Description

IN Hallucinations and Illusions Mr. Edmund Parish presents a scholarly study of an important problem. This study, he tells us, grew out of an examination of the International Census of Waking Hallucinations in the Sane. In the English edition -- the German is four years old -- he has added new matter and recast certain chapters. The book may now be characterized as a sustained effort to set forth, in the light of the most recent psychical and neurological researches, the "common organic principle which, under whatever diversity of conditions, underlies alike normal and fallacious perception". Every leading proposition of the book lies in a matrix of carefully collated authorities. There is nothing vague, timid or unjustified. From definition to conclusion, the exposition is an orderly sequence of relevant considerations. As a result, Mr. Parish's book is at once an important contribution to the psychology of perception and an admirable introduction to the. theory of insanity. Henceforward the student of hallucinations. and illusions-that ancient battle-ground of futile distinctions -- will do well to begin here and work backwards. He will find the profit of following a well-considered generalization through a vast amount of detail. This generalization is -- that Dissociation of Consciousness is the condition precedent of all forms of fallacious perception. Dissociation psychological and physiological-offers a scientific formula for every variety of hallucination and illusion. It leaves the detailed determination of causes to the practical alienist. If this generalization can be substantiated, it will constitute a formidable instrument in the criticism of new researches. Even if it is not demonstrated, it will, as the sequel shows, form a good guiding hypothesis.... --Mind, Volume VII. -- 1898
