COnstantien Sandis speaks to Nassim Taleb about inductive knowledge,black swans, Hume, Popper, and Wittgenstein.

Vann McGee has recently argued that Belnap’s criteria constrain the formal rules of classical natural deduction to uniquely determine the semantic values of the propositional logical connectives and quantifiers if the rules are taken to be open-ended, i.e., if they are truth-preserving within any mathematically possible extension of the original language. The main assumption of his argument is that for any class of models there is a mathematically possible language in which there is a sentence true in just those models. (...) I show that this assumption does not hold for the class of models of classical propositional logic. In particular, I show that the existence of non-normal models for negation undermines McGee’s argument. (shrink)

Interview with Constantine Sigov, dedicated to the history of the "European Dictionary of Philosophies": from the emergence of an idea in the early 90's in France until the accomplishment of the Ukrainian edition in 2019.

A number of well-developed theories shed light on the question, under what circumstances our beliefs enjoy epistemic justification. Yet, comparatively little is known about epistemic defeat--when new information causes the loss of epistemic justification. This book proposes and defends a detailed account of epistemic defeaters. The main kinds of defeaters are analyzed in detail and integrated into a general framework that aims to explain how beliefs lose justification. It is argued that defeaters introduce incompatibilities into a noetic system and thereby (...) prompt a structured re-evaluation process that makes a justified reinstatement of the defeated belief impossible. The account is then applied to the topic of disagreement, where it is used in an argument for conciliationism, as well as a new explanation for higher-order defeat. Throughout the book, the notion of defeat is the center of attention, while a number of new issues are discussed at the intersections of defeat and justification. Specifically, new problems are raised for broadly internalist accounts of defeat, a fully descriptive reliabilist account of defeat is provided, and the case for normative defeat is revisited.

This paper documents a conversation between a philosopher and a human computer interaction researcher whose research has been enormously influenced by Wittgenstein. In particular, the in vivo use of categories in the design of communications and AI technologies are discussed, and how this meaning needs to evolve to allow creative design to flourish. The paper will be of interest to anyone concerned with philosophical tools in everyday action.

The Things We Do and Why We Do Them argues against the common assumption that there is a kind of thing called "action" which all reason-giving explanation of action are geared towards. Sandis explains why all theories concerned with the form which any such explanation must take fail from the outset, and shows how various debates on the nature of so-called motivating reasons only arise because the participants all share a number of mistaken views which follow from the basic assumption (...) under attack. In so doing, he urges philosophers and psychologists alike to stop asking whether the explanation of action is causal, and to focus instead on its multifarious objects. This book will appeal to anyone interested in motivational psychology, the reasons for which we act, and the philosophy of explanation in general. (shrink)

Is knowledge-how, or “practical” knowledge, a species of knowledge-that, or “theoretical” knowledge? There is no comfortable position to take in the debate around this question. On the one hand, there are counterexamples against the anti-intellectualist thesis that practical knowledge is best analysed as an ability. They show that having an ability to ϕ is not necessary for knowing how to ϕ. On the other hand, the intellectualist analysis of practical knowledge as a subspecies of theoretical knowledge is threatened by its (...) own set of counterexamples, which convincingly establish that practical knowledge lacks many of the typical characteristics of theoretical knowledge. Most strikingly it does not even appear to require a belief. In this paper, I develop an account of practical knowledge that avoids these counterexamples. It also manages to preserve both the status of such knowledge as a cognitive achievement and its apparently close conceptual relation to abilities. I start with the counterexamples against the necessity of abilities for practical knowledge and show that they fail because they underestimate the cognitive demands of attempts. I then make use of the logic of dispositions to bridge the gap that counterexamples against the necessity of abilities for practical knowledge open. It is argued that, instead of the ability to ϕ, it is a specific disposition to have the ability to ϕ that constitutes practical knowledge about ϕ. The resulting theory is an anti-intellectualist position that preserves essential intellectualist motivations and thus should be satisfactory for proponents of both views. (shrink)

We raise issues about the philosophical claims made in this article regarding the nature of nostalgia. Drawing on psychological research, we contend that nostalgia is rooted in memory rather than time, is directed toward specific objects rather than being object-free, is predominantly positive rather than a form of mourning, and is focused on the past rather than the present or future.

