Tracking theories of knowledge are widely known to have the consequence that knowledge is not closed. Recent arguments by Vogel and Hawthorne claim both that there are no legitimate examples of knowledge without closure and that the costs of theories that deny closure are too great. This paper considers the tracking theories of Dretske and Nozick and the arguments by Vogel and Hawthorne. We reject the arguments of Vogel and Hawthorne and evaluate the costs of closure denial for tracking theories (...) of knowledge. (shrink)

Philosophical interest in situated cognition has been focused most intensely on the claim that human cognitive processes extend from the brain into the tools humans use. As we see it, this radical hypothesis is sustained by two kinds of mistakes, confusing coupling relations with constitutive relations and an inattention to the mark of the cognitive. Here we wish to draw attention to these mistakes and show just how pervasive they are. That is, for all that the radical philosophers have said, (...) the mind is still in the head. (shrink)

Much of contemporary epistemology proceeds on the assumption that tracking theories of knowledge, such as those of Dretske and Nozick, are dead. The word on the street is that Kripke and others killed these theories with their counterexamples, and that epistemology must move in a new direction as a result. In this paper we defend the tracking theories against purportedly deadly objections. We detect life in the tracking theories, despite what we perceive to be a premature burial.

What are the meanings of empty names such as ‘Vulcan,’ ‘Pegasus,’ and ‘Santa Claus’ in such sentences as ‘Vulcan is the tenth planet,’ ‘Pegasus flies,’ and especially ‘Santa Claus does not exist’?Our view, developed in Adams et al., consists of a direct-reference account of the meaning of empty names in combination with a pragmatic-implicature account of why we have certain intuitions that seem to conflict with a direct-reference account.

Sven Bernecker develops a theory of propositional memory that is at odds with the received epistemic theory of memory. On Bernecker’s account the belief that is remembered must be true, but it need not constitute knowledge, nor even have been true at the time it was acquired. I examine his reasons for thinking the epistemic theory of memory is false and mount a defense of the epistemic theory.

In a recent paper, Tristan Haze offers two examples that, he claims, are counterexamples to Nozick's Theory of Knowledge. Haze claims his examples work against Nozick's theory understood as relativized to belief forming methods M. We believe that they fail to be counterexamples to Nozick's theory. Since he aims the examples at tracking theories generally, we will also explain why they are not counterexamples to Dretske's Conclusive Reasons Theory of Knowledge.

In 2002, Luciano Floridi published a paper called What is the Philosophy of Information?, where he argues for a new paradigm in philosophical research. To what extent should his proposal be accepted? Is the Philosophy of Information actually a new paradigm, in the Kuhninan sense, in Philosophy? Or is it only a new branch of Epistemology? In our discussion we will argue in defense of Floridi’s proposal. We believe that Philosophy of Information has the types of features had by other (...) areas already acknowledge as authentic in Philosophy. By way of an analogical argument we will argue that since Philosophy of Information has its own topics, method and problems it would be counter-intuitive not to accept it as a new philosophical area. To strengthen our position we present and discuss main topics of Philosophy of Information. (shrink)

By contributing a few hundred dollars to a charity like UNICEF, a prosperous person can ensure that fewer poor children die, and that more will live reasonably long, worthwhile lives. Even when knowing this, however, most people send nothing, and almost all of the rest send little. What is the moral status of this behavior? To such common cases of letting die, our untutored response is that, while it is not very good, neither is the conduct wrong. What is the (...) source of this lenient assessment? In this contentious new book, one of our leading philosophers argues that our intuitions about ethical cases are generated not by basic moral values, but by certain distracting psychological dispositions that all too often prevent us from reacting in accord with our commitments. Through a detailed look at how these tendencies operate, Unger shows that, on the good morality that we already accept, the fatally unhelpful behavior is monstrously wrong. By uncovering the eminently sensible ethics that we've already embraced fully, and by confronting us with empirical facts and with easily followed instructions for lessening serious suffering appropriately and effectively, Unger's book points the way to a compassionate new moral philosophy.

The reflexive character of enactive theory is spelled out, in an effort to make explicit that which is usually implicit in debate: that we are responsible for the distinctions we draw, and that ultimately, the world that we collectively characterize is a joint production. Enaction, as treated here, is not a positivist scientific field, but an epistemologically self-conscious way to ground our understanding of the value-saturated lives of embodied beings. This stance is seen as entirely congruent with the scientific field (...) of ecological psychology, which is itself then cast as a specific example of the kind of science that can be done in an enactive mode.

