1 (penultimate version; final version to appear in Proceedings and Addresses of the American Philosophical Association 2019) The 2019 Sanders Lecture Morally Loaded Cases in Philosophy1 Timothy Williamson 1. The question Dialectical effectiveness in philosophy can pattern in surprising ways. For instance, when apparently morally neutral issues are debated in epistemology and metaphysics, philosophical logic and philosophy of language, morally loaded examples sometimes have greater dialectical power than morally neutral examples based on knowledge from ordinary life or natural science. One might have expected it to be the other way round, given the contested status of moral knowledge. By ‘morally loaded’ I mean cases explicitly described in moral terms, or at least in ways which make moral matters very salient, as with Holocaust denial. Such cases seem to be so dialectically powerful because they are so highly emotive. That raises an obvious question: is this dialectical power legitimate, or does it involve a kind of cheating, getting readers or hearers worked up to a point where they are in no mood to apply subtle but necessary distinctions? We are usually supposed to be best at assessing philosophical claims in a cool hour. 2. Three classes of example Before addressing the main question, we should look more closely at the phenomenon to be understood. I will sketch three classes of philosophical view which seem vulnerable to such moralizing critiques. The list is far from exhaustive. Relativism 2 I have in mind full-blown relativism about truth, the idea that when you and I seem deadlocked in disagreement, the bottom line is that some things are true for me but not for you, while other things are true for you but not for me; there is no question of one of us being really or absolutely right and the other really or absolutely wrong. -
Aristotelian Finitism
Synthese DOI 10.1007/s11229-015-0827-9 S.I. : INFINITY Aristotelian finitism Tamer Nawar1 Received: 12 January 2014 / Accepted: 25 June 2015 © Springer Science+Business Media Dordrecht 2015 Abstract It is widely known that Aristotle rules out the existence of actual infinities but allows for potential infinities. However, precisely why Aristotle should deny the existence of actual infinities remains somewhat obscure and has received relatively little attention in the secondary literature. In this paper I investigate the motivations of Aristotle’s finitism and offer a careful examination of some of the arguments con- sidered by Aristotle both in favour of and against the existence of actual infinities. I argue that Aristotle has good reason to resist the traditional arguments offered in favour of the existence of the infinite and that, while there is a lacuna in his own ‘logi- cal’ arguments against actual infinities, his arguments against the existence of infinite magnitude and number are valid and more well grounded than commonly supposed. Keywords Aristotle · Aristotelian commentators · Infinity · Mathematics · Metaphysics 1 Introduction It is widely known that Aristotle embraced some sort of finitism and denied the exis- tence of so-called ‘actual infinities’ while allowing for the existence of ‘potential infinities’. It is difficult to overestimate the influence of Aristotle’s views on this score and the denial of the (actual) existence of infinities became a commonplace among philosophers for over two thousand years. However, the precise grounds for Aristo- tle’s finitism have not been discussed in much detail and, insofar as they have received attention, his reasons for ruling out the existence of (actual) infinities have often been B Tamer Nawar [email protected] 1 University of Oxford, 21 Millway Close, Oxford OX2 8BJ, UK 123 Synthese deemed obscure or ad hoc (e.g. -
Philosophical Knowledge and Knowledge of Counterfactuals
Grazer Philosophische Studien 74 (2007), 89–123. PHILOSOPHICAL KNOWLEDGE AND KNOWLEDGE OF COUNTERFACTUALS Timothy WILLIAMSON University of Oxford Summary Metaphysical modalities are defi nable from counterfactual conditionals, and the epistemology of the former is a special case of the epistemology of the latter. In particular, the role of conceivability and inconceivability in assessing claims of possibility and impossibility can be explained as a special case of the pervasive role of the imagination in assessing counterfactual conditionals, an account of which is sketched. Th us scepticism about metaphysical modality entails a more far-reaching scepticism about counterfactuals. Th e account is used to question the signifi cance of the distinction between a priori and a posteriori knowledge. § 0. Philosophers characteristically ask not just whether things are some way but whether they could have been otherwise. What could have been otherwise is metaphysically contingent; what could not is metaphysically necessary. We have some knowledge of such matters. We know that Henry VIII could have had more than six wives, but that three plus three could not have been more than six. So there should be an epistemology of metaphysical modality. Th e diff erences between metaphysical necessity, contingency and impos- sibility are not mind-dependent, in any useful sense of that tantalizing phrase. Th us they are not diff erences in actual or potential psychological, social, linguistic or even epistemic status (Kripke 1980 makes the crucial distinctions). One shortcut to this conclusion uses the plausible idea that mathematical truth is mind-independent. Since mathematics is not con- tingent, the diff erence between truth and falsity in mathematics is also the diff erence between necessity and impossibility; consequently, the diff erence between necessity and impossibility is mind-independent. -
Philosophy 539/Theory of Knowledge: Evidence
Philosophy 539/Theory of Knowledge: Evidence Princeton University Spring 2008 Wednesdays 1:30-4:20, Marx 201 An examination of select issues at the intersection of philosophy of science and epistemology, with a focus on the theme of ‘evidence’. Recent work on the concept of evidence, with some attention to both informal and formal approaches. Williamson’s conception of evidence as knowledge. Evidence and epistemic diversity. How should we think of evidence which bears on philosophical theories? (Is there some distinctive kind of ‘philosophical’ evidence, e.g., ‘intuitions’, or is such evidence ultimately of a piece with scientific evidence?) In what respects (if any) does common sense provide a kind of data for philosophy? The role of normative ideals for believers who have evidence of their own finitude and fallibility.

