No one can help being struck by the perfect mastery of this wide field which is evinced all through the volume. Despite the compact form in which the material is presented, however, the progress of the development is apt to be obscured by the mass of detail. A good deal of this detail is not strictly relevant, if the aim was to trace the development of historical speculation. While the means are put into the reader's hands, he is left to make out the development for himself; and as it stands, the book is rather an invaluable mine of historical material than an exhibition of the progress of historical thought. A general survey of the whole field would have been most useful, and in omitting to do this the author has let slip an opportunity of bearing out his contention that nationality is one of the most potent factors in giving form to historical speculation.

He believes that "the standpoint of the reconciliation of all contradictions has been attained in the main by mankind in the Idealism founded by Kant, and wrought out to perfection by his disciple Schopenhauer." So thoroughly has this conviction taken possession of Dr. Deussen, that he never finds any teaching of the master to be contradictory, vague, or even insufficient, and never
