Once again the philosopher has to proceed in exactly the opposite direction. He has not to confine himself to ready-made business concepts, of the ordinary kind, suits cut to an average model, which fit nobody because they almost fit everybody; but he has to work to measure, incessantly renew his plant, continually recreate his mind, and meet each new problem with a fresh adaptive effort. He must not go from concepts to things, as if each of them were only the cutting-point of several concurrent generalities, an ideal centre of intersecting abstractions; on the contrary, he must go from things to concepts, incessantly creating new thoughts, and incessantly recasting the old. There could be no solution of the problem in a more or less ingenious mosaic or tessellation of rigid concepts, pre-existing to be employed. We need plastic fluid, supple and living concepts, capable of being continually modelled on reality, of delicately following its infinite curves. The philosopher's task is then to create concepts much more than to combine them. And each of the concepts he creates must remain open and adjustable, ready for the necessary renewal and adaptation, like a method or a programme: it must be the arrow pointing to a path which descends from intuition to language, not a boundary marking a terminus. In this way only does philosophy remain what it ought to be: the examination into the consciousness of the human mind, the effort towards enlargement and depth which it attempts unremittingly, in order to advance beyond its present intellectual condition.
