling within the natural sciences and social sciences and human descriptivo-predictive. It also concerns the ought-to-be and therefore the normative sciences (ethics, political thery, law and normative economy). Here interdependence is much more problematic since it is opposed to freedom. The article discusses the various interdependencies and political solutions that are offered to take care of this needs, architectures for discussing climate change politically: systems (N. Luhmann) and deliberation (J. Habermas). He proposes then another solution, that of the moral and political consediration. (shrink)

Background In the last years, there has been an increase in publication of systematic reviews of normative literature or of normative information in bioethics. The aim of a systematic review is to search, select, analyse and synthesise literature in a transparent and systematic way in order to provide a comprehensive and unbiased overview of the information sought, predominantly as a basis for informed decision-making in health care. Traditionally, one part of the procedure when conducting a systematic review is an appraisal (...) of the quality of the literature that could be included. Main text However, while there are established methods and standards for appraising e.g. clinical studies or other empirical research, quality appraisal of normative literature in the context of a systematic review is still rather a conundrum – not only is it unclear how it could or should be done, but also the question whether it necessarily must be done is not settled yet. Based on a pragmatic definition of “normative literature” as well as on a typology of different types of systematic reviews of normative literature/information, this paper identifies and critically discusses three possible strategies of conducting quality appraisal. Conclusions The paper will argue that none of the three strategies is able to provide a general and satisfying solution to the problems associated with quality appraisal of normative literature/information. Still, the discussion of the three strategies allows outlining minimal conditions that elaborated strategies have to meet in future, and facilitates sketching a theoretically and practically promising strategy.

La sociologie classique a utilisé la notion d’ambivalence sociale pour désigner la combinaison, nécessaire, mais chargée de conflit, entre l’obéissance aux normes et la volonté d’affirmer sa liberté. Il faut distinguer cette notion de celle d’ambivalence culturelle, qui désigne la nécessité de suivre à la fois des exigences culturelles opposées, en particulier dans un rapport majorité/minorité. La figure de l’étranger dessinée par Georg Simmel est l’exemple type de cette ambivalence, source de frustrations, mais qui néanmoins représente la moins mauvaise (...) class='Hi'>solution possible. Après des siècles de raisonnements fondés sur la notion « ou... ou », nous ressentons la nécessité de nous placer en situation d’ambivalence.The notion of sociological ambivalence has been widely used to refer to the conflict-permeated combination of compliance with norms and search for individual autonomy. We must draw a distinction between this kind of ambivalence and a cultural ambivalence relating to the coexistence of two cultures to be inevitably found in a majority/minority relationship. The figure of the stranger designed by Georg Simmel is a classical example of this ambivalence, which induces frustrations, but represents the most acceptable solution possible. After centuries of dialectical thinking of the « either-or » type, we feel the urge to put ourselves in a situation of ambivalence. (shrink)

Neoclassical economic theory in its pretensions to scientific status is founded on one of the variants of a now discredited positivism. Neoclassical economic theory claims that there are two distinct areas of economic research: positive economics and normative economics. The former is assumed to deal with the cognitive as scientific content of economics while the later focuses on welfare or equity issues. I argue that the reliance of the whole theoretical structure of economics on the normative postulate of rationality (...) renders neoclassical economics a normative discipline. I also argue that neoclassical economics should thus be viewed as an instance of applied ethics rather than as applied mathematics, say. Finally, it is suggested that neoclassical economics, if its scientific pretensions are to be taken seriously, should be absorbed theoretically into general anthropology. (shrink)

