To be sure, any attempt to draw lines of novel and absolute separation between writers of to-day and their immediate predecessors would be absurd and impossible, just as would be the attempt to force men who are still living and thinking and developing, into Procrustean beds of system and nomenclature. The history of the philosophy of the last half of this century constitutes a development as continuous and as logical as the philosophy of any similar period of years wherein men have thought persistently and truly upon the problems of life and mind. There were in the ’sixties men like Ulrici and Lotze (Renouvier, too, to some extent) who divined the limitations of a merely intellectual philosophy, and who saw clearly that the only way to effect a reconciliation between philosophy and science would be to apply philosophy itself to the problems of the life and thought of the time, just as we find, in 1893, Dr. Edward Caird writing, in his _Essays on Literature and Philosophy_, that “philosophy, in face of the increasing complexity of modern life, has a harder task laid upon it than ever was laid upon it before. It must emerge from the region of abstract principles and show itself able to deal with the manifold results of empirical science, giving to each of them its proper place and value.” Professor Campbell Fraser, while welcoming and sympathetically referring to (in his books upon Berkeley and Locke) the elements of positive value in English and German idealism, has throughout his life contended for the idea (expressed with greatest definiteness in his Gifford Lectures on _The Philosophy of Theism_) that “in man, as a self-conscious and self-determining _agent_,” is to be found the “best key we possess to the solution of the ultimate problem of the universe”; while Professor Sidgwick, by virtue of his captivating and ingenious pertinacity in confining philosophical speculation to the lines of the traditional English empiricism, and in keeping it free from the ensnaring subtleties of system and methodology, has exercised a healthful and corrective influence against the extremes alike of transcendentalism and naturalism. And it would be rash to maintain that all the younger men in philosophy show an intention to act upon the idea (expressed by Wundt, for instance, in his _Ethik_) that a metaphysic should build upon the facts of the moral life of man; although we find a “Neo-Hegelian” like Professor Mackenzie[201] saying that “even the wealth of our inner life depends rather on the width of our objective interests than on the intensity of our self-contemplation”; and an expounder of the ethics of dialectic evolution like Professor Muirhead quoting[202] with approval the thought expressed by George Eliot in the words, “The great world-struggle of developing thought is continually foreshadowed in the struggle of the affections seeking a justification for love and hope”; and a careful psychologist like Mr. Stout[203] deliberately penning
