The object of this interesting monograph is to draw attention to the similarity between schizophrenic and archaic experiences and thought. The author quotes cases to illustrate the various symptoms and then draws parallels from the thoughts, religious rites, taboos, magical acts, etc. of primitive races.

Special consideration is paid to the loss of the boundaries of the ego, as illustrated by fusion of the ego with the objective world or with other individuals, identifications, participations and so forth. The variations are too numerous to be discussed in a brief abstract and the book will well repay reading in full; but it is curious that there is no reference to such common classical symptoms as stereotypy, echopraxis, negativism and others.

Here and there the author supports his thesis by quotations from psycho-analytical literature.
