Tense logics in the bimodal propositional language are investigated with respect to the Finite Model Property. In order to prove positive results techniques from investigations of modal logics above K4 are extended to tense logic. General negative results show the limits of the transfer.

Richard Feynman has claimed that anti-particles are nothing but particles `propagating backwards in time'; that time reversing a particle state always turns it into the corresponding anti-particle state. According to standard quantum field theory textbooks this is not so: time reversal does not turn particles into anti-particles. Feynman's view is interesting because, in particular, it suggests a nonstandard, and possibly illuminating, interpretation of the CPT theorem. In this paper, we explore a classical analog of Feynman's view, in the context of (...) the recent debate between David Albert and David Malament over time reversal in classical electromagnetism.

Zeno argued that since at any instant an arrow does not change its location, the arrow does not move at any time, and hence motion is impossible. I discuss the following three views that one could take in view of Zeno's argument:(i) the "at-at" theory, according to which there is no such thing as instantaneous velocity, while motion in the sense of the occupation of different locations at different times is possible,(ii) the "impetus" theory, according to which instantaneous velocities do (...) exist but these are only contingently and causally related to the temporal developments of positions,(iii) the "no instants" theory, according to which instants in time do not exist, and hence instantaneous velocities do not exist, while motion, in the sense of different areas occupied during different time intervals, is possible.I argue that, despite the fact that there have been interesting and relevant developments in mathematics and physics since the time of Zeno, each of these views still has serious drawbacks.

Mental, mathematical, and moral facts are difficult to accommodate within an overall worldview due to the peculiar kinds of properties inherent to them. In this paper I argue that a significant class of social entities also presents us with an ontological puzzle that has thus far not been addressed satisfactorily. This puzzle relates to the location of certain social entities. Where, for instance, are organizations located? Where their members are, or where their designated offices are? Organizations depend on their members (...) for their existence, but the members of an organization can be where the organization is not. The designated office of an organization, however, need be little more than a mailbox. I argue that the problem can be solved by conceptualizing the relation between social entities and non-social entities as one of constitution, a relation of unity without identity. Constituted objects have properties that cannot be reduced to properties of the constituting objects. Thus, my attempt to solve the Location Problem results in an argument in favor of a kind of non-reductive materialism about the social. (shrink)

This paper investigates partitions of lattices of modal logics based on superintuitionistic logics which are defined by forming, for each superintuitionistic logic L and classical modal logic , the set L[] of L-companions of . Here L[] consists of those modal logics whose non-modal fragments coincide with L and which axiomatize if the law of excluded middle p V p is added. Questions addressed are, for instance, whether there exist logics with the disjunction property in L[], whether L[] contains a (...) smallest element, and whether L[] contains lower covers of . Positive solutions as concerns the last question show that there are (uncountably many) superclean modal logics based on intuitionistic logic in the sense of Vakarelov [28]. Thus a number of problems stated in [28] are solved. As a technical tool the paper develops the splitting technique for lattices of modal logics based on superintuitionistic logics and ap plies duality theory from [34]. (shrink)

Intuitions about intentional action have turned out to be sensitive to normative factors: most people say that an indifferent agent brings about an effect of her action intentionally when it is harmful, but unintentionally when it is beneficial. Joshua Knobe explains this asymmetry, which is known as ‘the Knobe effect’, in terms of the moral valence of the effect, arguing that this explanation generalizes to other asymmetries concerning notions as diverse as deciding and being free. I present an alternative explanation (...) of the Knobe effect in terms of normative reasons. This explanation generalizes to other folk psychological notions such as deciding, but not to such notions as being free. I go on to argue, against Knobe, that offering a unified explanation of all the asymmetries he discusses is in fact undesirable. (shrink)

