Sartre's study of Baudelaire is one of the more brilliant achievements off modern criticism. We may often disagree with his interpretations of the poet's personality, but we cannot fail to wonder at the mastery with which he presents his case. It is the case, quite patently, of an Existentialist who wishes to psychoanalyse a paramount literary figure in terms of his own beliefs. Perhaps Sartre's greatest contribution to Existentialism has been his own personality. He turned abstrations into a theory of psychoanalysis, grounded in man's creativity and opposed to Freudian determinism. Then he put the theory in practice in this book on Baudelaire, the greatest lyric poet of the age.
