It is but the old story, of a useful practice first becoming a method, then a habit, and finally a tyranny that defeats the end it was used for. Concepts, first employed to make things intelligible, are clung to even when they make them unintelligible. Thus it comes that when once you have conceived things as 'independent,' you must proceed to deny the possibility of any connexion whatever among them, because the notion of connexion is not contained in the definition of independence. For a like reason you must deny any possible forms or modes of unity among things which you have begun by defining as a 'many.' We have cast a glance at Hegel's and Bradley's use of this sort of reasoning, and you will remember Sigwart's epigram that according to it a horseman can never in his life go on foot, or a photographer ever do anything but photograph. The classic extreme in this direction is the denial of the possibility of change, and the consequent branding of the world of change as unreal, by certain philosophers. The definition of A is changeless, so is the definition of B. The one definition cannot change into the other, so the notion that a concrete thing A should change into another concrete thing B is made Out to be contrary to reason. In Mr. Bradley's difficulty in seeing how sugar can be sweet intellectualism outstrips itself and becomes openly a sort of verbalism. Sugar is just sugar and sweet is just sweet; neither is the other; nor can the word 'is' ever be understood to join any subject to its predicate rationally. Nothing 'between' things can connect them, for 'between' is just that third thing, 'between,' and would need itself to be connected to the first and second things by two still finer betweens, and so on ad infinitum. The particular intellectualistic difficulty that had held my own thought so long in a vise was, as we have seen at such tedious length, the impossibility of understanding how 'your' experience and 'mine,' which 'as such' are defined as not conscious of each other, can nevertheless at the same time be members of a world-experience defined expressly as having all its parts co-conscious, or known together. The definitions are contradictory, so the things defined can in no way be united. You see how unintelligible intellectualism here seems to make the world of our most accomplished philosophers. Neither as they use it nor as we use it does it do anything but make nature look irrational and seem impossible. In my next lecture, using Bergson as my principal topic, I shall enter into more concrete details and try, by giving up intellectualism frankly, to make, if not the world, at least my own general thesis, less unintelligible.
