David Bostock examines the theories and arguments put forward by Plato in his Phaedo, in which he attempts to show that the soul is immortal. This excellent introduction to Plato's often difficult arguments discusses such important philosophical problems as the nature of the mind, the idea of personal identity, the question of how we understand language, and the concept of cause, reason, and explanation.

The Regress: Knowledge, we like to suppose, is essentially a rational thing: if I claim to know something, I must be prepared to back up my claim by statingmy reasons for making it;and if my claim is to be upheld, my reasons must begood reasons. Now suppose I know that Q; and let my reasons be conjunctively contained in the proposition that R. Clearly, I must believe that R ;equally clearly, I must know that R . Thus if I know (...) that Q, I know that R. But if I know that R, then I must have my reasons, R' for holding R; and, by the same argument, I mustknow that R'. And if R', then R”; and so on, ad infinitum. (shrink)

I discuss in this paper the six requirements Aristotle advances at Posterior Analytics A-2, 71b20-33, for the premisses of a scientific demonstration. I argue that the six requirements give no support for an intepretation in terms of “axiomatization”. Quite on the contrary, the six requirements can be consistently understood in a very different picture, according to which the most basic feature of a scientific demonstration is to explain a given proposition by its appropriate cause.

I examine Aristotle’s definition of scientific knowledge in Posterior Analytics 71b 9-12 and try to understand how it relates to the sophistical way of knowing and to "kata sumbebekos knowledge". I claim that scientific knowledge of p requires knowing p by its appropriate cause, and that this appropriate cause is a universal (katholou) in the restricted sense Aristotle proposes in 73b 26-27 ff., i.e., an attribute coextensive with the subject (an extensional feature) and predicated of the subject in itself (an (...) intensional feature). Kata sumbebekos knowledge, on the other hand, can occur even when the predicate of a conclusion is coextensive with its subject and is proved by a convertible meson which is not the most appropriate from an explanatory standpoint.

Terence Irwin presents a historical and critical study of the development of moral philosophy over two thousand years, from ancient Greece to the Reformation. Starting with the seminal ideas of Socrates, Plato, and Aristotle, he guides the reader through the centuries that follow, introducing each of the thinkers he discusses with generous quotations from their works. He offers not only careful interpretation but critical evaluation of what they have to offer philosophically. This is the first of three volumes which will (...) examine the history of ethics in the Socratic tradition, up to the late 20th century. (shrink)

Debates about scientific realism are closely connected to almost everything else in the philosophy of science, for they concern the very nature of scientific knowledge. Scientific realism is a positive epistemic attitude toward the content of our best theories and models, recommending belief in both observable and unobservable aspects of the world described by the sciences. This epistemic attitude has important metaphysical and semantic dimensions, and these various commitments are contested by a number of rival epistemologies of science, known collectively (...) as forms of scientific antirealism. This article explains what scientific realism is, outlines its main variants, considers the most common arguments for and against the position, and contrasts it with its most important antirealist counterparts.

This is a welcome reprint of a book that continues to grow in importance.

Aristotle's Nicomachean Ethics, which equates the ultimate end of human life with happiness, is thought by many readers to argue that this highest goal consists in the largest possible aggregate of intrinsic goods. Richard Kraut proposes instead that Aristotle identifies happiness with only one type of good: excellent activity of the rational soul. In defense of this reading, Kraut discusses Aristotle's attempt to organize all human goods into a single structure, so that each subordinate end is desirable for the sake (...) of some higher goal. This book also emphasizes the philosopher's hierarchy of natural kinds, in which every type of creature achieves its good by imitating divine life. As Kraut argues, Aristotle's belief that thinking is the sole activity of the gods leads him to an intellectualist conception of the ethical virtues. Aristotle values these traits because, by subordinating emotion to reason, they enhance our ability to lead a life devoted to philosophy or politics. (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.

A study of the relationship between the Eudemian and Nichomachean Ethics of Aristotle.

Parmenides is generally recognized as Plato's most difficult dialogue. This work argues that the key to unlocking the puzzles of Parmenides II lies in the proper interpretive pairing of the eight hypotheses under which its arguments are grouped.

Putnam discusses each of the fifteen odes found in the book, studying the work both as a whole and as a series of interactive units.

Plato is a much more experimental philosopher, this book argues, than most commentators acknowledge. Supporting this position, Henry Teloh combines exegesis of particular passages with a synoptic view of Plato's philosophical development through his early, middle, and late dialogues. The result is a study of Plato's ideas with a more ambitious scope than any since W. D. Ross's in 1951,The book chronicles Plato's changing interests through a focus on his ontological commitments—that is, on the types of entities he addresses. It (...) also traces many of the assumptions in Plato's thought back to their sources in pre-Socratic philosophy. By depicting the changes in Plato's thought from one period of dialogue composition to another, and by seeking to explain these changes from textual evidence, this book offers an appealing introduction to Plato for all humanists.

Published in 1987: The following essays form, as their title-page shows, only the first half of a collection which the writer hopes to complete in the course of a few months. Even when completed the whole work is designed to be merely preparatory to another on the interpretation of the Platonic Philosophy, and the materials brought together in the following pages, as well as those which, it is trusted, will form their continuation, were originally intended to appear in the Introduction (...) to that projected work.

