(A) I went to the pictures last Tuesday but I don’t believe that I did (1942, p. 543) or (B) I believe that he has gone out. But he has not (1944, p. 204) would be “absurd” (1942, p. 543; 1944, p. 204). Wittgenstein’s letters to Moore show that he was intensely interested in this discovery of a class of possibly true yet absurd assertions. Wittgenstein thought that the absurdity is important because it is “something similar to a contradiction, thought (...) it isn’t one” (1974, p. 177). What is the explanation of the absurdity of saying or believing something about myself that might be true? Wittgenstein thought that although the explanation will say “something about the logic of assertion” it will also show that “logic isn’t as simple as logicians think it is”. So although the explanation should.. (shrink)

Mitchell's formulation of the chemiosmotic theory of oxidative phosphorylation in 1961 lacked any experimental support for its three central postulates. The path by which Mitchell reached this theory is explored. A major factor was the role of Mitchell's philosophical system conceived in his student days at Cambridge. This system appears to have become a tacit influence on his work in the sense that Polanyi understood all knowledge to be generated by an interaction between tacit and explicit knowing. Early in his (...) life Mitchell had evolved a simple philosophy based on fluctoids, fluctids and statids which was developed in a thesis submitted for the Ph.D. at the University of Cambridge, England. This aspect of his work was rejected by the examiners and became a tacit element in his intellectual development. It is argued from his various publications that this philosophy can be traced as an underlying theme behind much of Mitchell's theoretical writing in the 50's leading, through his notion of vectorial metabolism, to the formulation and amplification of the chemiosmotic theory in the sixties. This philosophy formed the basis for Mitchell of his understanding of biological systems and gave him his unique approach to cell biology. (shrink)

While Saint Augustine has been a household name for centuries, the same cannot be said of long-overlooked philosopher John Poinsot. But in _Augustine and Poinsot_, John Deely contends that the history of semiotics cannot be conceived of without Poinsot’s landmark contribution. According to Deely, even though Augustine was the first to describe _what_ the sign does, Poinsot was the first to show _how_ the sign mediates between nature and culture. This revolutionary volume demonstrates how Poinsot’s account of semiotics (...) allows us to produce human knowledge and experience. (shrink)

G. E. Moore famously observed that to say, “ I went to the pictures last Tuesday but I don’t believe that I did” would be “absurd”. Why should it be absurd of me to say something about myself that might be true of me? Moore suggested an answer to this, but as I will show, one that fails. Wittgenstein was greatly impressed by Moore’s discovery of a class of absurd but possibly true assertions because he saw that it illuminates “the (...) logic of assertion”. Wittgenstein suggests a promising relation of assertion to belief in terms of the idea that one “expresses belief” that is consistent with the spirit of Moore’s failed attempt to explain the absurdity. Wittgenstein also observes that “under unusual circumstances”, the sentence, “It’s raining but I don’t believe it” could be given “a clear sense”. Why does the absurdity disappear from speech in such cases? Wittgenstein further suggests that analogous absurdity may be found in terms of desire, rather than belief. In what follows I develop an account of Moorean absurdity that, with the exception of Wittgenstein’s last suggestion, is broadly consistent with both Moore’s approach and Wittgenstein’s. (shrink)

It is raining but you don’t believe that it is raining. Imagine accepting this claim. Then you are committed to saying ‘It is raining but I don’t believe that it is raining’. This would be an ‘absurd’ thing to claim or assert, yet what you say might be true. It might be raining, while at the same time, you are completely ignorant of the state of the weather. But how can it be absurd of you to assert something about yourself (...) that might be true of you? This is Moore’s paradox as it occurs in speech. What is the source of the absurdity? And why does it strike us that a contradiction is somehow at work when there is no contradiction in the content of what is asserted? In Section 2, I describe Moore’s formulation of the paradox and evaluate his own solutions. In Section 3, I discuss Wittgenstein’s inf luence in solving the paradox. In Section 4, I discuss Shoemaker’s priority thesis that once the absurdity in belief has been explained, then this will translate into an explanation of the absurdity in assertion. In Section 5, I discuss work on omissive and commissive Moore-paradoxical assertions, i.e. those of the forms p & I don’t believe that p and p & I believe that not-p. In Section 6, I discuss work on assertions of the form p & I don’t know that p. (shrink)

