SOME OPINIONS OF THE PRESS
"One of the most important books that have been published during the last twenty-five years."—J.H. Muirhead in Literary Guide.
"This is truly a great book. It is one of supreme interest and importance to the student of Ethics, as well as to the student of Metaphysics. Every particular thing in it is delightful. The style, though often paradoxial, is singularly bright and attractive. It is hardly too much to say that the book is altogether the most important independent work on Metaphysics that has ever been written in English."—International Journal of Ethics.
"This book must be studied and reckoned with by all students of Metaphysics."—Guardian
