Based on concepts of self-organization, we interpret apparent motion as the result of a so-called non-equilibrium phase transition of the perceptual system with the stimulus-onset asynchrony (SOA) acting as a control parameter. Accordingly, we predict a significantly increasing variance of the quality index of apparent motion close to critical SOAs. [Shepard].

The pages of the history of science record thousands of instances of similar discoveries having been made by scientists working independently of one another. Sometimes the discoveries are simultaneous or almost so; sometimes a scientist will make anew a discovery which, unknown to him, somebody else had made years before.

Quentin Smith contends that modern science provides enough evidence ‘to justify the belief that the universe began to exist without being caused to do so.’ There was a time when such a claim would have been dismissed because it conflicts with a principle absolutely fundamental to all human thought, including science itself. As Thomas Reid expressed the matter: That neither existence, nor any mode of existence, can begin without an efficient cause is a principle that appears very early in the (...) mind of man; and it is so universal, and so firmly rooted in human nature, that the most determined scepticism cannot eradicate it.

I compare the two main readings of the argument against Protagorean relativism that 'Socrates' presents at Theaetetus 170-171, argue against both of them, and present a third alternative reading.

Philosophical Studies Vol. 2, No. 2, p. 163, l. 24 for ‘Pocreon’ read “Creon’ and p. 165, l.4 for “Nereus” read “Nessus”, l. 16 for “Corrolate” read “Correlate” and l. 27 for “ Trachinae ” read “ Trachiniae ”. Proffessor Mackinnon should also have been described as Norris-Hulse Professor of Divinity in the University of Cambridge and Fellow of Corpus Christi College.

I propose to examine what I take to be the point at issue between subjectivist and objectivist theories of ethics and to explain that the controversy between them is unreal. It springs from a misunderstanding of the nature of appraisal sentences. What I hope to show is that if such sentences were really analysable in the way in which the critics and many of the supporters of subjectivist theories suppose, then those theories would indeed, as it is sometimes put “fail (...) to do justice to the facts of moral experience.” But it seems to me that objectivist theories are no better off. They make exactly the same mistake though in a more sophisticated way. I therefore propose to see whether any useful results can be achieved by construing appraisal sentences on rather different lines. By appraisal sentences I mean sentences of the form “I approve of …, I think well of …, I commend …, etc.” I shall call these simple appraisals, sentences of the form “… is good, … is meritorious, … is praiseworthy, etc.” I shall call these moral appraisals. In these terms, subjectivist theories assert that moral appraisals can always be expressed without change of meaning by simple appraisals, though perhaps the addition of an imperative sentence of some kind is required to complete the translation. Objectivist theories deny this possibility and claim that moral appraisals assert truths about the independent world and not psychological facts about the speaker. (shrink)
