No doubt this correlation of the two impulsions is simply a problem advanced by reason, and which man will only be able to solve in the perfection of his being. It is in the strictest signification of the term: the idea of his humanity; accordingly, it is an infinite to which he can approach nearer and nearer in the course of time, but without ever reaching it. "He ought not to aim at form to the injury of reality, nor to reality to the detriment of the form. He must rather seek the absolute being by means of a determinate being, and the determinate being by means of an infinite being. He must set the world before him because he is a person, and he must be a person because he has the world before him. He must feel because he has a consciousness of himself, and he must have a consciousness of himself because he feels." It is only in conformity with this idea that he is a man in the full sense of the word; but he cannot be convinced of this so long as he gives himself up exclusively to one of these two impulsions, or only satisfies them one after the other. For as long as he only feels, his absolute personality and existence remain a mystery to him, and as long as he only thinks, his condition or existence in time escapes him. But if there were cases in which he could have at once this twofold experience in which he would have the consciousness of his freedom and the feeling of his existence together, in which he would simultaneously feel as matter and know himself as spirit, in such cases, and in such only, would he have a complete intuition of his humanity, and the object that would procure him this intuition would be a symbol of his accomplished destiny, and consequently serve to express the infinite to him--since this destination can only be fulfilled in the fulness of time. Presuming that cases of this kind could present themselves in experience, they would awake in him a new impulsion, which, precisely because the two other impulsions would co-operate in it, would be opposed to each of them taken in isolation, and might, with good grounds, be taken for a new impulsion. The sensuous impulsion requires that there should be change, that time should have contents; the formal impulsion requires that time should be suppressed, that there should be no change. Consequently, the impulsion in which both of the others act in concert--allow me to call it the instinct of play, till I explain the term--the instinct of play would have as its object to suppress time in time to conciliate the state of transition or becoming with the absolute being, change with identity. The sensuous instinct wishes to be determined, it wishes to receive an object; the formal instinct wishes to determine itself, it wishes to produce an object. Therefore the instinct of play will endeavor to receive as it would itself have produced, and to produce as it aspires to receive.
