This is the second volume of a series of publications edited by L. Szondi who applied some psycho-analytical principles to his projective psychological methods and elaborated an 'experimental drive diagnosis'. (Triebdiagnostik.) Szondi views mental illnesses as 'diseases of destiny'. He defines them as 'a familial innate and inescapable choice of solutions of instinctual conflicts made by a person'. Dr. Stumper, who is the Director of the Luxemburg mental hospital, has in this book made the attempt to apply Szondi's psychology to almost the whole of clinical psychiatry. It has its own set of symbols and measures which tend to create the misleading impression of scientific exactitude.