Famously Ryle imagined a visitor who has seen the colleges, departments, and libraries of a university but still wonders where the university is. The visitor fails to realize that the university consists of these organizational units. In this paper I ask what exactly the relation is between institutional entities such as universities and the entities they are composed of. I argue that the relation is constitution, and that it can be illuminated in terms of constitutive rules. The understanding of the (...) ontology of institutions that constitutive rules provide, however, is incomplete. In order to capture the practical significance of institutions, I introduce the notion of a status rule. Status rules concern the normative powers of institutions. The status account of institutions defended here is used to solve the problem of freestanding status terms: it turns out to be rather difficult to identify the entities of which statuses such as corporations and electronic money are composed. Unable to solve this problem, Searle concludes that they are created out of thin air. I criticize this claim and argue that these statuses are imposed on persons. (shrink)

Institutions are normative social structures that are collectively accepted. In his book Making the Social World, John R. Searle maintains that these social structures are created and maintained by Status Function Declarations. The article’s author criticizes this claim and argues, first, that Searle overestimates the role that language plays in relation to institutions and, second, that Searle’s notion of a Status Function Declaration confuses more than it enlightens. The distinction is exposed between regulative and constitutive rules as being primarily a (...) linguistic one: whereas deontic powers figure explicitly in regulative rules, they feature only implicitly in constitutive rules. Furthermore, he contends that Searle’s collective acceptance account of human rights cannot adequately account for the fact that people have these rights even when they are not recognized. Finally, It is argued that a conception of collective intentionality that involves collective commitment is needed in order to do justice to the normative dimension of institutions. (shrink)

The book offers the first systematic comparative treatment of the thoughts of Nietzsche and Merleau-Ponty. Through an account of each philosopher's thought as organized around their ambiguous relationship with the concept of truth, the book offers an elucidation of the concept of ambiguity and its dependence on the absolute as one of the determining features of modern thinking.

The task of transforming Durkheim's sociological perspective into an explanation of poverty in rural areas carries a triple handicap: Durkheim was not concerned with material well-being, he did not conceptualize structures of inequality, and his explanation of the division of labor was flawed. His late book on religion, however, contains an explanation of institutional innovation which offers a new starting point for understanding formal dimensions such as differentiation and pluralism, and these in turn as they are related to poverty. When (...) these dimensions are combined with technical organization, differences in welfare can be explained. When the summary formula for this combination of structure and technology is compared with those for Marxist and conventional economic explanations, the result is a dramatic contrast between the two materialist theories and a true sociological position.

The general claims of this paper are as follows. As a result of chaotic dynamics we can usually not know what the deterministic causes of events are. There will, however, be invariant forwards transition chances from earlier types of events, which we typically call the causes, to later types of events, which we typically call the effects. There will be no invariant backwards transition chances between these types of events. This asymmetry has the same origin and explanation as the arrow (...) of time of thermodynamics. (shrink)

Does the practice of psychology make a significant and positive contribution to human welfare and the struggle for a good society? This book presents a reinvigorating look at psychology and its societal purpose, offering a bold new philosophical foundation from which professionals in the field can deeply examine their work.

In chapter 3, we reflected on the view that the fallacies on the traditional list are inherently dialectical. The answer proposed there was that, with the possible exception of, e.g., begging the question and many questions, they are not. The aim of the present chapter is to cancel theispossibility by showing that begging the question and many questions are not in fact dialectical fallacies. The reason for this is not that question-begging and many questions aren’t (at least dominantly) dialectical practices. (...) The reason is that, dialectical or not, they are not fallacies. That begging the question, BQ for short, is a fallacy is an idea which originates with Aristotle. Given logic’s already long history, it should not be surprising that Aristotle’s views of these matters have in some ways been superseded. But the traditional view retains the original connection between conception and instantiation. Whereas BQ in Aristotle’s sense is said to be a fallacy in Aristotle’s sense, so too is BQ in the modern sense said to be a fallacy in the modern (i.e., EAUI) sense.[1] As currently conceived of, BQ and fallacies can be characterized in the following ways.