After several decades during which formalization has flourished it now becomes possible to detect its shortcomings. A definition of formalization is given at the outset. It is next shown that the main justification of formalization as making explicit the form of a proof has serious difficulties. An important shortcoming is found in the fact that many validation procedures in logic and mathematics are not adequately represented deductively. Several such procedures relating to the validation of logical and mathematical sentences are examined. (...) It is concluded that formalization is materially inadequate. (shrink)

Deleuze and Philosophy provides an exploration of the continuing philosophical relevance of Gilles Deleuze. This collection of essays uses Deleuze to move between thinkers such as Plato, Aristotle, Husserl, Hume, Locke, Kant, Foucault, Badiou and Agamben. As such the reader is left with a comprehensive understanding not just of the philosophy of Deleuze but how he can be situated within a much broader philosophical trajectory. Constantin Boundas has gathered together recent scholarship on Deleuze's philosophy by an acclaimed line-up of international (...) contributors, all of whom seek to provide new and previously unexplored theoretical terrains that will be of interest to both the Deleuze specialist and student alike. Three of the essays are by key French Deleuzians whose work is not widely available in translation. This enticing collection is essential reading for anyone interested not just in Deleuze but in the history of philosophical ideas. Contributors include: Zsuzsa Baross, Veronique Bergen, Ronald Bogue, Bruce Baugh, Rosi Braidotti, Claire Colebrook, Bela Egyed, Philippe Mengue, Dorothea Olkowski, Davide Panagia, Daniel W. Smith, Jeremie Valentin, Arnaud Villani. (shrink)

This paper argues that there was considerably more philosophy of action in moral theory before 1958 (when Anscombe complained of its lack under the banner 'philosophy of psychology') than there has been since. This is in part because Anscombe influenced the formation of 'virtue theory' as yet another position within normative ethics, and her work contributed to the fashioning of 'moral psychology' as an altogether distinct (and now increasingly empirical) branch of moral philosophy.

The question whether quantum discontinuity can or cannot provide an answer to Zeno's Paradoxes is reopened. It is observed that what is usually understood by the term "discontinuity", namely, Einstein's conception of the photon as described by himself and all others, is unsuitable to the task because, essentially,it reduces to the trivial 'discontinuity' of objects scattered in space. By contrast, quantization of energy levels, which are not in space but can only alternate in time, provide the right sort of discontinuity (...) required. Discrete quantized orbits, corresponding to eigen-frequencies, are irreducible, and nothing is allowed to stand in-between them in satisfaction of the quantum postulate, furnishing the requisite, and so far missing, immediate nextness of a point to a certain other. In this way, Zeno's Runner need not postpone his first step indefinitely, always waiting upon an infinity of preceding steps, before it can be taken. There is now a point that is next to a point and so a step on that point, which is the first step. It follows that, if one kind of discontinuity, Einstein's, is incapable of offerring an answer to Zeno, while another kind can, the two are discrepant. One of them, the former, is not a kind of discontinuity properly so called at all, though evidently the consequence of one. (shrink)

An important collection of essays providing a comprehensive overview of the thought of Gilles Deleuze, one of the most influential thinkers of the twentieth century.

Hinge Epistemology is rapidly becoming one of the most exciting areas of epistemology and Wittgenstein studies. In connecting these two fields it brings a revived energy to both, opening them up to fresh developments. The essays in this volume extend the subject in terms of both depth and breadth. They present new voices and challenges within hinge epistemology. They explore new applications and directions of hinge epistemology, particularly as it relates to the philosophy of mind, society, ethics, and the history (...) of ideas. (shrink)

The book is designed as an introduction to the basic questions of musical semantics and represents the quintessence of fifty years of the author's researches into music from Beethoven to Nono.

