In the early 1920s, the German mathematician David Hilbert (1862–1943) put forward a new proposal for the foundation of classical mathematics which has come to be known as Hilbert's Program. It calls for a formalization of all of mathematics in axiomatic form, together with a proof that this axiomatization of mathematics is consistent. The consistency proof itself was to be carried out using only what Hilbert called “finitary” methods. The special epistemological character of finitary reasoning then yields the required justification (...) of classical mathematics. Although Hilbert proposed his program in this form only in 1921, various facets of it are rooted in foundational work of his going back until around 1900, when he first pointed out the necessity of giving a direct consistency proof of analysis. Work on the program progressed significantly in the 1920s with contributions from logicians such as Paul Bernays, Wilhelm Ackermann, John von Neumann, and Jacques Herbrand. It was also a great influence on Kurt Gödel, whose work on the incompleteness theorems were motivated by Hilbert's Program. Gödel's work is generally taken to show that Hilbert's Program cannot be carried out. It has nevertheless continued to be an influential position in the philosophy of mathematics, and, starting with the work of Gerhard Gentzen in the 1930s, work on so-called Relativized Hilbert Programs have been central to the development of proof theory.

Angell's logic of analytic containment AC has been shown to be characterized by a 9-valued matrix NC by Ferguson, and by a 16-valued matrix by Fine. We show that the former is the image of a surjective homomorphism from the latter, i.e., an epimorphic image. The epimorphism was found with the help of MUltlog, which also provides a tableau calculus for NC extended by quantifiers that generalize conjunction and disjunction.

The ArgumentFocusing on the celebrations of Newton and his work, this article investigates the use of the concept of genius and its connection with debates on the methodology of science and the morality of great discoverers. During the period studied, two areas of tension developed. Firstly, eighteenth-century ideas about the relationship between genius and method were challenged by the notion of scientific genius as transcending specifiable rules of method. Secondly, assumptions about the nexus between intellectual and moral virtue were threatened (...) by the emerging conception of genius as marked by an extraordinary personality – on the one hand capable of breaking with established methods to achieve great discoveries, on the other, likely to transgress moral and social conventions. The assesments of Newton by nineteenth-century scientists such as Brewster, Whewell, and De Morgan were informed by these tensions. (shrink)

The essay focuses on the survival of Pascal’s metaphors concerning the cosmic wasteland. It analyzes step-by-step the ways in which authors such as Immanuel Kant, George Milbrey Gould, Herbert George Wells, Thomas Henry Huxley, Howard Phillips Lovecraft, Vladimír Hoppe, Jacques Monod, and Eugene Thacker appropriated Pascal’s images of despair from the “eternal silence of infinite spaces”, which they have then used to develop their own arguments in favor of defending (or disparaging) the relevance of a human presence in the universe. (...) The focus of the study lies in an analysis of these connections in the work of the Czech philosopher Vladimír Hoppe. (shrink)

The notion of a “query” occurred in legal, medical, theological and scientific writings during the early modern period. Whereas the “questionary” (from c. 1400s) sought replies from within a doctrine (such as Galenic medicine), in the 1600s the query posed open-ended inquiries, seeking empirical information from travellers, explorers and others. During the 1660s in Britain, three versions of the query (and lists of queries) emerged. Distinctions need to be made between queries seeking information via observation and those asking for experimentation, (...) and between those aiming to keep theory to one side and those that framed theoretical conjectures. My examples are drawn from the work of the Royal Society of London (founded 1660) and from some of its leading members, especially Robert Boyle, Robert Hooke and Isaac Newton. (shrink)

That India once had a sustained ‘dialogue’ with Scottish Philosophy is not gener- ally known, or that the exchange occurred in the medium of Sanskrit, not English. The essay explores an important cross-cultural encounter in the colonial context of mid 19th-century Benares where two Scots, John Muir and James Ballantyne, served as principals of a Sanskrit college established by the East India Company. Educated toward the end of the Scottish Enlightenment, they endeavoured to translate such distinctive concepts of ‘Scotch Metaphysics’ (...) as Externalism into Indian philosophical categories. The ensuing ‘dialogue’ with Brahmin interlocutors shows that the prob- lems they faced were less terminological than conceptual, having to do with contras- tive ways of understanding ‘mind’ and ‘man’. Between the two Scots, there were also signifi cant differences, although both had gone to India as Scottish Calvinists. While Muir remained largely impervious to Indian infl uence, Ballantyne was profoundly changed, becoming, in effect, a ‘Vedantic Calvinist’. (shrink)

"Younker delves into and illustrates every aspect of Putman's life: how he works, what he does to relax, how he interacts with family and friends. He shows how Putman fished, divulging some of the secrets of the professional fisherman. Examining this fisherman's life - as well as the lives of his relatives and friends - Younker demonstrates Putman's skill as colorful storyteller with a rich vocabulary. Putman proved forthright when expressing his views about life, river lore, and the changing ecology."--Jacket.