This essay discusses the role of the notions of reference, truth, and meaning in historical representation. Four major claims will be argued. First, conditional for all meaningful discussion of historical representation is that one radically discards from one's mind the paradigm of the true statement and all the epistemological and ontological problems occasioned by it. Second, representation is not a two-place, but a three-place operator: in representation a represented reality is represented by a representation focusing on certain aspects of represented (...) reality . Third, applying the notions of reference, truth, and meaning to historical representations compels us to give them a content basically different from the ones they have in contemporary philosophy of language and science. Fourth, it will be shown that in representation, meaning precedes truth—and not the other way around as in most of contemporary philosophy of language. (shrink)

One of our more fundamental beliefs is that causal chains are continuous in time: we believe that every influence from the past upon the future runs through the present. I argue that this tenet, given certain data, can force conceptual changes upon us. I attempt to formulate a heuristic for discovery, based as explicitly as possible upon this tenet, and illustrate it by means of several examples, one of which is Mendel's discovery of genes.

Human cognition is unique in the way in which it relies on combinatorial (or compositional) structures. Language provides ample evidence for the existence of combinatorial structures, but they can also be found in visual cognition. To understand the neural basis of human cognition, it is therefore essential to understand how combinatorial structures can be instantiated in neural terms. In his recent book on the foundations of language, Jackendoff described four fundamental problems for a neural instantiation of combinatorial structures: the massiveness (...) of the binding problem, the problem of 2, the problem of variables, and the transformation of combinatorial structures from working memory to long-term memory. This paper aims to show that these problems can be solved by means of neural “blackboard” architectures. For this purpose, a neural blackboard architecture for sentence structure is presented. In this architecture, neural structures that encode for words are temporarily bound in a manner that preserves the structure of the sentence. It is shown that the architecture solves the four problems presented by Jackendoff. The ability of the architecture to instantiate sentence structures is illustrated with examples of sentence complexity observed in human language performance. Similarities exist between the architecture for sentence structure and blackboard architectures for combinatorial structures in visual cognition, derived from the structure of the visual cortex. These architectures are briefly discussed, together with an example of a combinatorial structure in which the blackboard architectures for language and vision are combined. In this way, the architecture for language is grounded in perception. Perspectives and potential developments of the architectures are discussed. Key Words: binding; blackboard architectures; combinatorial structure; compositionality; language; dynamic system; neurocognition; sentence complexity; sentence structure; working memory; variables; vision.

Virtue and Psychology: Pursuing Excellence in Ordinary Practices by Fowers represents the most extensive effort to date to mine the resources of virtue ethics for theory and practice in psychology. Building on this work, I explore some of the implications of the virtue ethics perspective for the fields of psychology and psychotherapy, including helping to overcome individualism and instrumentalism, elaborating a conception of “internal” as opposed to merely “external” goods, clarifying the nature of “character strengths,” developing further the idea of (...) “strong relationality” in the sphere of human action, and aiding psychology in general in the effort to characterize a good or successful life. 2012 APA, all rights reserved).

The effect of prism adaptation on movement is typically reduced when the movement at test (prisms off) differs on some dimension from the movement at training (prisms on). Some adaptation is latent, however, and only revealed through further testing in which the movement at training is fully reinstated. Applying a nonlinear attractor dynamic model (Frank, Blau, & Turvey, 2009) to available data (Blau, Stephen, Carello, & Turvey, 2009), we provide evidence for a causal link between the latent (or secondary) (...) aftereffect and an additive force term that is known to account for symmetry breaking. The evidence is discussed in respect to the hypothesis that recalibration aftereffects reflect memory principles (encoding specificity, transfer-appropriate processing) oriented to time-translation invariance—when later testing conserves the conditions of earlier training. Forgetting or reduced adaptation effects follow from the loss of this invariance and are reversed by its reinstatement. (shrink)

