The Commens Dictionary
Quote from ‘Letters to William James’
…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.
