and the concept of a history of pure experience such as that just explained, this statement from Professor James must seem of great consequence. What are the results of this for idealism? is the imperative question. I have done what I can to indicate the results that seem to me likely to follow, and my position is that the rejection of consciousness from the position it has hitherto occupied in metaphysics must follow from a candid inspection of pure experience, and that this cuts the ground from under the argument for idealism. I thus exhibit at least the presumption that the conception of a history of pure experience, which I take from Avenarius, is sound.
