"Reason is not passion's slave." Rather, the author argues, reason appraises the cultural appropriateness of passion, thus directing our attitudinal behaviour. He refutes those theories of value which correspond philosophically to societies described by Jean-Jacques Rousseau: societies of "honour without virtue, reason without wisdom, pleasure without happiness." His argument, which takes into account traditional philosophic positions, is divided into five parts: Attitudes, Evaluation, Characterization, Culture, Morality.
