This book presents the logic of the processes of mental life at all ages, from birth to old age.

The authors, coming from the field of psychoanalytic thought, first refer to the history of the subject's mental reality. They then present the primarily unconscious logics on which the forms of expression of psychopathology are based. The contribution of neuroscience in this field is also studied.

Finally, a projective approach completes this holistic effort and offers a method for mediating the subjectivity of the clinical psychologist.

Composed of the above components, this book is aimed at all those interested in an informed overall perspective on mental life and its pathologies, regardless of whether they are students, new professionals, or experienced psychologists.

This edition has been enriched with a new chapter on deviance and crime, along with a subsequent discussion on psychotherapy.
