" We commend the book to all students of psychology. It should be 

 added that the translation has been well done, and, unlike many from the 

 German, is exceedingly readable, save in the more subtle philosophical 

 portions, even to the ordinary reader." Nonconformist and Independent. 



" We could wish to follow up his fascinating speculations further in 

 their bearings on the questions of immortality, ethics, and all the most im- 

 portant problems of the world. Du Prel's speculations differ from all others 

 of the kind in this, that they purport to rest upon a basis of demonstrable 

 facts. Whether these facts are genuine is a question worthy of more atten- 

 tion than it has hitherto received. He has the further advantage of being 

 well equipped scientifically as well as metaphysically. Darwin and the 

 scientists are as familiar to him as Kant, Schopenhauer, and Hartmann. 

 Whether he has succeeded in pointing out a new path of psychological 

 investigation it would be too soon to say definitely. But he has produced 

 a very remarkable and striking book, and all who take an interest in these 

 questions will do well to read it in Mr Massey's excellent translation."

' ' If the members of the Psychical Society have not already mastered the 

 ' Philosophic der Mystik ' of Baron Carl du Prel, doctor of philosophy, they 

 have to hand a translation by C. C. Massey, in two volumes, which they can 

 ill afford to neglect. This philosophic treatise on dream phenomena deals 

 with Mysticism not as something unknowable, or isolated from experience, 

 but as organically related with ' the totality of things.' The dream-life, our 

 author undertakes to show, is as worthy of study as the waking life. . . . Dr 

 du Prel's work teems with illustrations, derived from innumerable sources, of 

 the wonders of somnambulism and clairvoyance, of the restorative virtue of 

 the somnambulist's sleep, the health-prescriptions and cures of the clairvoyant, 

 many of which must put the best physician to the blush. Of ' evidence,' in 

 fact, there is more than sufficient to illustrate the dualism of consciousness, 

 and to exercise alike the open-minded and the credulous." Saturday Review. 



' ' The exceedingly difficult and interesting questions relating to memory 

 are discussed with great ability on the line of this double consciousness. The 

 apparent permanence of all impressions as shown by the reproduction of the 

 most distant, complicated, and improbable in sleep or trance the extraordi- 

 nary gaps in the life of a somnambule, caused by the double state, are described 

 most carefully." Scots Observer. 



"Mr C. C. Massey has sensibly enriched the student of transcendental 

 philosophy by translating Du Prel's 'Philosophy of Mysticism.' . . . 

 This translation, a piece of excellent work in a somewhat difficult field of 

 labour, will be welcome to every one who is interested in the collateral 

 development of German transcendental philosophy." Scotsman. 



" Speculations ingenious and far-reaching. . . . We thank Mr Massey 

 for the general clearness of his rendering and for his lucid and persuasive 

 introduction. . . . We cannot help feeling some interest and sympathy in 

 the Baron's futile ingenuities and innocently boastful eclecticism : he is so 

 bitter an opponent of narrow eighteenth century Aufklarung, and himself 

 such a charming type of nineteenth century Aufklarung; he has read and 

 misunderstood so much ; he is so guilelessly persuaded he possesses the 

 winnowing fan that can sift the true from the false in the beliefs of all ages ; 

 he is altogether so superior, so lucid and unbiassed an intellect, a pupil in all 

 schools, and the judge of all." Athenaum.
