“Paradox and counter-paradox” can rightfully be attributed to the golden fund of psychotherapeutic literature. This small book introduces the reader to the basic concepts and principles of the currently popular systematic approach to family psychotherapy. The authors provide a brilliant illustration of these principles through their own work with families in which one member suffers from mental illness. The book is addressed to practicing psychotherapists, psychiatrists, psychologists, as well as students of psychological and medical universities.
