_Plato's Thought_ offers an excellent introduction to Plato, guiding the reader through Plato's Theory of Forms, and examining his views on art, education and statecraft. This edition includes an introduction, bibliographic essay, and bibliography by Donald Zeyl.

First published in 1962, this book provides a systematic account of the development of Plato’s theory of knowledge. Beginning with a consideration of the Socratic and other influences which determined the form in which the problem of knowledge first presented itself to Plato, the author then works through the dialogues from the Meno to the Laws and examines in detail Plato’s progressive attempts to solve the problem.

This book provides an introduction to Plato’s work that gives a clear statement of what Plato has to say about the problems of thought and life. In particular, it tells the reader just what Plato says, and makes no attempt to force a system on the Platonic text or to trim Plato’s works to suit contemporary philosophical tastes. The author also gives an account that has historical fidelity - we cannot really understand the Republic or the Gorgias if we forget (...) that the Athens of the conversations is meant to be the Athens of Nicias or Cleon, not the very different Athens of Plato’s own manhood. To understand Plato’s thought we must see it in the right historical perspective. (shrink)

Origins of language. It is asserted that the work reveals an issue crucial to his philosophy, namely his ambiguous response to language. Plato's most basic assertion is that words are mere imitations of reality and cannot be trusted to be an accurate mode of transmitting knowledge. Plato refuses to take a systematic position towards language by mingling the divine with the human and the conventional with the natural. The easily proven ambiguity of plato's theory of language is shown to be (...) the basis of many of the problems in his metaphysics, epistemology, and aesthetics. (shrink)

It is now nearly axiomatic among Platonic scholars that the Timaeus and its unfinished sequel the Critias belong to the last stage of Plato's writings. The Laws is generally held to be wholly or partly a later production. So, by many, is the Philebus, but that is all. Perhaps the privileged status of the Timaeus in the Middle Ages helped to fix the conviction that it embodies Plato's maturest theories.

Truth of x (independently of any description of x) that it is f. A property f which holds of x but is not per se of x is said to hold per accidens of x. The essence of an individual is the sum of its per se properties. We can formulate the following: doctrine a: concrete individuals do not have essences though abstract entities do. Doctrine b: concrete individuals have essences but they do not individuate, whereas abstract entities have essences (...) which do individuate. Assumption i: we shall say that a thing exists insofar as it has an essence. Assumption ii: we shall say that we know a thing when we know what its per se properties are. We argue that plato held doctrine a and aristotle doctrine b (with assumptions i and ii). (edited). (shrink)

All volumes of Professor Guthrie's great history of Greek philosophy have won their due acclaim. The most striking merits of Guthrie's work are his mastery of a tremendous range of ancient literature and modern scholarship, his fairness and balance of judgement and the lucidity and precision of his English prose. He has achieved clarity and comprehensiveness.

Towards the close of Book V of theRepublicPlato tells us that the true philosopher has knowledge and that the objects of knowledge are the Forms. By contrast, the ‘lovers of sights and sounds’, he tells us, have no more than belief, the objects of which are physical particulars. He then goes on to present us with some very radical-sounding assertions about the nature of these physical particulars. They are bearers of opposite properties, he says, in so thorough-going a manner that (...) we cannot say of them that they are nor that they are not: they lie somewhere between being and utter non-being.This passage of theRepublic still awaits an agreed interpretation and I want to suggest as a reason for this that it is usually interpreted in isolation. I will argue that it becomes easier to understand when seen against the background of Plato's developing thought. To be more precise, it makes sense when taken as a rejection by Plato of one of his earlier beliefs: namely, a doctrine of essentialism to be found in thePhaedo.The greater part of this paper then will be an attempt to show thatRepublicV is a rejection of thePhaedo'sdoctrine of essences. Its concluding part will try to explain why that doctrine was rejected. (shrink)

First published in 1974, J.N. Findlay's classic work on Plato has now been re-issued.

Yet, that the Cratylus is of philosophical significance seems to me to be an assumption we can safely make. Plato rarely discusses other than philosophical problems--and even these other discussions are raised and carried on in the context of philosophical questions. Moreover, he could hardly be expected to write a whole dialogue of no philosophical concern and significance. To understand what the philosophical significance of the Cratylus is in general, and for Plato's thought in particular, we must be clear about (...) the question Plato is trying to answer and the answer he gives to this question. That is, we must be clear about the question of the Cratylus: What is the correctness of names? and the two answers to the question Plato considers: convention, and natural correctness. (shrink)

This is, as from the author of The Concept of Mind it could scarcely fail to be, a bold and rollicking book. It is also one of the most important works about Plato to have appeared since the first volume of Sir Karl Popper's The Open Society. Whereas The Concept of Mind was a general offensive against Cartesian views of man, eschewing any precise references to particular sources, Plato's Progress deals with scholarly questions of datings and developments, showing and demanding (...) familiarity with a wide literature. Yet Professor Ryle is still incapable as ever of the dry-as-dust. (shrink)

In this paper I want to do the following things. First I want to show that in the part of the Theaetetus where the relationship between knowledge and perception is examined, the concept of knowledge that is in question is very clearly characterized. We are left in no doubt as to what is to count as knowing. Secondly I want to unravel in some detail the case that Socrates puts on Protagoras’ behalf where he draws on what Protagoras actually wrote (...) (151 E-152C); as opposed to what he may have taught secretly to his pupils (152C-160D). Thirdly I wish to argue that if we let the dialogue speak for itself, it is manifest that this case put up on Protagoras’ behalf at 151 E-152C is not overthrown; it is not even shaken. (shrink)