Knowledge As Evidence
Knowledge as Evidence TIMOTHY WILLIAMSON It is argued that a subject’s evidence consists of all and only the propositions that the subject knows. I Tradition has it that the main problems of philosophy include the nature of knowledge. But, in recent decades, questions of knowledge seem to have been marginalized by questions of justification. Thus, according to Crispin Wright, … knowledge is not really the proper central concern of episte- mologico-sceptical enquiry. […] We can live with the conces- sion that we do not, strictly, know some of the things we believed ourselves to know, provided we can retain the thought that we are fully justified in accepting them. (1991, p. 88; Wright’s italics) Similarly, John Earman argues that accounts of knowledge are irrelevant to the philosophy of science, because in it … the main concern is rarely whether or not a scientist “knows” that some theory is true but rather whether or not she is justified in believing it. (1993, p. 37)1 Once Gettier showed in 1963 that justified true belief is insufficient for knowledge, and therefore that knowledge is unnecessary for justified true belief, it became natural to ask: if you can have justified true beliefs, why bother with knowledge?2 There is a lacuna in the case for the unimportance of knowledge. Grant, for the sake of argument, that knowledge is important only if it is some- 1 Earman is discussing externalist accounts of knowledge, but the quoted com- ment would clearly apply to internalist accounts too. Earman’s further point, that “because science is a community enterprise the only forms of justification that are scientifically relevant are those which are stateable and open to public scrutiny”, may be most relevant to externalist accounts. -
Conceptual Analysis LPS 200 Fall 2012-Winter 2013
Conceptual Analysis LPS 200 Fall 2012-Winter 2013 In this course, we’ll examine various points of view on the idea of conceptual analysis -- once considered the only proper method for analytic philosophy. Along the way, some comparisons with other meta- philosophies may help illuminate our main subject. Toward the end, we’ll consider some recent alternative takes on what so-called ‘analytic philosophy’ is and how it should be done. (Lurking in the background throughout will be an austere form of naturalism that I call ‘Second Philosophy’. You might find it helpful to glance at the introductory paper ‘Second philosophy’ (available on my web site) or dip into Part I (and perhaps also section IV.1) of the book Second Philosophy.) The default requirement for those taking the course for a grade (other than S/U) is three short papers (750-1250 words) due at the beginning of class in the 4th week, 7th week, and 10th weeks. Each paper should isolate one localized point in the readings and offer some analysis and/or critique. (I’m happy to discuss topics and/or read drafts ahead of time, in by e-mail or in person.) Other options are open to negotiation. I assume everyone has access to copies of J. L. Austin, Philosophical Papers. Ludwig Wittgenstein, Tractatus Logico-Philosophicus. Ludwig Wittgenstein, Philosophical Investigations. Timothy Williamson, The Philosophy of Philosophy. The rest of the assigned readings are available to enrolled students on the course EEE web page. Please come to the first meeting prepared to discuss the reading in Topic 1. -
WHAT DO PHILOSOPHERS KNOW?1 Andrew MELNYK
Grazer Philosophische Studien 80 (2010), 297–307. WHAT DO PHILOSOPHERS KNOW?1 Andrew MELNYK University of Missouri In his new book, Timothy Williamson makes a frontal assault on the questions of what philosophy is, what sort of knowledge it can attain, and what methods it can and should use. He follows no familiar party line, and indeed has something to off end everyone2. In the book’s fi rst part, comprising chapters one through four, he works toward the conclusion that philosophy, unlike, say, astronomy, has no special subject matter, and that, in particular, “few philosophical ques- tions are conceptual questions in any distinctive sense, except when philosophers choose to ask questions about concepts” (Williamson 2007, 3). In the book’s second part, comprising chapters fi ve through eight, he makes a start on a new epistemology of philosophy, one intended to vindicate the view that the knowl- edge achieved and methods used in philosophy are no diff erent in kind from the knowledge achieved and methods used in everyday inquiry and in science. But he does not proceed, as perhaps one might have expected, by defending a thorough-going naturalism, according to which philosophy, being continuous with science, uses versions of scientifi c methods; he never has a good word for naturalism, and calls it “crude empiricism” (1-2). In an afterword, entitled “Must Do Better”, he urges philosophers to hold themselves to higher methodological standards and thus realize what he takes to be philosophy’s hitherto unrealized potential. (In the UK, “Must do better” used to be a stock phrase from end-of- term reports on the academic performance of schoolchildren.) Th e book ends with two formal appendices. -

On Williamson and Simplicity in Modal Logic∗ Theodore Sider Canadian Journal of Philosophy 46 (2016): 683–98
