Idealism
…Idealism, in the sense in which Objective Logic, as I understand it, is Idealism, may be defined as the doctrine that nothing exists but phenomena and what phenomena bring along with them and force upon us, that is Experience, including the reactions that experience feels and all that logically follows from experience by Deduction, Induction, and Hypothesis. And by us, we mean our neighbors, all that are embraced in the community, or society, very indefinite to our apprehension of which you and I are, as it were, histological cells.
…there are writers who limit consciousness to what we know of the past which they mistake for the present and who thus think it to be a question whether we are to say the external world alone is real and the internal world fiction or whether we shall say that the internal world is the real and the external world a fiction. While the true idealism, the pragmatistic idealism, is that reality consists in the future.
