Abstract

This chapter endeavours to demonstrate the relevance of the epistemological and metaphysical doctrines of books V, VI, and VII for Plato’s ethics. Firstly, the role played by the analysis of the sight-lovers theory and how it relates with the other aspects of this books is investigated. Secondly, the relevance of the doctrine of the Good as the supreme form and its analogy with the sun is evaluated. Thirdly, how the line and the cave fit with Plato’s discussion and the role they play is examined.