On Williamson and Simplicity in Modal Logic∗ Theodore Sider Canadian Journal of Philosophy 46 (2016): 683–98 According to Timothy Williamson, we should accept the simplest and most powerful second-order modal logic, and as a result accept an ontology of “bare possibilia”. This general method for extracting ontology from logic is salutary, but its application in this case depends on a questionable assumption: that modality is a fundamental feature of the world. 1. Necessitism The central thesis of Williamson’s wonderful book Modal Logic as Metaphysics is “Necessitism”. Put roughly and vividly, Necessitism says that everything neces- sarily exists. Williamson himself avoids the predicate ‘exists’, and formulates the view thus: Necessitism x2 y y = x (“Everything necessarily is something”) 8 9 Williamson’s scruples about ‘exists’ are reasonable but sometimes require tor- tured prose, so, choosing beauty over function, I will use the E-word. (But let it be understood that by “x exists” I just mean that x is identical to something— with quanti ers “wide open”.) The considerations favoring Necessitism also lead Williamson to accept the Barcan schema (as well as its converse): Barcan schema 3 xA x3A 9 ! 9 So if there could have been a child of Wittgenstein, then there in fact exists something that could have been a child of Wittgenstein. This thing that could have been a child of Wittgenstein: what is it like? What are its properties? Well, it has the modal property of possibly being a child of Wittgenstein. And logic demands that it have certain further properties, such as the property of being self-identical, the property of being green if it is green, and so forth. -
TIMOTHY WILLIAMSON Knowledge and Its Limits Oxford: Oxford University Press, 2000
This is a prepublication draft of a review that appears in its final and official form in The British Journal for the Philosophy of Science, 2002 TIMOTHY WILLIAMSON Knowledge and its Limits Oxford: Oxford University Press, 2000 Keith DeRose Department of Philosophy Yale University Though he’s perhaps best known for his work on vagueness, Timothy Williamson also produced a series of outstanding papers in epistemology in the late 1980's and the 1990's. Knowledge and its Limits brings this work together. The result is, in my opinion, the best book in epistemology to come out since 1975. Those familiar with Williamson’s articles will not find anything startlingly new here. Still, the book is not just a thinly disguised collection of old papers. Much of the material is significantly improved, with important new substantive points added. Beyond those new substantive contributions, Williamson does a good job of drawing his earlier work together into a coherent whole, both by means of explanations of the interconnections between his claims and arguments and by some rearrangement of material: Some of the old papers are broken up and interspersed with material from other papers. The resulting picture is rich and complicated, reaching into important regions of philosophy of mind and philosophy of language, in addition to epistemology, but in his Preface, Williamson volunteers: “If I had to summarize this book in two words, they would be: knowledge first” (p. v). A key to Williamson’s approach is that he does not take knowledge to be something to be analyzed, in anything like the traditional way, but something to be used in the elucidation of other concepts. -

On Williamson's New Quinean Argument Against
CORE Metadata, citation and similar papers at core.ac.uk Provided by Open Journal Systems at the Victoria University of Wellington Library Australasian Journal of Logic On Williamson's new Quinean argument against nonclassical logic Jc Beall entailments.net University of Connecticut Strange phenomena drive a lot of otherwise surprising features of system- atic theories, phenomena that buck the usual cases and demand an explana- tion that goes beyond the obvious norm. This is so not only in philosophy but in all cases of systematic truth-seeking theorizing, from science to theol- ogy. For present purposes, let truth-theoretic paradoxes (e.g., liars, etc.) be our paradigm of strange phenomena. In the face of such phenomena many have advanced an account according to which logic is nonclassical. Against such accounts W.V.O. Quine [36] famously argued from a principle of con- servatism (viz., minimal mutilation of current theory) and the premise that classical logic is the status quo to the conclusion that, because nonclassical logic appears to reduce (or at least not increase) explanatory power of many true theories (e.g., maths, physics, more), one should reject nonclassical-logic responses to strange phenomena. All of this (and more) is familiar. Also familiar is that Quine's argument, despite the valuable pragmatist methodology that drives it, is often seen to plainly fail as an argument against nonclassical-logic accounts of strange phenomena. Perhaps the biggest reason for the failure, setting aside his unfortunate charge of `changing the subject', is that Quine's argument precludes nonclassical logic from the get-go { the central premise claiming both that classical logic is the `status quo' and that conservatism in our methodology requires us to maintain the status quo (short of some resoundingly loud recalcitrant data that leaves no other option but to dive to the deeper depths of subclassical or otherwise nonclassical logic).
