Originally published in 1958, this book contains the complete text of Plato's Philebus in an English translation. Among the last of the late Socratic dialogues, the central concern of the Philebus is the relative value of knowledge and pleasure. From this basis the text moves towards an understanding of human happiness and the constituent factors in 'the Good Life'. The dialogue consists of contributions by Socrates, Protarchus, and Philebus, with Socrates as the primary speaker. A detailed commentary is provided, offering key textual insights and explanations of conceptually difficult areas. This is a highly informative edition, that will be of value to anyone with an interest in Platonic thought and the Classical world.
