NEW BOOKS. '271 steadily in view the essential unity of the subject. For Prof. Laurie claims'to have established an unbroken chain of rational interdependence from his first principles to his ultimate rules and applications. The contrast between the attuitional and rational planes is made to produce valuable applications ; and the exclusion of memory and imagination from the " dynamic process of mind as such," gets rid of much of the confusion that the usual classification of those modes of being conscious involves. The practical identification of reason and will is at first startling, but after all we see no cause to refuse our author's invitation when he begs us " to go deeper down and see in Will the root, possibility and essence of this very endowment which in its fulness, that is to say, as including the form in which it moves to its end, viz., knowing and willing, is called Reason" (p. 117). We doubt, all the same, whether he would be willing to let us make a general application of this system of Concept-interpretation, after the manner of Prof. James. It is in- teresting to note that though Prof. Laurie has adopted a new principle, and has followed entirely his own method, he has reached a body of sound doctrine in education which cannot fail to commend itself to all experts in that subject.

These works are severely practical in character. Only in the last, and there only in an appendix, do we find a theory : the theory of an astral fluid, respired by the heavenly bodies, and absorbed by the Pacinian corpuscles of the human hand. Apart from this contribution to philo- sophy, the significance of the books lies in their existence and selling power. As indices of the present state of folk -psychology in a civilised nation, they may find mention in a psychological journal.

Veitch's " Introduction " is omitted, and a preface written in popular terms by T. J. McCormack substituted for it. The book is well printed, and should prove extremely useful. The reprint of Do Morgan's Illustrations has been reparagraphed, fur- nished with descriptive sub-headings, and carefully indexed. Miss Frances Welby's translation of Ribot's General Ideas is accurate and readable. Mr. Stanley's Psychology deals cursorily with the definition of psychology, knowing (sensation and perception, memory, ideation and introspection), feeling and will, and ' special ' psychology.