This critical note responds to Guiaşu and Tindale’s “Logical fallacies and invasion biology,” from our perspective as ecologists and philosophers of science engaged in debates about invasion biology and invasive species. We agree that “the level of charges and dismissals” surrounding these debates might be “unhealthy” and that “it will be very difficult for dialogues to move forward unless genuine attempts are made to understand the positions being held and to clarify the terms involved.” Although they raise several important scientific, (...) conceptual, and ethical issues at the foundations of invasion biology, we believe Guiaşu and Tindale’s attempts to clarify the debate were unsuccessful. Like some other critics of the field, they tend to misrepresent invasion biology by cherry-picking and constructing “straw people,” inaccurately portraying invasion biology, and thus failing to elevate the dialogue. In this critique, we clarify areas in the invasion biology literature misrepresented by Guiaşu and Tindale. We attempt to provide a more balanced view of areas of reasonable debate within invasion biology, including disputes about empirical evidence, diverse risk attitudes, and other diverse ethical commitments.

ABSTRACTThe point of departure of this essay is the intuition that the relationship between the past and the present should be conceived of in terms of temporal distance. The spatial metaphor of distance at work in this intuition is thought to provide the basis for the epistemological model appropriate for understanding the nature of historical knowledge. This results in two claims: 1) epistemology is the philosophical instrument we must rely upon for understanding historical writing, and 2) the metaphor of distance (...) is—whether one is aware of it or not—the model for most, if not all, epistemological thought. This essay discusses the pros and cons of these two claims. It argues that the two claims are indeed the best way to begin our analysis of the relationship between the past and the historical text or representation. However, we cannot afford to stop there; indeed, we must ask ourselves where the associations we have with the metaphor of temporal distance may, in the end, be misleading. This will enable us to recognize that the notion of distance will, finally, have to yield its prerogatives to that of the notion of function. Historical writing is functionalist in the sense that the historical text is a substitute for the past discussed in it. That is its function. Hence the essay's title. (shrink)

The documentary film is a popular curriculum tool, and the goal of this paper is to expand the educational significance of the documentary genre I argue that current understandings of this genre are limited and limiting, and offer an alternative perspective on the genre. This alternative will be built from Stanley Cavell’s philosophy of education, in particular, his understanding of the role that ‘representativeness’ plays in teaching and learning.

Somatic mutation plays a key role in transforming normal cells into cancerous cells. The analysis of cancer progression therefore requires the study of how point mutations and chromosomal mutations accumulate in cellular lineages. The spread of somatic mutations depends on the mutation rate, the number of cell divisions in the history of a cellular lineage, and the nature of competition between different cellular lineages. We consider how various aspects of tissue architecture and cellular competition affect the pace of mutation accumulation. (...) We also discuss the rise and fall of somatic mutation rates during cancer progression. BioEssays 26:291–299, 2004. © 2004 Wiley Periodicals, Inc. (shrink)

The rule of law is a valuable human achievement. It is valuable not only instrumentally, but also for its own sake as a significant aspect of social justice. Only in a society that enjoys the rule of law is it possible for people to regard one another as fellow free citizens; no one the master of anyone else. Nevertheless, the rule of law is poorly understood. In this book, Frank Lovett develops a rigorous conception of the rule of law (...) that is grounded in legal positivism, and offers a civic republican argument for its value in terms of freedom from domination. Bridging persistent methodological gaps that divide legal philosophy, social science, and political theory, Lovett demonstrates how insights from all three can be united in a single powerful theory. This book will appeal to anyone interested in the rule of law, including scholars, legal officials, and policy-makers. (shrink)

Central to the thought of C.B. Macpherson are his critique of the culture of ‘possessive individualism’ and his defence of liberal-democratic socialism. Resurgence of interest in his works is in reaction to the rise of neoliberalism and efforts to find an alternative to societies dominated by capitalist markets. Macpherson’s theories are explained and applied to 21st century challenges.

