VII CRITICAL NOTICES. Philosophy, Its Scope and Relations ; an Introductory Course of Lectures. By the late HENRY SIDGWICK, Knightbridge Pro- fessor of Moral Philosophy in the University of Cambridge. London : Macmillan & Co. Limited, 1902. THIS volume forms a welcome supplement to the published works of its lamented author. It serves to define his position in reference to questions of general philosophy which are dealt with only in- cidentally, if at all, in his works on ethics and politics ; and there is an occasional intimacy in the expression of personal opinion in these lectures which one does not meet in the judicially balanced discussions in his other works.

This is probably the part of the volume which will attract most general attention. The last lecture which is somewhat detached from the rest has a title arising out of the definitions of the earlier lectures ' The