This study takes up the challenge presented to philosophy in a dramatic and urgent way by contemporary medicine: the phenomenon of human life. Initiated by a critical appreciation of the work of Hans Jonas, who poses that issue as well, the inquiry is brought to focus on the phenomenon of embodiment, using relevant medical writing to help elicit its concrete dimensions. The explication of embodiment, aided by critical studies and inquiries into medical phenomena make possible the development of the author’s (...) original phenomenological theory of self, and its concrete relationships with the other self. This study attempts not only to show connections among the works of a number of thinkers in terms of central problems, but to demonstrate the mutual relevance of medicine and philosophy through concrete illustrations and analysis.

Ultralogic as Universal? is a seminal text in non-classcial logic. Richard Routley presents a hugely ambitious program: to use an 'ultramodal' logic as a universal key, which opens, if rightly operated, all locks. It provides a canon for reasoning in every situation, including illogical, inconsistent and paradoxical ones, realized or not, possible or not. A universal logic, Routley argues, enables us to go where no other logic—especially not classical logic—can. Routley provides an expansive and singular vision of how a (...) universal logic might one day solve major problems in set theory, arithmetic, linguistics, physics, and more. It circulated in typescript in the late 1970s before appearing as the Appendix to Exploring Meinong's Jungle and Beyond. With engaging, forceful prose, unsparing criticism of entrenched institutions, and many tantalizing proof sketches, Ultralogic? has had a major influence on the development of paraconsistent and relevant logic. This new edition makes this work available for a modern audience, newly typeset and corrected, along with extensive notes, and new commentary essays. (shrink)

Rational agents are important objects of study in several research communities, including economics, philosophy, cognitive science, and most recently computer science and artificial intelligence. Crudely, a rational agent is an entity that is capable of acting on its environment, and which chooses to act in such a way as to further its own best interests. There has recently been much interest in the use of mathematical logic for developing formal theories of such agents. Such theories view agents as practical reasoning (...) systems, deciding moment by moment which action to perform next, given the beliefs they have about the world and their desires with respect to how they would like the world to be. In this article, we survey the state of the art in developing logical theories of rational agency. Following a discussion on the dimensions along which such theories can vary, we briefly survey the logical tools available in order to construct such theories. We then review and critically assess three of the best known theories of rational agency: Cohen and Levesque's intention logic, Rao and Georgeff's BDI logics, and the KARO framework of Meyer et al. We then discuss the various roles that such logics can play in helping us to engineer rational agents, and conclude with a discussion of open problems. (shrink)

It is commonly held that there is no place for the 'now’ in physics, and also that the passing of time is something subjective, having to do with the way reality is experienced but not with the way reality is. Indeed, the majority of modern theoretical physicists and philosophers of physics contend that the passing of time is incompatible with modern physical theory, and excluded in a fundamental description of physical reality. This book provides a forceful rebuttal of such claims. (...) In successive chapters the author explains the historical precedents of the modern opposition to time flow, giving careful expositions of matters relevant to becoming in classical physics, the special and general theories of relativity, and quantum theory, without presupposing prior expertise in these subjects. Analysing the arguments of thinkers ranging from Aristotle, Russell, and Bergson to the proponents of quantum gravity, he contends that the passage of time, understood as a local becoming of events out of those in their past at varying rates, is not only compatible with the theories of modern physics, but implicit in them.

