Originally published in 1979, Plato's Dialogue on Friendship is the first book-length interpretation of the Lysis in English, offering both a full analysis and a literal translation of this frequently neglected Platonic dialogue. David Bolotin interprets the Lysis as an important work in its own right and places it in the context of Plato's other writings. He attempts to show that despite Socrates' apparent failure to discover what a friend is, a coherent understanding of friendship emerges in the Lysis. His commentary follows the dialogue closely, and his interpretation unfolds gradually, as he is providing a detailed summary of the Lysis itself. Mr. Bolotin's translation captures the playfulness and rich ambiguities of the Lysis and its effectiveness as conversational drama. His book, written with precision and clarity, should be useful to students of political philosophy and ancient philosophy.
