By a `denoting phrase' I mean a phrase such as any one of the following: a man, some man, any man, every man, all men, the present King of England, the present King of France, the center of mass of the solar system at the first instant of the twentieth century, the revolution of the earth round the sun, the revolution of the sun round the earth. Thus a phrase is denoting solely in virtue of its form. We may distinguish (...) three cases: (1) A phrase may be denoting, and yet not denote anything; e.g., `the present King of France'. (2) A phrase may denote one definite object; e.g., `the present King of England' denotes a certain man. (3) A phrase may denote ambiguously; e.g. `a man' denotes not many men, but an ambiguous man. The interpretation of such phrases is a matter of considerably difficulty; indeed, it is very hard to frame any theory not susceptible of formal refutation. All the difficulties with which I am acquainted are met, so far as I can discover, by the theory which I am about to explain. (shrink)

The absurdity of (i) and (ii) arises because asserting 'p' normally expresses a belief that p. Normally, when (i) is asserted, what is conjointly expressed and asserted, i.e. a belief that p and a lack of belief that p, is logically impossible, whereas normally, when (ii) is asserted, it is differently absurd, since what is conjointly expressed and asserted, i.e. a belief that p and a belief that -p, is logically possible, but inconsistent. A possible source of confusion between 'impossible' (...) and 'inconsistent' is the fact that a proposition which is inconsistent tout court is always self-contradictory and hence necessarily false, unlike one which is inconsistent with other propositions. Whereas the proposition Ibp&-Ibp is inconsistent, the proposition IBp &IB-p is not. I cannot hold a belief which I lack, but I can.. (shrink)

Wittgenstein finished part 1 of the Philosophical Investigations in the spring of 1945. From 1946 to 1949 he worked on the philosophy of psychology almost without interruption. The present two-volume work comprises many of his writings over this period. Some of the remarks contained here were culled for part 2 of the Investigations ; others were set aside and appear in the collection known as Zettel . The great majority, however, although of excellent quality, have hitherto remained unpublished. This bilingual (...) edition of the Remarks on the Philosophy of Psychology presents the first English translation of an essential body of Wittegenstein's work. It elaborates Wittgenstein's views on psychological concepts such as expectation, sensation, knowing how to follow a rule, and knowledge of the sensations of other persons. It also shows strong emphasis on the "anthropological" aspect of Wittgenstein's thought. Philosophers, as well as anthropologists, psychologists, and sociologists will welcome this important publication. (shrink)

Response to Don Baxter, Don Garrett and Jennifer Marusic regarding my book Imagined Causes: Hume's Conception of Objects; initially delivered at the 2016 Hume Conference in Sydney, Australia as part of the Author Meets Critics session.

This book is available either individually, or as part of the specially-priced Arguments of the Philosphers Collection.

The preface paradox strikes us as puzzling because we feel that if a person holds a set of inconsistent beliefs, i.e. beliefs such that at least one of them must be correct, then he should give at least one of them up. Equally, if a person's belief is rational, then he has a right to hold it. Yet the preface example is prima facie a case in which a person holds an inconsistent set of beliefs each of which is rational, (...) and thus a case in which that person has a duty to relinquish what he has a right to keep.

Discussions of what is sometimes called 'Moore's paradox' are often vitiated by a failure to notice that there are two paradoxes; not merely one in two sets of linguistic clothing. The two paradoxes are absurd, but in different ways, and accordingly require different explanations.

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.

Wittgenstein was one of the most powerful influences on contemporary philosophy, yet he shunned publicity and was essentially a private man. This remarkable, vivid, personal memoir is written by one of his friends, the eminent philosopher Norman Malcolm. Reissued in paperback, this edition includes the complete text of fifty-seven letters which Wittgenstein wrote to Malcolm over a period of eleven years. Also included is a concise biographical sketch by another of Wittgenstein's philosopher friends, Georg Henrik von Wright. 'A reader does (...) not need to care about philosophy to be excited by Mr Malcolm's book; it is about Wittgenstein as a man, and its interest is human interest'. (shrink)

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.

Sorensen here offers a unified solution to a large family of philosophical puzzles and paradoxes through a study of "blindspots": consistent propositions that cannot be rationally accepted by certain individuals even though they might by true.

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)
