A Dictionary of Philosophy. By J. Radford Thomson. (R. D.
Dickinson.)—The plan of the book is to give the ipsissima verbs of philosophers. It represents a vast amount of reading, and doubtless will be found, on the whole, of some utility. It is possible that Pro- fessor Thomson would have achieved more success if he had not been weighted with the manuscript which he has edited for the press. His account of it describes just each a work as is only an apparent help to the person who has brought it into shape. Proportion is everything in a compilation of this kind, and proportion is very diffi- cult to attain except by a writer who can plan the whole work ab initio. We mast not, however, let our readers suppose that Professor Thomson has not done a great deal for his materials. The form of the book, too, is eminently convenient.