"In 1982, the author of this book issued a "promissory note" of just the sort that analytic philosophers of the twentieth century have led us to expect will come to nothing. This particular "note" occurred as a passing remark in the concluding chapter of his Introducing Semiotic (Indiana University Press) to the effect that it would be possible to establish the classical distinction between sense and intellect by means of the analysis of the role of relations in the action of (...) signs." "Provoked by the remark of a colleague that, could this promissory note be fulfilled, it would provide "the first essay worth reading on the subject since the days of Locke and Hume," Deely decided to break with the analytic tradition of leaving promissory notes unfulfilled and to develop the alleged possible proof in full." "A colloquium convened by Professor Norma Tasca, in the Fall of 1995 in Porto, Portugal, provided Deely with the occasion. His lengthy essay for the occasion, ponderously titled "The Intersemiosis of Perception and Understanding," became the initial draft of this book." "Especially in the circles of English-speaking philosophers, where a mere difference of degree between animal intelligence and human understanding has come to be largely taken for granted and philosophy has been reduced to a play of linguistic signs without regard for the dependency of those signs upon other signs whose play is far from linguistic, the work is bound to stimulate considerable debate."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

In (2004) I gave an argument for Evans’s principle -/- Whatever justifies me in believing that p also justifies me in believing that I believe that p -/- Hamid Vahid (2005) raises two objections against this argument. I show that the first is harmless and that the second is a non sequitur.

Clearly, if a man holds a self-contradictory belief, then his belief cannot be rational, for there can be no set of evidence sufficient to justify it. This is most apparent when the self contradictory belief is a belief in a conjunction, , rather than when it is a non-conjunctive self-contradictory belief, e.g. a belief that red is not a color.

The background to this paper is the question of how rational belief is possible in the light of the commonly presented infinite regress in reasons. The paper investigates the neglected question of whether this regress is vicious. I argue that given the genuine requirements of rational belief, The regress would require the rational believer to hold an infinity of beliefs, Which is impossible. The regress would not entail the rational believer holding an infinitely complex belief, Which, Admittedly, Would be logically (...) impossible. (shrink)

I argue that Moore's propositions, for example, 'I went to the pictures last Tuesday but I don't believe that I did' cannot be rationally believed. Their assertors either cannot be rationally believed or cannot be believed to be rational. This analysis is extended to Moorean propositions such as God knows that I am an atheist and I believe that this proposition is false. I then defend the following definition of assertion: anyone asserts that p iff that person expresses a belief (...) that p with the intention of causing relevant epistemic change in the cognition of an actual or potential audience.

Moore’s paradox is the fact that assertions or beliefs such asBangkok is the capital of Thailand but I do not believe that Bangkok is the capital of Thailand or Bangkok is the capital of Thailand but I believe that Bangkok is not the capital of Thailand are ‘absurd’ yet possibly true. The current orthodoxy is that an explanation of the absurdity should first start with belief, on the assumption that once the absurdity in belief has been explained then this will (...) translate into an explanation of the absurdity in assertion. This assumption gives explanatory priority to belief over assertion. I show that the translation involved is much trickier than might at first appear. It is simplistic to think that Moorean absurdity in assertion is always a subsidiary product of the absurdity in belief, even when the absurdity is conceived as irrationality. Instead we should aim for explanations of Moorean absurdity in assertion and in belief that are independent even if related, while bearing in mind that some forms of irrationality may be forms of absurdity even if not conversely.

There is an almost overwhelming mass of material available to the scholar who wishes to investigate the history of the text of Terence's plays. The manuscripts themselves number over 450 and of these over 100 belong to the period 800-c. 1300. No one, however, has undertaken a comprehensive recension of even the older group of medieval manuscripts. One reason for this is that the extent to which contamination has occurred makes classification extremely difficult, another is that it is unlikely that (...) the laborious task of examining and studying so many manuscripts will produce much new evidence for the text itself. Many of the corruptions which survive in the plays probably arose at an early stage in the tradition and prior to the archetype of the manuscripts which have been used by past editors. Any marked advance in the constitution of the text would seem to depend on the discovery of a manuscript which belonged to a different tradition. (shrink)

Inconsistency and contradiction are important concepts. Unfortunately, they are easily confused. A proposition or belief which is inconsistent is one which is self- contradictory and vice-versa. Moreover two propositions or beliefs which are contradictories are inconsistent with each other. Nonetheless it is a mistake to suppose that inconsistency is the same as contradiction.

This book shows otherwise. John Martin rehabilitates Neoplatonism, founded by Plotinus and brought into Christianity by St. Augustine.