In the standard formulation of game theory, agents use mixed strategies in the form of objective and probabilistically precise devices to conceal their actions. We introduce the larger set of probabilistically imprecise devices and study the consequences for the basic results on normal form games. While Nash equilibria remain equilibria in the extended game, there arise new Ellsberg equilibria with distinct outcomes, as we illustrate by negotiation games with three players. We characterize Ellsberg equilibria in two-person conflict and coordination games. (...) These equilibria turn out to be related to experimental deviations from Nash equilibrium play. (shrink)

The COVID-19 pandemic created a situation for the implementation of emergency remote learning. This meant that as a lecturer at a traditionalist University of contact sessions, the pandemic forced us to teach remotely through online methods of communication, using online lectures, narrated powerpoints, voice clips, podcasts, interviews and interactive videos. The assessments were conducted online from assignments to multiple choice questions, which forced the lecturers to think differently about the way the assessments were presented, in order to avoid easy access (...) to answers found in a textbook and online. This meant that more application questions of theory to practice were assessed in a more challenging way to prevent cheating and collaboration with peers. Formal assessments completed during emergency remote learning, have become the past practice, as innovative methods have been adopted for learning and for assessment purposes in order to preserve the integrity and attainment of the degree through online modes of learning. The aim of the paper investigates and explores the methods of teaching, together with the results obtained from the students of 2019 and 2020 in their final year relating to two final year modules against the literature relating to learning processes and methodologies.

Whether it is a question of apprehension, grasp, or simple contact, the vocabulary of perception clearly points towards the materiality of touch through what we usually think of as just a metaphorical variation. This is what ancient Greek thought recognized, or dimly felt, as a sometimes hidden constant in its history and its project: sensation, which describes the primary access to being, is first of all and above all a way of touching. Far from indicating a simple perceptual realism, this (...) acknowledgement implies a specific idea about the presence of things in the world: touch assumes a surface, and every being, in order to appear and be seen, must therefore be entirely surface, be articulated within a boundary that describes it perfectly.

The ethics of telling stories about other people become questionable as soon as humans learn to talk. But the stakes get higher when health care professionals tell stories about those whom they serve. But for all the problems that come with such stories, I do not believe it is either practical or desirable for bioethicists to attempt to legislate an end to this storytelling. What we need instead is narrative nuance. We need to understand how to tell respectful stories in (...) which the patients are fully acknowledged fellow participants, not one‐dimensional objects of a knowing gaze. The problem is not narration itself but a particular version of narrational privilege, and getting rid of that would have benefits far beyond practices of writing case studies. In this essay, I first offer four considerations that I have found either omitted or underemphasized in discussions of the ethics of telling stories about patients. I then sketch a model of medical storytelling that might be the basis for shifting the ethical question from whether to how. (shrink)

This article examines a contemporary proposal of how to conceive of materialism, more specifically of a materialist dialectics. This proposal was formulated by Alain Badiou and it is of huge interest for the contemporary discussion as it inscribes the very historical coordinates in which it was articulated into its own proposal. The article develops this by arguing that Badiou's materialist dialectic historically situates itself after idealist options seem to have become impossible. However, the very dialectical kernel of this materialism leads (...) Badiou to claim that after the perpetuated struggle between materialism and idealism is declared to have been overcome, the very split separating the two returns in an inverted form inside materialism, splitting it again into two. Thereby the immanent split in materialism leads to two options: either one defends a materialism devoid of any idealist reference or a materialism which seeks to rescue something of idealism. The article concludes by suggesting that only from a detailed reconstruction of the functioning of philosophy in Badiou's system does it become possible to conceive of the threats that any materialism today faces and to delineate the proposed option of how to avoid them consistently. The article demonstrates how, today, materialism can only be properly materialist by resurrecting something of idealism, which is why it deserves the name of what I call an “idealism without idealism.”.