Wittgenstein teaches us that, contrary to current philosophical and scientific trends, the understanding of others is not to be achieved through some kind of emotional tool providing an access-pass to otherwise hidden ‘mental contents’. This insight goes against the popular grain of empathy as a form of informational ‘mindreading’, founded upon John Locke’s assumption that understanding another is a matter of obtaining and decoding the stored in their mind. We would do best to replace this radically distorted account of what (...) it takes to understand others with a stance that places priority on shared aspects of our lives. Only then can we even begin to try and tackle our moral, cultural, religious, and socio-political differences. (shrink)

In his first paper, ‘Must We Mean What We Say?’, Stanley Cavell defended the methods of ordinary language philosophy against various charges made by his senior colleague, Benson Mates, under the influence of the empirical semantics of Arne Naess.1Cavell’s argument hinges on the claim that native speakers are asourceof evidence for 'what is said' in language and, accordingly, need not base their claims about ordinary language upon evidence. In what follows, I maintain that this defence against empirical semantics applies equally (...) well to experimental philosophy's attack on doing philosophy from the armchair. In so doing, I attempt to clarify – and adjust – Cavell's claim that statements about ordinary language are rule‐descriptions that are neither analytic nor synthetic. (shrink)

Die Untersuchung stellt die Psychologie und Psychiatrie des jungen Kant vor, die im Rahmen seiner Auseinandersetzung mit dem schwedischen Gelehrten, Mystiker und Geisterseher Emanuel von Swedenborg entstanden ist. Hieraus ging Kants Wahnkritik hervor, in der er die drei Aspekte der Schizophrenie die Projektion, die Ich-Spaltung sowie die Paranoia analysiert. Constantin Rauer zeigt, dass und wie Kant seine fruhe Wahnkritik in die spatere Vernunftkritik ubertragen hat, und wie sich durch diese Anwendung der Psychologie auf die Logik das vollzog, was spater Kants (...) kritische Wende genannt wurde. Damit vollzieht der Autor erstmals Kants Revolution der Denkungsart und mit dieser die Genese seiner Kritik der reinen Vernunft systematisch nach. So fuhrt seine Untersuchung zu einem neuen Kant-Verstandnis, indem sie zeigt, dass Kants Vernunftkritik auch als eine Anti-Wahnkritik zu verstehen ist. Mit seiner Kritik des Wahns aber zielt Kant auf die verborgene Irrationalitat der Moderne: auf den erkenntnistheoretischen Wahn des Empirismus, den ethischen Wahn des Sozialdarwinismus sowie den religiosen Wahn im Kulturrelativismus. "Die Arbeit ist klar und uberzeugend aufgebaut. Uberdies ist sie sehr gut lesbar geschrieben: klar, zupackend, argumentativ, immer wieder von erhellenden Bildern durchsetzt; und die Verbindung einer wohldurchdachten Interpretation und Argumentation mit einer neuartigen These fuhrt zu einem philosophisch geradezu spannenden Text.... Hier findet eine hochentwickelte internationale Kantforschung einen grundlegend neuen Blick." ". (shrink)

Due to Gӧdel’s incompleteness results, the categoricity of a sufficiently rich mathematical theory and the semantic completeness of its underlying logic are two mutually exclusive ideals. For first- and second-order logics we obtain one of them with the cost of losing the other. In addition, in both these logics the rules of deduction for their quantifiers are non-categorical. In this paper I examine two recent arguments –Warren (2020), Murzi and Topey (2021)– for the idea that the natural deduction rules for (...) the first-order universal quantifier are categorical, i.e., they uniquely determine its semantic intended meaning. Both of them make use of McGee’s open-endedness requirement and the second one uses in addition Garson’s (2013) local models for defining the validity of these rules. I argue that the success of both these arguments is relative to their semantic or infinitary assumptions, which could be easily discharged if the introduction rule for the universal quantifier is taken to be an infinitary rule, i.e. non-compact. Consequently, I reconsider the use of the ω-rule and I show that the addition of the ω-rule to the standard formalizations of first-order logic is categorical. In addition, I argue that the open-endedness requirement does not make the first-order Peano Arithmetic categorical and I advance an argument for its categoricity based on the inferential conservativity requirement.

We establish the existence uncountably many atoms in the subvariety lattice of the variety of involutive residuated lattices. The proof utilizes a construction used in the proof of the corresponding result for residuated lattices and is based on the fact that every residuated lattice with greatest element can be associated in a canonical way with an involutive residuated lattice.