When the assertion that some agent is exploiting a person connotes that the exploitation is morally wrong, what is this wrong? Some maintain that exploitation need not involve unfair division of advantages, but instead is essentially domination for self-enrichment. This essay denies this claim and upholds the idea that exploitation claims concern unfair distribution. Some maintain that the hypothetical fully competitive market exchange price can serve, at least in some contexts, as the standard for assessing whether voluntary interaction is exploitative. (...) This essay denies that the idea of the fully competitive market price can serve in this role. Nor should we accept a pure luck egalitarian claim that would identify fair distribution with the outcome of ideally competitive markets proceeding from fair initial distribution. (shrink)

Would a just society or government absolutely refrain from shaming or humiliating any of its members? "No," says this essay. It describes morally acceptable uses of shame, stigma and disgust as tools of social control in a decent (just) society. These uses involve criminal law, tort law, and informal social norms. The standard of moral acceptability proposed for determining the line is a version of perfectionistic prioritarian consequenstialism. From this standpoint, criticism is developed against Martha Nussbaum's view that to respect (...) the dignity of each person, society absolutely must refrain from certain ways of shaming and humiliating its members and rendering them objects of communal disgust.

Richard Bett presents a ground-breaking study of Pyrrho of Elis, who lived in the late fourth and early third centuries BC and is the supposed originator of Greek scepticism. In the absence of surviving works by Pyrrho, scholars have tended to treat his thought as essentially the same as the long subsequent sceptical tradition which styled itself 'Pyrrhonism'. Bett argues, on the contrary, that Pyrrho's philosophy was significantly different from this later tradition, and offers the first detailed account of (...) that philosophy in this light. Bett considers why Pyrrho was adopted as the figurehead for that tradition: his answer suggests that we should distinguish two phases within Pyrrhonism, of which the initial phase is much closer to Pyrrho's own thought than is the better-known later phase. Bett also investigates the origins and antecedents of Pyrrho's ideas; in particular, Plato is singled out as an important inspiration. The result is the first comprehensive picture of this key figure in the development of philosophy. The new claims that Bett puts forward have major implications for the history and interpretation of ancient Greek thought. (shrink)

Many have been attracted to the idea that for something to be good there just have to be reasons to favour it. This view has come to be known as the buck-passing account of value. According to this account, for pleasure to be good there need to be reasons for us to desire and pursue it. Likewise for liberty and equality to be values there have to be reasons for us to promote and preserve them. Extensive discussion has focussed on (...) some of the problems that the buck-passing account faces, such as the 'wrong kind of reason' problem. Less attention, however, has been paid as to why we should accept the buck-passing account or what the theoretical pay-offs and other implications of accepting it are. The Normative and the Evaluative provides the first comprehensive0motivation and defence of the buck-passing account of value. Richard Rowland argues that the buck-passing account explains several important features of the relationship between reasons and value, as well as the relationship between the different varieties of value, in a way that its competitors do not. He shows that alternatives to the buck-passing account are inconsistent with important views in normative ethics, uninformative, and at odds with the way in which we should see practical and0epistemic normativity as related. In addition, he extends the buck-passing account to provide an account of moral properties as well as all other normative and deontic properties and concepts, such as fittingness and 'ought', in terms of reasons.

This research explores the role of emotions in goal-directed behaviour. A model is provided for an emotional goal system whereby appraisals of the consequences of achieving or not achieving a goal are hypothesised to elicit anticipatory emotions; the anticipatory emotions are expected, in turn, to contribute to volitions in the service of goal pursuit (namely, intentions, plans, and the decision to expend energy); goal-directed behaviours next arise in response to volitions and lead to goal attainment; and the latter then functions (...) as the basis for a new set of appraisals and accompanying goaloutcome emotions. The model was tested in a longitudinal study of the responses of 406 adults (243 women, 163 men) in The Netherlands. The context for the study was the regulation of one's bodyweight via exercising and dieting. (shrink)

In their celebrated essay “The Right to Privacy,” legal scholars Samuel Warren and Louis Brandeis identified as the generic privacy value “the right to be let alone.” This same phrase occurs in Justice Brandeis's dissent inOlmstead v. U.S.(1927). This characterization of privacy has been found objectionable by philosophers acting as conceptual police. For example, moral philosopher William Parent asserts that one can wrongfully fail to let another person alone in all sorts of ways—such as assault—that intuitively do not qualify as (...) violations of privacy and thus cannot be violations of the right to privacy.