This dissertation argues that an agent's particular commitments are an integral and necessary part of his autonomy. I refer to Hegel's Philosophy of Right to argue that the autonomous self is in fact a committed self. According to Hegel, freedom is only possible when the agent inhabits roles within a family, civil society, and the greater community of the state. These roles make up the agent's practical identity, or the set of commitments and characteristics around which he orients his actions. (...) His practical identity provides him with norms: he has specific obligations as, for instance, a parent, police officer, or judge. ;Chapter One critiques Christine Korsgaard's Kantian account of practical identity, arguing that it is inadequate because of its insistence on an ontologically divided self. Chapter Two argues that practical identity according to Hegel must include consideration of an agent's contingent circumstances. Chapter Three claims that Hegel's agent knows himself and other humans to possess universal rights and to be sources of moral certainty. Chapter Four discusses social institutions and the norms they generate. When the agent freely embraces roles in these institutions, he embraces the obligations that accompany those roles. He gives himself these obligations and is autonomous through them. ;Chapter Five argues that Hegel's definition of conscience crucially depends on his theory of practical identity. Hegel's conscience is not a source of arbitrary, unimpeachable conclusions but refers to the norms of rational institutions. It does not neglect an agent's particular commitments within those institutions such as commitments to particular causes, family members, or political organizations. It rather explains the freedom of his actions through those commitments. So defined, conscience allows for both inner certainty and external sanction. Chapter Six argues that a wide range of professions describe their ethical experience in terms of conscience, and that Hegel's definition of conscience makes sense of this experience. By referring to roles, Hegel's conscience also requires the agent to be involved in the evaluation and reformation of institutions. As such, his theory is of great relevance to contemporary ethical life. (shrink)

Normative nonrealism denies, first, that some things are good or bad independently of facts about the attitudes of moral agents and, second, that attitude-independent moral facts determine what is rational. This implies that facts about what is rational are logically prior to what is moral. Nonrealism commonly assumes (a) that moral realism is false or unjustifiable, (b) that there is a conceptual connection between morality and rationality and (c) that the particular theory of rationality is the correct account of rationality. (...) Facing the threat of relativism when abandoning (c) it is argued that (c) is at least dubious. Semantic considerations concerning the meaning of "rationality" are sketched and the full-information approach of decision making, intemalism and extemalism are discussed in the light of "Why care?"-questions with the resuh that these questions do serious damage to nonrealist approaches to rationality and reason-based morality.

