'He has written an important book which worthily extends the work of such writers as Arthur Adkins (Merit and Responsibility, 1960) and Eric Dodds (The Greeks and the Irrational, 1951) ... is scrupulous and acute, and discussion of primary evidence is buttressed by a massive array of well-organised secondary material. The texture of Cairn's scholarship is dense, but his style is clear and direct ... this book is a very distinguished achievement.'Times Higher Education Supplement