Placebo-trials on HIV-infected pregnant women in developing countries like Thailand and Uganda have provoked recent controversy. Such experiments aim to find a treatment that will cut the rate of vertical transmission more efficiently than existing treatments like zidovudine. This scenario is first stated as generally as possible, before three ethical principles found in the Belmont Report, itself a sharpening of the Helsinki Declaration, are stated. These three principles are the Principle of Utility, the Principle of Autonomy and the Principle of (...) Justice. These are taken as voices of moral imperative. But although each has intuitive appeal, it can be shown that there are possible scenarios in which they give conflicting prescriptions. To achieve consistency, one must be subordinate to the others. The voice of utility is taken as subordinate to those of justice and autonomy and it is shown that given plausible assumptions about the level of poverty and education in the developing country targeted, the experiment is ruled morally wrong in the name of both justice and autonomy. Moreover, it is argued that no justification can be found for the inclusion of a placebo group, when strictly defined. By contrast, a ‘no- treatment’ control arm might be justified, but only when the demands of autonomy are satisfied, demands that are more stringent than they might appear. A utilitarian defence of the experiment is examined, namely that the would-be participants are in a no-loss situation, and it is shown that this defence is seriously flawed. Finally, it is concluded that there is no justification for amending the Declaration of Helsinki. (shrink)

Contrary to what the author dismisses as false claims of postmodernity, the work shows that what is truly postmodern in philosophy both goes beyond modernity and recovers philosophy's past in a renewed understanding of the human condition.

In 2004, I explained the absurdity of Moore-paradoxical belief via the syllogism (Williams 2004): (1) All circumstances that justify me in believing that p are circumstances that tend to make me believe that p. (2) All circumstances that tend to make me believe that p are circumstances that justify me in believing that I believe that p. (3) All circumstances that justify me in believing that p are circumstances that justify me in believing that I believe that p. I then (...) took (3) to mean (EP) Whatever justifies me in believing that p justifies me in believing that I believe that p.1 Now suppose that I am justified in believing anything of the omissive Mooreparadoxical form: (Om) p and I do not believe that p. Then I am justified in believing the first conjunct. So by (EP) I am justified in believing that I believe that p. But since I am also justified in believing the second conjunct, I am justified in believing that I do not believe that p. I claimed that this is impossible, because anything that justifies me in believing that something is the case renders me unjustified in believing that it is not the case. This syllogism is plausible from an externalist view of justification, according to which circumstances such as seeming to see rain under normal perceptual conditions, justify me in believing that it is raining. In support of (1), if my apparent perceptions of rain are reliably connected with rain, so as to justify me in thinking that it is raining, they also tend to make me believe that it is raining. In support of (2), my apparent perceptions of rain are also reliably connected with my coming to believe that it is raining. However, Anthony Brueckner (2006) argues that (1) and (EP) are both false once justification is thought of evidentially. Against (EP), he claims that my evidence that p is not evidence that I believe that p unless I possess the evidence, in the sense that I believe it and were I to believe that p on its basis.

‘Feuerbach resolves the religious essence into the human essence. But the human essence is no abstraction inherent in each single individual. In its reality it is the ensemble of social relations.’It is a common belief, shared both by Marxists and by critics of Marxism, that differences in the interpretation of this statement have important implications for the assessment of Marx's system of ideas. How we read it will affect our view of the unity of Marx's thought and of the continuity (...) of its development over his lifetime, and it will bear crucially on our appraisal of the epistemological status—metaphysical, scientific or mythopoeic—of the various elements of the Marxian system. Among Marxists, members of the Frankfurt School have emphasized the paternity of Marxian metaphysical humanism in Hegel's conception of man as a self-creating being, while Althusser and his disciples have seen in the extrusion from Marx's later work of any such ‘anthropomorphic’ notion a guarantee of the scientific character of his historical materialism. Among Marx's liberal critics, it is widely agreed that he espoused an essentialist view of man and, often enough, it is thought that this alone is sufficient to disqualify his system from scientific status. No consensus exists, however, as to the cognitive standing of the several components of Marx's thought. That agreement should be lacking as to the place in it of a conception of human nature is hardly surprising. Different construals of the role of a view of man will reflect divergent commitments, not only in the philosophy and methodology of social and historical inquiry, but in moral and political thought as well.

Eventually and inevitably the study of a Roman comedy leads to the question of its relationship to the Greek model and to the nature of the original play. In recent years Terence's Adelphoe has stimulated numerous publications on the Menandrian comedy and on the changes which were made by the Latin dramatist. Greatest attention has been paid to the ending of the Greek play. This article, however, will examine the first two ‘acts’ of the Terentian comedy and will offer a (...) reconstruction of its primary model that differs from those that have been proposed in the major studies on this problem.

It is widely accepted that scientific theories should be simple, have inductive support and high empirical content, while other theories should be accurate and have high explanatory power. This book argues that these features can all be reduced to a single feature - the independence of theory from data. It also argues that theories possessing this feature are more likely to be true than those that don't.

This essay focuses on the development of Latin semiotics from Ockham to Poinsot as it took place mainly in the Iberian university world, with a discussion of the consequences of that development for logic and philosophy today.