Abstract: Luciano Floridi has impressively applied the concept of information to problems in semantics and epistemology, among other areas. In this essay, I briefly review two areas where I think one may usefully raise questions about some of Floridi's conclusions. One area is in the project to naturalize semantics and Floridi's use of the derived versus nonderived notion of semantic content. The other area is in the logic of information and knowledge and whether knowledge based on information necessarily supports closure, (...) in every instance. I suggest that it does not and, thereby, raise a challenge to Floridi's logic of being informed. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:L'autorité d'un canon philosophique. Le cas Descartes by Delphine Antoine-MahutFred AblondiDelphine Antoine-Mahut. L'autorité d'un canon philosophique. Le cas Descartes. Paris: Librairie Philosophique J. Vrin, 2021. Pp. 356. Paperback, €13.00.Henri Gouhier once asked, "Après le mort de Descartes, qu'est-ce que le cartésianisme?" to which he replied, "C'est la philosophie de Descartes vue par ses disciples" (La vocation de Malebranche [Paris: J. Vrin, 1926], 80). In L'autorité d'un canon philosophique, (...) Delphine Antoine-Mahut asks a similar question about who controls in just what a philosophical '-ism' consists, and she offers a nuanced and thoughtful answer. While "l'auctorialité du nom en question" is one part, she adds that we must also consider "l'auctorialité de celui ou de celle qui raconte cette histoire, dans un contexte et avec des enjeux très différent de ceux de l'individu d'origine auquel cette histoire est attachée" (10–11). The end result is that "un canon philosophique n'a rien de philosophiquement pur" (12). With this larger question in mind, she documents, as something of a case study, the genesis and development of the "impure" canon cartésien.The battle for authority over the content of canonical Cartesianism starts with the story of Descartes and his one-time devoted pupil and later disavowed outcast, Henricus Regius. Their relationship began in 1638, when Regius, a professor of theoretical medicine and botany at the University of Utrecht, wrote a letter of appreciation to Descartes. Over the next few years, Descartes offered both corrections to Regius's written work and advice on how best to handle the controversies that arose as a result of those writings. In 1645, however, Regius published his Fundamenta physices, in which he claimed that reason alone is not sufficient to prove either the existence of God or the real distinction between the human mind and body. In fact, he went on to speculate that the human mind is merely a mode of the body. [End Page 322] He also denied that we possess innate ideas, and the existence in us of a pure intellect. At the bottom of Regius's break with Descartes was his belief that Cartesian metaphysics is not needed to ground Cartesian physics. For Regius, consistency with empirical findings and simplicity are all that is required.At this point, as Antoine-Mahut puts it, "le sillon est creusé" (41). Descartes responded angrily, both in private letters and in his preface to the 1647 French edition of his Principles of Philosophy. He accused Regius of plagiarizing from his unpublished work and of confusing his views. Following the appearance of a broadsheet summarizing Regius's disagreements with Descartes (written by Regius's student, Peter Wassenaer), Descartes wrote Notae in programma quoddam, in which he reiterated his arguments for both God's existence and the real distinction. Regius and Wassenaer replied with their Brevis explicatio mentis humanae (1648). All of this is laid out clearly and in detail by Antoine-Mahut in part 1 of her book.Part 2 picks up with Descartes's literary executor Claude Clerselier and his campaign to disassociate Regius from what he believed to be "true" Cartesianism. In the preface to the publication of the first volume of Descartes's letters (1657), Clerselier revived the charge of plagiarism against Regius, who responded by publishing a second edition of the Brevis explicatio. This included a preface that attacked Clerselier for publishing Regius's private correspondence without his permission—in fact, because Regius had not made Descartes's letters to him available, Clerselier had had to reconstruct them from Descartes's notes— and claimed it was Descartes who plagiarized Regius. In Antoine-Mahut's narrative of these events, this "disassociation" was followed by a "combining" (her terms) of Cartesian thought with empiricist natural philosophy in the work of Louis de la Forge, for whom "le cartésianisme se spécifie comme une psychologie empiriste dans laquelle l'activité de l'âme joue un rôle essentiel" (175). There was then a subsequent "incorporating" (again borrowing Antoine-Mahut's terminology) by Nicolas Malebranche, who, she says, "occupe une place... (shrink)

Addis (1981) has criticized a proposal of ours (Wilson [1969b]) for analysing disposition predications in terns of the horseshoe of material implication, and has proposed a related but significantly different analysis. This paper restates the original proposal, and defends it against Addis's criticisms. It is further argued that his proposal will not do as a general account of disposition predications; that, however, if it is suitably qualified, then it does account for certain special sorts of disposition predication; but that so (...) understood, it can be seen to be but a special case of ours.

The barn/barn façade thought experiment is familiar to most epistemologists. It is intended to present a counterexample to certain causal theories of knowledge; in it, a father driving through the countryside with his son says, ‘That's a barn’ while pointing to a barn. Unbeknownst to the father, however, a film crew is working in the area, and it has constructed several barn façades. While the father did correctly point to a barn when he made his assertion, he could have just (...) as easily pointed to a barn façade, and so, many hold, he does not know that the structure at which he is pointing is in fact a barn. If this is so, then it follows that true beliefs formed from reliable causal processes may still not qualify as knowledge. (shrink)

In that it holds God to be the only true efficient cause, Malebranche’s occasionalism would seem to deny human freedom and to make God responsible for our sins. I argue that Malebranche’s occasionalism must be considered within its Cartesian framework; once one understands what it is to be an occasional cause in this context, Malebranche can be seen as saving a place for human freedom, and he can consistently hold that we are morally responsible for our actions.

