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.

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.

Scholars ubiquitously refer to the method εξ υποθεσεως, introduced at Meno 86e1-87d8, as a method of hypothesis. In contrast, this paper argues that the method εξ υποθεσεως in Meno is not a hypothetical method. On the contrary, in the Meno passage, υποθεσις means “postulate”, that is, cognitively secure proposition. Furthermore, the method εξ υποθεσεως is derived from the method of geometrical analysis. More precisely, it is derived from the use of geometrical analysis to achieve reduction, that is, reduction of a (...) less tractable problem to a more tractable problem. As such, the method εξ υποθεσεως does not by itself serve to solve problems. (shrink)

This paper examines socrates' method for determining whether virtue is taught, And discusses some of the opposing interpretations that have been offered (e.G., By robinson and hackforth). Some major conclusions are: that hypotheses that have been deduced from other hypotheses can still be called hypotheses; that it is false that there can be only one hypothesis per argument; and that the several hypotheses in a given argument need not all be hypothesized with the same degree of confidence.

Late ancient Platonists and Aristotelians describe the method of reasoning to first principles as "analysis." This is a metaphor from geometrical practice. How far back were philosophers taking geometric analysis as a model for philosophy, and what work did they mean this model to do? After giving a logical description of analysis in geometry, and arguing that the standard (not entirely accurate) late ancient logical description of analysis was already familiar in the time of Plato and Aristotle, I argue that (...) Plato, in the second geometrical passage of the "Meno" (86e4-87b2), is taking analysis as a model for one kind of philosophical reasoning, and I explore the advantages and limits of this model for philosophical discovery, and in particular for how first principles can be discovered, without circularity, by argument.

This paper examines the second geometrical problem in the Meno. Its purpose is to explore the implication of Cook Wilson’s interpretation, which has been most widely accepted by scholars, in relation to the nature of hypothesis. I argue that (a) the geometrical hypothesis in question is a tentative answer to a more basic problem, which could not be solved by available methods at that time, and that (b) despite the temporary nature of a hypothesis, there is a rational process for (...) formulating it. The paper also contains discussion of the method of analysis, problem reduction and a diorism, which have often been ambiguously explained in relation to the geometrical problem in question.

In Meno 80d5-e5, we find two sets of objections concerning the possibility of inquiry in the absence of knowledge: the so-called Meno's paradox and the eristic arguments. This essay first shows that the eristic argument is not simply a restatement of Meno's paradox, but instead an objection of a completely different kind: Meno's paradox concerns not inquiry as such, but rather Socrates' inquiry into virtue as is pursued in the first part of the Meno, whereas the eristic argument indicates a (...) manner in which Meno's paradox can be generalized. This implies that they cannot be resolved by the same argument. It is then argued that the theory of recollection, as presented in Socrates' experiment with the slave, cannot resolve Meno's paradox, its target being only the eristic argument. Only the hypothetical method of inquiry is the effective answer to Meno's paradox. Finally, this essay contends that, contrary to what the text might suggest, Socrates, by introducing the hypothetical method, does not abandon his principle that knowing what something is precedes knowing what something is like.

I argue that the technique Socrates describes in the Meno at 86e-87c allows him to make progress without definitions, even while accepting that definitions are necessary for knowledge. Some contend that the technique involves provisionally accepting a claim. I argue, instead, that it provides a secure biconditional that one can use to reduce the question one cares care about to a new question that one thinks will be easier to answer.

One of very few monographs devoted to Plato's Meno, this study emphasizes the interplay between its protagonists, Socrates and Meno. It interprets the Meno as Socrates' attempt to persuade his interlocutor, by every device at his disposal, of the value of moral inquiry—even though it fails to yield full-blown knowledge—and to encourage him to engage in such inquiry, insofar as it alone makes human life worth living.

Given its brevity, Plato's Meno covers an astonishingly wide array of topics: politics, education, virtue, definition, philosophical method, mathematics, the nature and acquisition of knowledge and immortality. Its treatment of these, though profound, is tantalisingly short, leaving the reader with many unresolved questions. This book confronts the dialogue's many enigmas and attempts to solve them in a way that is both lucid and sympathetic to Plato's philosophy. Reading the dialogue as a whole, it explains how different arguments are related to (...) one another and how the interplay between characters is connected to the philosophical content of the work. In a new departure, this book's exploration focuses primarily on the content and coherence of the dialogue in its own right and not merely in the context of other dialogues, making it required reading for all students of Plato, be they from the world of classics or philosophy.