Virtue epistemology is new in one sense but old in another. The new tradition starts with figures such as Code, Greco, Montmarquet, and Zagzebski. The old tradition has its pedigree in Plato, Aristotle, Aquinas, and their modern interpreters such as Anscombe and MacIntyre. Virtue epistemology recognizes that knowledge is something we value and that propositional knowledge requires intellectual virtues, that is to say, virtues as applied to the intellect. Although much pioneering work in the new tradition has been done on (...) propositional knowledge, comparatively little in it has been done on know-how. This is surprising, because one might naturally think of know-how as something to be refined into a skill, and virtues may be thought of as skills. In the modern epistemological tradition that does not take its direction from virtue ethics, propositional knowledge, as opposed to know-how, has received by far the bulk of the discussion, although since Ryle first argued that knowhow is not always propositional knowledge, there has been a fairly recent resurgence of interest in know-how.We value intellectual virtues because they are skills that promote our flourishing, both as individuals and as members of a community. The intellectual virtues are truth- seeking virtues and stem from a love of the truth. Since love is itself a virtue - indeed it was what Tyndale called the greatest Christian virtue before the King James translation renamed it as charity—it may be seen as the virtue that motivates all other intellectual virtues. A commitment to the truth is presupposed by any intellectual virtue. For example, logic is important to a community, and in particular to the intellectual community, not only because there are rules governing the activity of logic but also because there are those within the community who are trustworthy in following the activity and because there are publically accepted standards of accountability in the way the activity of logic is practiced. Here is how we will proceed. In section 2 we sketch a metaphysics of natural purposes that supports the claim that there are objective goods that beings need qua the kinds of being they are in order to flourish. In section 3 we argue that flourishing includes the acquisition of virtues. We give a general account of virtue, roughly as a stable disposition to act upon a habit elevated to a skill of putting one’s know-how into practice that springs from one’s motivation to pursue what one perceives as good. In section 4 we give a general sketch of intellectual virtues as truth-seeking virtues that stem from a love of the truth that are the skills to flourish intellectually. In section 5 we discuss connaturality, namely those specific metaphysical accidents readily acquired by beings due to their first nature. We make an original distinction between ontological connaturality, namely the connaturality that belongs to animals qua beings of a certain kind, and habitual connaturality, namely our first natures suffused with virtues—or vices, although we will concentrate only on virtues. Habitual connaturality is acquired through the practice of virtue and involves perceptiveness awakened by the possession of the virtue in question. The knowledge arising from this form of connaturality may be a form of know-how. In section 6 we give an account of connatural apprehension and connatural propositional knowledge. In section 7 we discuss connatural know-how and argue that it makes certain virtues possible. At this point we will have shown that intellectual and moral virtues are informed by know-how. In sections 8 and 9 we give analyses of know-how and skill in terms of counterfactual success. We show how skill is a refined form of know-how and how both know-how and skill are informed by moral and intellectual virtues. We conclude in section 10 that know-how informs intellectual and moral virtues in the sense that virtue is to be elucidated in terms of skill, which is in turn to be elucidated in terms of know-how. Moreover, virtues inform know-how in the sense that know-how is to be elucidated in terms of intellectual and moral virtues. No circularity arises because different virtues and different forms of know-how are involved. (shrink)

The mediaeval logic of Aristotelian privation, represented by Ockham's expositionof All A is non-P as All S is of a type T that is naturally P and no S is P, iscritically evaluated as an account of privative negation. It is argued that there aretwo senses of privative negation: (1) an intensifier (as in subhuman), the dualof Neoplatonic hypernegation (superhuman), which is studied in linguistics asan operator on scalar adjectives, and (2) a (often lexicalized) Boolean complementrelative to the extension of (...) a privative negation in sense (1) (e.g., Brute). Thissecond sense, which is the privative negation discussed in modern linguistics, isshown to be Aristotle's. It is argued that Ockham's exposition fails to capture muchof the logic of Aristotelian privation due to limitations in the expressive power of thesyllogistic. (shrink)

This paper is roughly in two parts. The first deals with whether know-how is constituted by propositional knowledge, as discussed primarily by Gilbert Ryle (1949) The concept of mind. London: Hutchinson, Jason Stanley and Timothy Williamson (2001). Knowing how. Journal of Philosophy, 98, pp. 411–444 as well as Stephen Hetherington (2006). How to know that knowledge-that is knowledge-how. In S. Hetherington (Ed.) Epistemology futures. Oxford: Oxford University Press. The conclusion of this first part is that know-how sometimes does and sometimes (...) does not consist in propositional knowledge. The second part defends an analysis of know-how inspired by Katherine Hawley’ (2003). Success and knowledge-how. American Philosophical Quarterly, 40, pp. 19–31, insightful proposal that know-how requires counterfactual success. I conclude by showing how this analysis helps to explain why know-how sometimes does and sometimes does not consist of propositional knowledge. (shrink)
