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.

Two masterpieces of Plato's later period. The Theaetetus offers a systematic treatment of the question "What is knowledge?" The Sophist follows Socrates' cross-examination of a self-proclaimed true philosopher.

Nicholas D. Smith presents an original interpretation of the Republic, considering it to be a book about knowledge and education. Over the course of Summoning Knowledge in Plato's Republic, he argues for four main theses. Firstly, the Republic is not just a work that has a lot to say about education; it is a book that depicts Socrates as attempting to engage his interlocutors in such a way as to help to educate them and also engages us, the readers, in a way that helps to educate us. Secondly, Plato does not suppose that education, properly understood, should have as its primary aim putting knowledge into souls that do not already have it. Instead, the education Plato discusses, represents occurring between Socrates and his interlocutors, and hopes to achieve in his readers is one that aims to arouse the power of knowledge in us and then to begin to train that power always to engage with what is more real, rather than what is less real. Thirdly, Plato's conception of knowledge is not the one typically presented in contemporary epistemology. It is, rather, the power of conceptualization by the use of exemplars. And finally, Plato engages this power of knowledge in the Republic in a way he represents as only a kind of second-best way to engage knowledge - and not as the best way, which would be dialectic. Instead, Plato uses images that summon the power of knowledge to begin the process by which the power may become fully realized.

Plato on Knowledge and Forms brings together a set of connected essays by Gail Fine, in her main area of research since the late 1970s: Plato's metaphysics and epistemology. She discusses central issues in Plato's metaphysics and epistemology, issues concerning the nature and extent of knowledge, and its relation to perception, sensibles, and forms; and issues concerning the nature of forms, such as whether they are universals or particulars, separate or immanent, and whether they are causes. A specially written introduction draws together the themes of the volume, which will reward the attention of anyone interested in Plato or in ancient metaphysics and epistemology.

An Innovating approach to Plato’s philosophy Through a careful survey of several significant Platonic texts, mainly focussing on the nature of knowledge, Essays on Plato’s Epistemology offers the reader a fresh and promising approach to Plato’s philosophy as a whole. From the very earliest reception of Plato’s philosophy, there has been a conflict between a dogmatic and a sceptical interpretation of his work and thought. Moreover, the two sides are often associated, respectively, with a metaphysical and an anti-metaphysical approach. This book, continuing a line of thought that is nowadays strongly present in the secondary literature – and also followed by the author in over thirty years of research –, maintains that a third way of thinking is required. Against the widespread view that an anti-dogmatic philosophy must go together with an anti-metaphysical stance, Trabattoni shows that for Plato, on the contrary, a sober and reasonable assessment of both the powers and limits of human reason relies on a proper metaphysical outlook.

The Theaetetus is one of the most widely studied of any of the Platonic dialogues because its dominant theme concerns the significant philosophical question, what is knowledge? In this new interpretation of the Theaetetus, Paul Stern provides the first full-length treatment of its political character in relationship to this dominant theme. Stern argues that this approach sheds significant light on the distinctiveness of the Socratic way of life, with respect to both its initial justification and its ultimate character.