I aim to analyze in this dissertation what a desirable basic institutional structure looks like from the perspective of rationality. While the main topic is thus normative in nature, I start by clarifying in the first part what the notion of rationality exactly entails. I do so by focusing explicitly on the economic conception of rationality, according to which a rational individual is motivated to serve his self-interest on the basis of cost-benefit calculations. Such a Homo Economicus is characterized by (...) his intentional and instrumental actions, his perfectly informed beliefs and his exogenously given and egoistic preferences. In my view, however, this model is inadequate if one aims to understand what it means to be rational. The requirements that actions should be instrumental, beliefs should be based on perfect information and preferences should be exogenously given and egoistic in nature turn out to be overly demanding in this respect. That is why I propose to drop these assumptions in what I label the minimal conception of rationality. Since the latter turns out to be very formal indeed, I propose two further alternatives, which focus not so much on the choice of means to achieve certain goals, as they focus on the choice of these goals themselves. According to the first, broad conception, actions are rational if they are based on good reasons, which are further qualified as well-informed beliefs and autonomous preferences. According to the second, expressive conception, actions, beliefs and preferences are rational if they express the things the individual at hand cares about. The latter requires that individuals can reflect upon and identify with their reasons, which implies a capacity to reflect upon and distance themselves from their own bundle of preferences. In the second part of this dissertation, I try to show the value and limitations of these conceptions by applying them to the context of large-scaled elections. In this respect, it becomes immediately clear that the economic conception fails to explain why quite a lot of people go out and vote. After all, since a single vote has only an infinitesimal impact on the electoral result, it does not enable people to serve their interests or realize their goals. This leads to the so-called voting paradox, according to which no rational individual will decide to vote. The standard solution is to assume that individuals vote because they derive satisfaction from the very act itself. However, this strategy is rather ‘ad hoc’ and does not explain how people vote once they find themselves inside the voting booth. The expressive conception of rationality does better in this respect. It suggests that people vote because they care about democracy in general or about a specific political candidate or ideology. Since they conceive of themselves as being a good citizen, they express this aspect of their identity by going out to vote. In the third part of this dissertation, I analyze more fully the normative implications of the different conceptions of rationality. More specifically, I try to answer the question which basic institutional structure is desirable if one assumes that people are by and large rational. This immediately shows that both the normative issue and the explanatory issue are closely connected. In my view, proposals regarding institutional design and reform should be based on empirically adequate models of individual actions and motivations. This search for a realistic utopia goes against the conventional strategy of most economists. They rely on the Homo Economicus model, even if this fails to explain individual behavior. To explain more fully what the normative implications are of the counterfactual assumption that all people are economically rational, I focus on the work of James Buchanan. In his theory of constitutional choice, he argues in favor of a minimal state whose only task is to make sure that the market functions properly. Buchanan thus favors strict constitutional limitations for governments, which tend to expand beyond legitimate borders as soon as politicians and public servants are allowed to serve their own interests. In my view, however, the abovementioned criticisms of the Homo Economicus model have theoretical as well as normative implications. After all, the empirically supported fact that a majority of individuals does not act in economically rational ways creates more room for legitimate government intervention. Expressively rational citizens will, for example, more easily agree on the necessity and desirability of a collective provision of certain public goods. In addition, expressively rational politicians and public servants can be more easily trusted to serve the public interest rather than their narrowly defined self-interest. As an alternative to Buchanan’s one-sided focus on economic rationality and the market, I focus on the work of Samuel Bowles en Herbert Gintis. More specifically, I explore their work on the phenomenon of strong reciprocity, which refers to the widespread tendency of people to reward prosocial behavior and punish antisocial behavior, even if this is costly for themselves. Since this is clearly economically irrational, Bowles and Gintis propose to complement the Homo Economicus model with the Homo Reciprocans model. This model, which comes close to the expressive conception of rationality, is able to incorporate the insight that social norms surrounding reciprocity, cooperation and fairness are crucial in regulating interactions. At the normative level, Bowles and Gintis stress that such norms often lead to socially desirable outcomes, since they enable people to live in harmony without relying on coercive and costly government interventions. This suggests that the debate between proponents of the market on the one hand and the state on the other hand neglects the importance of communities where people spontaneously interact on the basis of generally prosocial norms. As such, the insights of Bowles and Gintis lead to a defense of a basic institutional structure in which markets, states and communities mutually complement and reinforce each other. They also justify a general optimism as regards to the capacity and motivation of people to try and improve the rules and institutions that govern their everyday lives. (shrink)

We analyze the logical strength of theorems on marriage problems with unique solutions using the techniques of reverse mathematics, restricting our attention to problems in which each boy knows only finitely many girls. In general, these marriage theorems assert that if a marriage problem has a unique solution then there is a way to enumerate the boys so that for every m, the first m boys know exactly m girls. The strength of each theorem depends on whether the (...) underlying marriage problem is finite, infinite, or bounded. (shrink)

The critics in this volume raise several important challenges to the modal normativist position developed in Norms and Necessity, including whether the relation I claim holds between semantic rules and necessity claims generates spurious claims of metaphysical necessity, whether the view is circular (implicitly relying on a more 'robust' form of modal realism), and whether it conflicts with truth-conditional semantics. They also raise probing questions about how it compares to other views of modality, including a Lewisian view and an (...) essentialist view. In these replies, I respond to these challenges in ways that precisify the relevant understanding of ‘semantic rules' and the forms they can take, that make clearer the direction of explanation in modal normativism in ways that show the view doesn't rely on a more ‘robust’ form of modal realism, and that give reason for thinking that there is actually no conflict between modal normativism and truth-conditional semantics. I also aim to give a fuller assessment of how it compares to other approaches to modality, including an essentialist approach. (shrink)

