Psychoanalysis―Lacan said―is a practical way to feel better. This book can be considered an explanation of this sentence. Based on two seminars held at San Francisco, it explains how psychoanalysis improves and enhances our style of enjoying life. A detailed study of the different ways in which words impact the body makes the dynamics of interpretations that animates the economy of "jouissances" in a psychoanalytic treatment easily understandable. Structured like most seminars in the Freudian Field, this study is self-contained, does not presuppose previous training, and in a short time pushes the reader to the current state of the art in the issue at hand.
