seek experience at its source, or rather above that decisive turn where, taking a bias in the direction of our utility, it becomes properly human experience. The impotence of speculative reason, as Kant has demonstrated it, is perhaps at bottom only the impotence of an intellect enslaved to certain necessities of bodily life, and concerned with a matter which man has had to disorganize for the satisfaction of his wants. Our knowledge of things would thus no longer be relative to the fundamental structure of our mind, but only to its superficial and acquired habits, to the contingent form which it derives from our bodily functions and from our lower needs. The relativity of knowledge may not, then, be definitive. By unmaking that which these needs have made, we may restore to intuition its original purity and so recover contact with the real.
This method presents, in its application, difficulties which are considerable and ever recurrent, because it demands for the solution of each new problem an entirely new effort. To give up certain habits of thinking, and even of perceiving, is far from easy: yet this is but the negative part of the work to be done; and when it is done, when we have placed ourselves at what we have called the turn of experience, when we have profited by the faint light which, illuminating the passage from the immediate to the useful, marks the dawn of our human experience, there still remains to be reconstituted, with the infinitely small elements which