The starting point of my analysis is the complexity of contemporary society. Complexity here refers more in particular to social complexity: the type of complexity that emerges from the relationships between human beings and the myriad of options and possibilities that exist in our society. A systems theoretical account of complexity elicits that this 'social abundance' necessitates selections. One way of enabling selections, and hence the reduction of complexity, is the formulation of norms. The central thesis of this account follows (...) from this observation: social complexity is a source of normativity, in the sense that social complexity generates – among others – normativity. Dealing with social complexity requires selections and a considerable range of selections, at their turn, require norms. From a somewhat different angle, we could say that social complexity entails both freedom of choice and force of choice. It is this combination of freedom and force that confronts our society with a profound problem. It translates, so to speak, social complexity into uncertainty: how to deal with all these options and possibilities, how to shape our interactions? An important aspect of the problem is the abundance of colliding heteronymous norms and a simultaneous lack of ethical norms that do not compromise our individual autonomy. The analysis of this ethical state of affairs draws upon the work of Zygmunt Bauman. The paper tentatively seeks to outline the social theoretical requirements of an ethic that takes issue with the uncertainty of choice. (shrink)

Ben Saunders claims that actual consent is not necessary for organ donation due to ‘normative consent’, a concept he borrows from David Estlund. Combining normative consent with Peter Singer's ‘greater moral evil principle’, Saunders argues that it is immoral for an individual to refuse consent to donate his or her organs. If a presumed consent policy were thus adopted, it would be morally legitimate to remove organs from individuals whose wishes concerning donation are not known. This paper disputes Saunders' (...) arguments. First, if death caused by the absence of organ transplant is the operational premise, then, there is nothing of comparable moral precedence under which a person is not obligated to donate. Saunders' use of Singer's principle produces a duty to donate in almost all circumstances. However, this premise is based on a flawed interpretation of cause and effect between organ availability and death. Second, given growing moral and scientific agreement that the organ donors in heart-beating and non-heart-beating procurement protocols are not dead when their organs are surgically removed, it is not at all clear that people have a duty to consent to their lives being taken for their organs. Third, Saunders' claim that there can be good reasons for refusing consent clashes with his claim that there is a moral obligation for everyone to donate their organs. Saunders' argument is more consistent with a conclusion of ‘mandatory consent’. Finally, it is argued that Saunders' policy, if put into place, would be totalitarian in scope and would therefore be inconsistent with the freedom required for a democratic society. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Self-Culture in Emerson’s Schellingian Solution to FateNicholas L. Guardiano (bio)Professor of English literature, President of Yale University, and Commissioner of Major League Baseball, Angelo Bartlett Giamatti (1938–1989), delighted in saying that Emerson “is as sweet as barbed wire.”1 Giamatti understood the full range of Emerson’s thought, which spans the highs and lows of the human condition. Writings such as “Experience,” “Illusions,” “The Tragic,” and “Fate” demonstrate the transcending (...) of Emerson’s transcendentalism beyond any soft Romanticism or naïve idealism. They consistently assert the reality of antagonistic forces pervading human experience and nature. “The Tragic” opens with the lines: “He has seen but half the universe who never has been shown the House of Pain. As the salt sea covers more than two thirds of the surface of the globe, so sorrow encroaches in man on felicity” (CW 10:334).2 “Fate” similarly insists: “We cannot trifle with this reality [of fate], this cropping-out in our planted gardens of the core of the world. No picture of life can have any veracity that does not admit the odious facts” (CW 6:11; my emphasis). Emerson was made intimately aware of the House of Pain by his own personal hardships. To name only a few, there was the death of his first wife Ellen at age 19 from tuberculosis, a rheumatic eye disease that left Emerson nearly blind for months, the terrible loss of his five-year old son Waldo to scarlet fever, the untimely deaths of his two brothers Charles and Edward in their 20s, a fire that partially destroyed the Emerson family home, and the inexorable mental decline into aphasia afflicting Emerson in his final years. Emerson further bore sympathetic witness to the hardships of his friends, family, and community. In addition, he lived through the national crisis of the American Civil War, and was a committed abolitionist willing to face head on the real evils of slavery. These experiences and others were a discipline in the tragic [End Page 28] constitution of the world. Furthermore, they provided hints on how to make one’s way through it.3In this essay, I aim to do some justice to Emerson’s mature transcendentalism by examining his metaphysical-ethical co-principles of fate and freedom, or necessity and power. These co-principles are the central topic of the essay “Fate,” which appeared as the opening chapter of the book The Conduct of Life (1860). There, Emerson somewhat paradoxically admits both principles as opposing forces, and attempts to show their compatibility using a Schellingian dialectic. After presenting Emerson’s understanding of fate and an interpretation of his metaphysical solution to it, I follow up on the primary ethical concern that opens the essay and book, namely “How shall I live?” (CW 6:1). To that end, I attempt to flesh out the ethical character of a life that embraces fate in terms of an Emersonian project of self-culture. My methodological approach throughout evolves progressively from the interpretation to the expansion of Emerson’s ideas. Its first section examines his philosophy as an offshoot of the world-historical line of thought extending from Plato to the Neoplatonists, Eriugena, Spinoza, Goethe, and Schelling, among others. Later philosophers, scientists, and artists who took inspiration from Emerson’s transcendentalism, including Charles Peirce, the Hudson River School painters, Wallace Stevens, and Loren Eiseley, follow the same intellectual trajectory.4 Further taking up the torch, my second section creatively amplifies Emerson’s insights for an ethics of self-culture, and in this way argues for the truth of his Schellingian form of freedom.I. The Problem and Its SolutionFor Emerson, fate is real. It consists in the “immovable limitations” and necessary “laws of the world” (CW 6:2). These limits or laws occur in the conduct of life not so much as theoretical abstractions or remote chains of efficient [End Page 29] causality but as impositions on our will, both from within and without. On the one hand, we are confronted by the rough and tumble of nature, the outside environment in which we live. Serious in Emerson’s nineteenth century and remaining so today are... (shrink)

