I feel that at bottom we are fighting the same fight, you a commander, I in the ranks. The position we are rescuing is "Tychism" and a really growing world. But whereas I have hitherto found no better way of defending Tychism than by affirming the spontaneous addition of _discrete_ elements of being (or their subtraction), thereby playing the game with intellectualist weapons, you set things straight at a single stroke by your fundamental conception of the continuously creative nature of reality. I think that one of your happiest strokes is your reduction of "finality," as usually taken, to its status alongside of efficient causality, as the twin-daughters of intellectualism. But this vaguer and truer finality restored to its rights will be a difficult thing to give content to. Altogether your reality lurks so in the background, in this book, that I am wondering whether you _couldn't_ give it any more development _in concreto_ here, or whether you perhaps were holding back developments, already in your possession, for a future volume. They are sure to come to you later anyhow, and to make a new volume; and altogether, the clash of these ideas of yours with the traditional ones will be sure to make sparks fly that will illuminate all sorts of dark places and bring innumerable new considerations into view. But the process may be slow, for the ideas are so revolutionary. Were it not for your style, your book might last 100 years unnoticed; but your way of writing is so absolutely commanding that your theories have to be attended to immediately. I feel very much in the dark still about the relations of the progressive to the regressive movement, and this great precipitate of nature subject to static categories. With a frank pluralism of _beings_ endowed with vital impulses you can get oppositions and compromises easily enough, and a stagnant deposit; but after my one reading I don't exactly "catch on" to the way in which the continuum of reality resists itself so as to have to act, etc., etc.