The Dialectic of Essence offers a systematic new account of Plato's metaphysics. Allan Silverman argues that the best way to make sense of the metaphysics as a whole is to examine carefully what Plato says about ousia (essence) from the Meno through the middle period dialogues, the Phaedo and the Republic, and into several late dialogues including the Parmenides, the Sophist, the Philebus, and the Timaeus. This book focuses on three fundamental facets of the metaphysics: the theory of Forms; the (...) nature of particulars; and Plato's understanding of the nature of metaphysical inquiry. Silverman seeks to show how Plato conceives of "Being" as a unique way in which an essence is related to a Form. Conversely, partaking ("having") is the way in which a material particular is related to its properties: Particulars, thus, in an important sense lack essence. Additionally, the author closely analyzes Plato's idea that the relation between Forms and particulars is mediated by form-copies. Even when some late dialogues provide a richer account of particulars, Silverman maintains that particulars are still denied essence. Indeed, with the Timaeus's introduction of the receptacle, there are no particulars of the traditional variety. This book cogently demonstrates that when we understand that Plato's concern with essence lies at the root of his metaphysics, we are better equipped to find our way through the labyrinth of his dialogues and to better appreciate how they form a coherent theory.

In lieu of an abstract, here is a brief excerpt of the content:Notes and Discussions HEDONISM IN THE PROTAGORAS SOME INSOLUBLEPROBLEMSOf historical scholarship are posed by the fact that the hero of Plato's dialogues was also an historical figure. Commentators are prone to identify the Socrates of the dialogues with the man who drank the hemlock and walked the streets of Athens. This is perhaps unexceptionable 9 But beyond this they are often tempted (even when they know better) to speak (...) of the dialogues as if they were reports or descriptions of actual events in the life of the historical Socrates. Even so astute a scholar as Gregory Vlastos, in his recent lucid Introduction to the Protagoras, falls into this pit. The dramatic date of the Protagoras is no later than 433, five years before the birth of Plato. It would require clear and strong evidence (of which there is none) to convince us that a verbatim report of this encounter was preserved for thirty years or more, to be handed on to Plato at the appropriate moment. Vlastos, of course, would laugh at this suggestion, but hear him talking about the logic of Socrates' argument: I trust I have made it clear that Socrates' performance in this argument is much better than would appear from the fact, which it would be folly to hush up, that he has made a definite error. For the error he does make is one that he could easily have detected when he got the chance to think out his moves in a more leisurely moment. He would then have seen that he could have produced a valid deductive argument for his immediate objective, and did not have to revoke a single inference he had made.... This is not to deny that he occasionally makes grave errors. 9 It is only to insist that as a practitioner of logical inference, and one who practices on his feet, in the stress of live debate, and with no calculus or any formal patterns of valid inference to guide him, Socrates is not a bungler, but a master? This is all very well, except that the argument Vlastos is discussing was not constructed in the stress of live debate but rather, as it were, in the cool of Plato's study. Plato was not practicing on his feet, and, we may presume, had ample time to think through and revise the arguments in question. Are we to interpret Vlastos as claiming that in later, real encounters witnessed by Plato, Socrates did argue in this way? And that Plato here has Socrates commit logical errors (which he, Plato, knows are errors; for he has Protagoras object to them) in order to portray Socrates as a man who makes frequent mistakes but thinks pretty well on his feet? 1Plato's Protagoras, edited, with an Introduction, by Gregory Vlastos (New York, Liberal Arts Press, 1956), pp. xxxv-xxxvi. [7s] 74 HISTORY OF PHILOSOPHY In fact, we tend to think of the dialogues as having two authors, Plato and Socrates, and we frequently cannot choose between them. In the Protagoras it is even worse; for many scholars have assumed the existence of a third author, Protagoras, who is credited with having written at least part of his role in the dialogue. I offer here the radical thesis that the Protagoras has but one author, Plato, and that everything in the dialogue is to be laid to him.2 My assumptions are that from beginning to end the Protagoras is a product of Plato's imagination, and that Plato is primarily a philosopher and only secondarily a biographer--or perhaps we might say he is a biographer of ideas, not of persons. The philosophical stances assumed by the disputants may or may not resemble those of the historical figures, but we have no reason to attribute the words spoken or the turns taken in the argument to anyone but Plato. The question, why does Socrates say this at this point, must, if it is to be sensible, mean why does Plato have Socrates say this at this point. The answers, if there are answers, will be found within the dialogues and not in speculative history. In the final argument in the Protagoras (351b... (shrink)

Aristotle's philosophically most explicit and sophisticated account of the concept of a (primary-)universal proof is found, not in "Analytica Posteriora" 1.4, where he introduces the notion, but in 1.5. In 1.4 Aristotle merely says that a universal proof must be of something arbitrary as well as of something primary and seems to explain primacy in extensional terms, as concerning the largest possible domain. In 1.5 Aristotle improves upon this account after considering three ways in which we may delude ourselves into (...) thinking we have a primary-universal proof. These three sources of delusion are shown to concern situations in which our arguments do establish the desired conclusion for the largest possible domain, but still fail to be real primary-universal proofs. Presupposing the concept of what may be called an immediate proof, in which something is proved of an arbitrary individual, Aristotle in response now demands that a proof be immediate of the primary thing itself and goes on to sketch a framework in which an intensional criterion for primacy can be formulated. For the most part this article is a comprehensive and detailed commentary on Aristotle's very concise exposition in 1.5. One important result is that the famous passage 74a17-25 referring to two ways of proving the alternation of proportions cannot be used as evidence for the development of pre-Euclidean mathematics.
