After describing in his general introduction the evolution of psychiatry its difficulties, the prejudices that hamper it, and breadth of knowledge needful the author passes first to the psychological problems and stresses the need of distinguishing direct from indirect results of primary disturbance; discusses parallelism, dualism, etc.; is himself a realist; discusses the applications of psychology to the analysis of mental states of the insane and its difficulties.