Normative nonrealism denies, first, that some things are good or bad independently of facts about the attitudes of moral agents and, second, that attitude-independent moral facts determine what is rational. This implies that facts about what is rational are logically prior to what is moral. Nonrealism commonly assumes (a) that moral realism is false or unjustifiable, (b) that there is a conceptual connection between morality and rationality and (c) that the particular theory of rationality is the correct account of rationality. (...) Facing the threat of relativism when abandoning (c) it is argued that (c) is at least dubious. Semantic considerations concerning the meaning of "rationality" are sketched and the full-information approach of decision making, intemalism and extemalism are discussed in the light of "Why care?"-questions with the resuh that these questions do serious damage to nonrealist approaches to rationality and reason-based morality.

This paper relates to a formal statement of the mechanisms that are thought minimally necessary to underpin consciousness. This is expressed in the form of axioms. We deem this to be useful if there is ever to be clarity in answering questions about whether this or the other organism is or is not conscious. As usual, axioms are ways of making formal statements of intuitive beliefs and looking, again formally, at the consequences of such beliefs. The use of this style (...) of exposition does not entail a claim to provide a mathematically rigorous formal deductive system. Conventional mathematical notation is used to achieve clarity, although this is elaborated with natural language in an attempt to reduce terseness. In our view, making the approach axiomatic is synonymous with building clear usable tests for consciousness and is therefore a central feature of the paper. The extended scope of this approach is to lay down some essential properties that should be considered when designing machines that could be said to be conscious. In the broader discussion about the nature of consciousness and its neurological mechanisms, it may seem to some that axiomatisation is premature and continues to beg many questions. However, the approach is meant to be open- ended so that others can build further axiomatic clarifications that address the very large number of questions which, in the search for a formal basis for consciousness, still remain to be answered. Of course, in discussions about consciousness many will also argue that the subject is not one that may ever be formally addressed by means of axioms. The view taken in this paper is 'let's try to do it and see how far it gets'. (shrink)

Although Daniel Engster's “caring” human rights are, on the surface, a compelling way to bring the concept of care into the international political realm, I argue they actually serve to perpetuate some of the same problems of mainstream human-rights discourses. The problem is twofold. First, Engster's particular care theory relies on an uncritical acceptance of our dependence relations. It can, therefore, not only overlook how local and global institutions, norms, and the marketplace shape our relations of dependence, but also serve (...) to further naturalize our current dependence relations. Second, Engster's caring human rights are only minimally feminist, which means that they do not pay attention to the way in which women's full and equal political participation is a necessary component to challenging and overcoming the oppression, marginalization, and exploitation of women and their caring labor worldwide. Although I am sympathetic to Engster's goals and some of his proposed policy solutions, I argue that we should not abandon the critical, feminist lens of care ethics in favor of “caring” human rights that cannot overcome the care critique of mainstream human-rights discourses.

