This edition includes a substantial new preface by the author, in which he discusses repression, determinism, transference, and practical rationality, and offers a comparison of Aristotle and Lacan on the concept of desire. MacIntyre takes the opportunity to reflect both on the reviews and criticisms of the first edition and also on his own philosophical stance.
