or decided upon some particular course of action; whether the motives that urged him in a particular direction were lofty or base, moral or egoistic, inspired by duty or by vanity, pure or impure? It is enough to make one lose one's head, as those scrupulous people are aware, who the more they attempt to perfect their examination of conscience the more they are confused. No other counsel can be offered to them than that of examining themselves certainly, but not overmuch, of looking rather ahead than behind, or only looking behind to the extent that it is necessary to look. We certainly know our own history and that of the world that surrounds us, but how little and how meagrely in comparison with our infinite desire for knowledge! The best way of ending this vexation of spirit is that which I have followed, that of pushing it to its extreme limit, and then of imagining for a moment that all the interrogations mentioned, together with the infinite others that could be mentioned, have been satisfied; satisfied as interrogations that continued to the infinite can be satisfied--that is to say, by affording an immediate answer to them, one after the other, and by causing the spirit to enter the path of a vertiginous process of satisfactions, always obtained to the infinite. Now, were all those interrogations satisfactorily answered, were we in possession of all the answers to them, what should we do? The road of progress to the infinite is as wide as that to hell, and if it does not lead to hell it certainly leads to the madhouse. And that infinite, which grows bigger the moment we first touch it, does not avail us; indeed it fills us with fear. Only the poor finite assists us, the determined, the concrete, which is grasped by thought and which lends itself as base for our existence and as point of departure for our action. Thus even were all the particular infinities of infinite history offered for the gratification of our desire, there would be nothing else left for us to do but to clear our minds of them, to _forget_ them, and to concentrate upon that particular point alone which corresponds to a problem and constitutes living, active history, _contemporary history_.