A claim for minimalism about ‘real’ on the model of minimalism about ‘true’. The article, in effect, develops J.L. Austin’s remark that with ‘real’, the negative ‘wears the trousers’. The development is then exploited for a proposed elucidation of Plato’s discussion of the fields of knowledge and belief in his Republic. It is proposed that Plato was striving for something whose futility was a leading theme of Wittgenstein’s later philosophy.

Using birth stories as our object of inquiry, this article examines the ways in which normative discourses about gender, disability and Down syndrome construct the birth stories of three mothers of children with Down syndrome. Their stories are composed of the mothers’ recollections of the first hours after birth as a time when their infants are separated from them and their postpartum needs are ignored. Together, their stories illustrate socio-cultural tropes that position Down syndrome as a dangerous form of (...) the “other” and mothers who give birth to children with Down syndrome as implicated in transgressing cultural norms.

Very few scholars discuss the moral basis of the right of persons accused of crimes to be supplied with attorneys if they cannot afford them. More discussion of the topic is needed, in particular because political theorists who prefer a minimal state deny that indigent persons have such a moral right. This article addresses their contentions by developing three arguments for supplying poor persons accused of crimes with defense attorneys. First, doing so will prevent state officials from (...) becoming emboldened in their dealings with the poor, such that they might come to pose a threat to the non-poor. Second, poor persons who believe that the state does not treat them fairly will have reduced incentives to abide by the law, which will, in turn, increase the cost of the minimal state. Third, the better off should show solidarity with the poor in demanding that the minimal state honor all citizens’ rights to life, liberty, and property. Crucial to these arguments is the claim that a right of indigent defense is unlike other welfare rights in that securing it protects other basic moral rights that minimal statists acknowledge.

Objective: To identify factors that predict physicians’ intent to comply with the American Medical Association’s ethical guidelines on gifts from the pharmaceutical industry.Methods: A survey was designed and mailed in June 2004 to a random sample of 850 physicians in Florida, USA, excluding physicians with inactive licences, incomplete addresses, addresses in other states and pretest participants. Factor analysis extracted six factors: attitude towards following the guidelines, subjective norms , facilitating conditions , profession-specific precedents , individual-specific precedents and intent. (...) Multivariate regression modelling was conducted.Results: Surveys were received from 213 physicians representing all specialties, with a net response rate of 25.5%. 62% of respondents were aware of the guidelines; 50% had read them. 48% thought that following the guidelines would increase physicians’ credibility and professional image; 68% agreed that it was important to do so. Intent to comply was positively associated with attitude, subjective norms, facilitators and sponsorship of continuing medical education events, while individual-specific precedents had a negative relationship with intent to comply. Predictors of intent were attitude, subjective norms, the interaction term , sponsorship of CME events and individual-specific precedents.Conclusions: Physicians are more likely to follow the AMA guidelines if they have positive attitudes towards the guidelines, greater subjective norms, fewer expectations of CME sponsorship and fewer individual-specific precedents. Physicians believing that important individuals or organisations expect them to comply with the guidelines are more likely to express intent, despite having fewer beliefs that positive outcomes would result through compliance.

The nonlinear differential equation governing the periodic motion of the one-dimensional, undamped, and unforced cubic-quintic Duffing oscillator is solved exactly by obtaining the period and the solution. The period is given in terms of the complete elliptic integral of the first kind and the solution involves Jacobian elliptic functions. We solve the cubic-quintic Duffing equation under arbitrary initial conditions. Physical applications are provided. The solution to the mixed parity Duffing oscillator is also formally derived. We illustrate the (...) obtained results with concrete examples. We give high accurate trigonometric approximations to the Jacobian function cn. (shrink)