This book consists of an edited collection of original essays of the highest academic quality by seasoned experts in their fields of cognitive science. The essays are interdisciplinary, drawing from many of the fields known collectively as “the cognitive sciences.” Topics discussed represent a significant cross-section of the most current and interesting issues in cognitive science. Specific topics include matters regarding machine learning and cognitive architecture, the nature of cognitive content, the relationship of information to cognition, the role of language (...) and communication in cognition, the nature of embodied cognition, selective topics in visual cognition, brain connectivity, computation and simulation, social and technological issues within the cognitive sciences, and significant issues in the history of neuroscience. This book will be of interest to both professional researchers and newer students and graduate students in the fields of cognitive science—including computer science, linguistics, philosophy, psychology and neuroscience. The essays are in English and are designed to be as free as possible of technical jargon and therefore accessible to young scholars and to scholars who are new to the cognitive neurosciences. In addition to several entries by single authors, the book contains several interesting roundtables where researchers contribute answers to a central question presented to those in the focus group on one of the core areas listed above. This exciting approach provides a variety of perspectives from across disciplines on topics of current concern in the cognitive sciences. (shrink)

In 1996, the U.S. Congress passed the Personal Responsibility and Work Opportunities Reconciliation Act that ended the entitlement of poor families to government assistance. The debate leading up to that transformation in welfare policy occurred in the shadow of Speenhamland—an episode in English Poor Law history. This article revisits the Speenhamland episode to unravel its tangled history. Drawing on four decades of recent scholarship, the authors show that Speenhamland policies could not have had the consequences that have been attributed to (...) them. The article ends with an alternative narrative that seeks to explain how the Speenhamland story became so deeply entrenched. (shrink)

"This anthology of writings by prominent black thinkers from antiquity to the present makes the case for a central tradition of black philosophy, rooted in Africa and distinct from the intellectual heritage of the West."--From publisher description.

In two recent books, Jerry Fodor has developed a set of sufficient conditions for an object “X” to non-naturally and non-derivatively mean X. In an earlier paper we presented three reasons for thinking Fodor's theory to be inadequate. One of these problems we have dubbed the “Pathologies Problem”. In response to queries concerning the relationship between the Pathologies Problem and what Fodor calls “Block's Problem”, we argue that, while Block's Problem does not threatenFodor's view, the Pathologies Problem does.

We consider two categorical syllogisms, valid or invalid, to be equivalent if they can be transformed into each other by certain transformations, going back to Aristotle, that preserve validity. It is shown that two syllogisms are equivalent if and only if they have the same models. Counts are obtained for the number of syllogisms in each equivalence class. For a more natural development, using group-theoretic methods, the space of syllogisms is enlarged to include nonstandard syllogisms, and various groups of transformations (...) on that space are studied.

Hans Hahn, mathematician, philosopher and co-founder of the Vienna Circle, attempted to reconcile the validity and applicability of both logic and mathematics with a strict empiricism. This article begins with a review of this attempt, focusing on his view of the relation of language to logic and his answer to the question of why we need logic. I then turn to some recent work by Stephen Yablo in an attempt to show that Yablo's fictionalism, and in particular his use of (...) metaphor, can shed light on Hahn's philosophy of logic. (shrink)

In the first thirty years after World War II, the US economy performed very well. The rate of growth averaged 4—5%, the rate of unemployment was seldom above 5%, inflation was almost non-existent, and the living standards of workers improved steadily. These were the ‘good old days'. However, this long period of expansion and prosperity ended in the 1970s. Since then, both the rate of unemployment and the rate of inflation have been much higher than before, and the average real (...) wages of workers have declined some 20%. Productivity growth has also slowed down and the debt burden of both capitalist enterprises and the Federal government has increased dramatically. It is in this sense that we may refer to the ‘economic crisis’ of the US economy over the last two decades. This crisis has certainly not been as severe as the Great Depression of the 1930s, but the economic performance has been significantly worse than in the early post-war period. (shrink)

We show that strong measure zero sets -totally bounded metric space) can be characterized by the nonexistence of a winning strategy in a certain infinite game. We use this characterization to give a proof of the well known fact, originally conjectured by K. Prikry, that every dense \ subset of the real line contains a translate of every strong measure zero set. We also derive a related result which answers a question of J. Fickett.

There are shown to many ε-Hermitian spaces, and an isometry criterion is stated which holds under MA ℵ 1 and is false under $2^{\aleph_0}.