Among Western philosophers, Schopenhauer is one of the few who seeks to clarify the nature of music, and its effects upon us. He claims that music is the most important of all the arts; and he argues that music is a kind of metaphysics that allows us to experience the ultimate reality of the world. In this essay, I evaluate Schopenhauer’s philosophy of music in the context of his overarching philosophy. Then I discuss the relevance of traditional Indian philosophies -- (...) including Advaita Vedanta and Buddhism -- which Schopenhauer recognized as forerunners to his own philosophical system. Here, the discussion of Om is particularly important. Schopenhauer’s discussion of music is insightful. But his insistence on the priority of the will is problematic. I suggest another perspective on willing, ultimate reality and music which follows the classical Indian philosophies that he affirms. (shrink)

Does it make sense to hold that, if it is bad that some people are worse off than others, it is worse if those who are worse off come to be so through sheer bad luck that it is beyond their power to control? In her contribution to this symposium, Susan Hurley cautions against a closely related fallacy: from the fact that people have come to an unequal condition through unchosen bad luck, it does not follow that, if we aim (...) to undo the influence of unchosen luck, we ought to institute equality of condition. Forswearing the fallacy that Hurley analyses is compatible with answering the question affirmatively, and more generally with holding that principles of distributive justice should be sensitive to the distinction between chosen and unchosen bad luck. This essay explores how this might be done. (shrink)

McCarthy thinks truth more important than I do. Specifically, he thinks that “ ‘truth’ … functions as an ‘idea of reason’ with respect to which we can criticize not only particular claims within our language but the very standards of truth we have inherited” . By contrast, I think that what enables us to make such criticism is concrete alternative suggestions—suggestions about how to redescribe what we are talking about. Some examples are Galileo’s suggestions about how to redescribe the Aristotelian (...) universe, Marx’s suggestions about how to redescribe the nineteenth century, Heidegger’s suggestions about how to redescribe the West as a whole, Dickens’s suggestions about how to redescribe chancery law, Rabelais’s suggestions about how to redescriibe monasteries, and Virginia Woolf’s suggestions about how to redescribe women writing.Such fresh descriptions, such new suggestions of things to say, sentences to consider, vocabularies to employ, are what do the work. All that the idea of truth does is to say, “Bethink yourself that you might be mistaken; remember that your beliefs may be justified by your other belies in the area, but that the whole kit and caboodle might be misguided, and in particular that you might be using the wrong words for your purpose.” But this admonition is empty and powerless without some concrete suggestion of an alternative set of beliefs, or of words. Moreover, if you have such a suggestion, you do not need the admonition. The only cash value of this regulative idea is to commend fallibilism, to remind us that lots of people have been as certain of, and as justified in believing, things that turned out to be false as we are certain of, and justified in holding, our present views. It is not, as McCarthy says, a “moment of unconditionality that opens us up to criticism from other points of view” . It is the particular attractions of those other points of view.Richard Rorty is University Professor of Humanities at the University of Virginia.

This important new study is an intellectual history exploring the reception of Darwinism by prominent German socialist theoriests: Karl Marx, Friedrich Engles, Friedrich Albert Lange, Ludwig B chner, August Bebel, Karl Katusky, and Eduard Bernstein. It relies not only on published books, articles, and speeches by these men, but also on some unpublished correspondence. In addition, one chapter covers the anti-socialist stance of prominent Darwinian biologists, including Charles Darwin and the foremost champion of Darwinism in Germany, Ernst Haeckel. Darwinism's effect (...) on German socialism's view of eugenics, race and religion are also discussed. (shrink)

A reciprocity framework is presented as an analysis of morality, and to explain and justify the attribution of moral rights and duties. To say an entity has rights makes sense only if that entity can fulfill reciprocal duties, i.e., can act as a moral agent. To be a moral agent an entity must (1) be self-conscious, (2) understand general principles, (3) have free will, (4) understand the given principles, (5) be physicallycapable of acting, and (6) intend to act according to (...) or against the given principles. This framework is foundational both to empirical and supernatural positions which distinguish a human milieu, which is moral, from a nonhuman milieu, which is not. It also provides a basis for evaluating four standard arguments for the rights ofnonhuman animals and nature-the ecological, the prudential, the sentimental, and the contractual. If reciprocity is taken as being central to the general concepts of rights and duties, then few animals, and no natural objects or natural systems, have rights and duties in an intrinsic or primary sense, although they may be assigned them in an extrinsic or secondary sense as a convenience in connection with human interests. Nevertheless, there are some animals besides humans - e.g., especially chimpanzees, gorillas, dolphins, and dogs - which, in accordance with good behavioral evidence, are moral entities, and sometimes moral agents. On the grounds of reciprocity, they merit, at aminimum, intrinsic or primary rights to life and to relief from unnecessary suffering. (shrink)