Moral Case Deliberations are reflective dialogues with a group of participants on their own moral dilemmas. Although MCD is successful as clinical ethics support, it also has limitations. 1. Lessons learned from individual MCDs are not shared in order to be used in other contexts 2. Moral learning stays limited to the participants of the MCD; 3. MCD requires quite some organisational effort, 4. MCD deals with one individual concrete case. It does not address other, similar cases. These (...) limitations warrant research into complementary ways of providing CES to healthcare professionals. Our research objective was therefore to develop a low threshold CES tool based on a series of MCDs on autonomy in long-term care. We used a qualitative research design in which we analyzed the process and content of a series of MCDs, combined with reflections on the theoretical background of MCD. In total 28 MCDs were analyzed by means of a thematic content analysis. In various rounds of development, the results of the analysis were combined with theoretical reflections on CES. Consequently, the tool was evaluated in three focus groups and adjusted. The CES tool, called ‘moral compass’, guides the users through a series of six subsequent questions in order to methodically reflect on their concrete moral dilemma, in the form of a booklet of 23 pages. It combines a methodical element that encourages and structures a reflection process with a substantive element, including norms, values, options, strategies, and insights regarding dealing with client autonomy. By using data from a series of MCDs, combined with theoretical reflections on MCD, ethics support and moral learning, we developed a thematic, low-threshold CES tool that supports healthcare professionals in daily practice in dealing with moral questions regarding client autonomy. It integrates examples and insights from earlier MCDs on the same topic. The moral compass is not a replacement of, but can be used complementary to MCD. The feasibility and impact of the moral compass need to be investigated in an evaluative follow-up study. The methodology presented in this paper may be used to develop moral compasses on different topics in various healthcare organizations. (shrink)

Four excellent essays which attempt, with admirable clarity and simplicity and in amazingly brief scope, to present the outline of an ethical viewpoint integrating a teleological naturalistic self-realizationism, intuitionistic ideal utilitarianism, and the ethical insights of Christianity. The semantic-epistemological issue between intuitionism and naturalism is neglected, but there are clear indications that if pressed, the nod would go to the latter. Self-realization is not taken as the end--in view of right choice; on the contrary, it is rejected as such (...) in favor of ideal utilitarianism, though it remains basic as the "ground or reason" why conduct aiming at that end is right. Designed for and understandable by the intelligent layman, these essays should interest the professional student of ethics as well.--L. K. B. (shrink)

The norm of assertion, to be in force, is a social norm. What is the content of our social norm of assertion? Various linguistic arguments purport to show that to assert is to represent oneself as knowing. But to represent oneself as knowing does not entail that assertion is governed by a knowledge norm. At best these linguistic arguments provide indirect support for a knowledge norm. Furthermore, there are alternative, non-normative explanations for the linguistic data (...) (as in recent work from Van Elswyk). Direct arguments would rely on normative judgments about the permissibility or impermissibility of assertions with and without the speaker knowing the content asserted. John Turri's work experimental results purport to show that our norm of assertion is factive, and probably knowledge. But as a number of recent experimentalists (Kneer, Reuter and Broessel, Marsili and Wiegmann) have shown, Turri's results rely on the problemmatic use of 'should' as in 'Maria should assert that she owns a 1990 watch.' Correcting for this, these experimentalists provide strong evidence that our norm of assertion is not factive. The standard reply to evidence like this from the assertion of unlucky falsehoods is the excuse maneuver. But Marsili and Wiegmann, following Turri's protocol for testing for excuse validation, show that participants who judge that assertions unlucky falsehoods are permissible are not guilty of excuse validation. Given our current understanding of the experimental evidence, knowledge is not our norm of assertion. (shrink)

Five experiments investigated how people use categories to make inductions about objects whose categorisation is uncertain. Normatively, they should consider all the categories the object might be in and use a weighted combination of information from all the categories: bet-hedging. The experiments presented people with simple, artificial categories and asked them to make an induction about a new object that was most likely in one category but possibly in another. The results showed that the majority of people focused on (...) the most likely category in making inductions, although there was a group of consistently normative responders who used information from both categories (about 25% of our college population). Across experiments the overall pattern of results suggests that performance in the task is improved not by understanding the underlying principles of bet-hedging but by increasing the likelihood that multiple categories are in working memory at the time of the induction. We discuss implications for improving everyday inductions. (shrink)