BackgroundResearchers conducting community-based participatory action research (CBPAR) in highly collectivistic and socioeconomically disadvantaged community settings in sub-Saharan Africa are confronted with the distinctive challenge of balancing universal ethical standards with local standards, where traditional customs or beliefs may conflict with regulatory requirements and ethical guidelines underlying the informed consent (IC) process. The unique ethnic, socioeconomic, and cultural diversities in these settings have important implications for the IC process, such as individual decisional autonomy, beneficence, confidentiality, and signing the IC document.Main textDrawing (...) on insights and field observations from conducting CBPARs across several rural, highly communal, low literate, and low-income communities in Ghana, we discuss some theoretical, ethico-cultural, and methodological challenges associated with applying the universal, Western individualistic cultural value-laden IC process in sub-Saharan Africa. By citing field situations, we discuss how local cultural customs and the socioeconomic adversities prevalent in these settings can influence (and disrupt) the information disclosure process, individual decisional authority for consent, and voluntariness. We review the theoretical assumptions of the Declaration of Helsinki’s statement on IC and discuss its limitations as an ultimate guide for the conduct of social science research in the highly communal African context. We argue that the IC process in these settings should include strategies directed at preventing deception and coercion, in addition to ensuring respect for individual autonomy. We urge Universities, research institutions, and institutional review boards in Africa to design and promote the use of context-appropriate ethical IC guidelines that take into consideration both the local customs and traditional practices of the people as well as the scientific principles underpinning the universal IC standards.ConclusionWe recommend that, rather than adopt a universal one-size-fits-all IC approach, researchers working in the rural, highly collectivistic, low literate, socioeconomically disadvantaged settings of sub-Saharan Africa should deeply consider the roles and influence of cultural values and traditional practices on the IC and the research process. We encourage researchers to collaborate with target communities and stakeholders in the design and implementation of context-appropriate IC to prevent ethics dumping and safeguard the integrity of the research process.

Contemporary epistemological and cognitive studies, as well as recent trends in computer science and game theory have revealed an increasingly important and intimate relationship between Information, Interaction, and Agency. Agents perform actions based on the available information and in the presence of other interacting agents. From this perspective Information, Interaction, and Agency neatly ties together classical themes like rationality, decision-making and belief revision with games, strategies and learning in a multi-agent setting. Unified by the central notions Information, Interaction, and Agency, (...) the essays in this volume provide refreshing methodological perspectives on belief revision, dynamic epistemic logic, von Neumann games, and evolutionary game theory; all of which in turn are central approaches to understanding our own rationality and that of other agents.

This volume concerns Rational Agents - humans, players in a game, software or institutions - which must decide the proper next action in an atmosphere of partial information and uncertainty. The book collects formal accounts of Uncertainty, Rationality and Agency, and also of their interaction.

The relation between humans and nature is at the core of the great existential threats of our time, from climate change, extreme weather, and environmental destruction to devastating pandemics. We are becoming increasingly aware of the fact that, unless we change our behavior radically and quickly, the most likely outcome will be the destruction of countless species and forms of life, including our own. But we also need to change the way we think about nature, and think about the relation (...) between humans and nature – this is a key intellectual task. In this important book, Richard J. Bernstein argues that an adequate conception of humans and nature, capable of facing up to the existential threats of our time, requires taking full account of the major projects dealing with nature in the past. Focusing on key figures of modernity – Spinoza, Hume, Kant, Hegel, Marx, Nietzsche, and Freud – Bernstein reconstructs their conceptions of nature and uncovers the reasons that led them to their distinctive views. Working through the contradictions and incompatibilities among these diverse thinkers, Bernstein identifies common themes that have shaped their struggles in dealing with the relation of humans to nature. He offers a critical overview of the challenges illuminated by each perspective that must be confronted in our thinking of nature today. As a prolegomenon to rethinking humanity and nature, this book uncovers the rich conceptual resources available within the modern tradition that can help us to develop an adequate understanding of nature for our time.
