the sufferings of living men, of real men. Divine zeal, preoccupation with the idea, finally dry up the tenderest souls, the most compassionate hearts, the sources of human love. Considering all that is, all that happens in the world from the point of view of eternity or of the abstract idea, they treat passing matters with disdain; but the whole life of real men, of men of flesh and bone, is composed only of passing matters; they themselves are only passing beings, who, once passed, are replaced by others likewise passing, but never to return in person. Alone permanent or relatively eternal in men is humanity, which steadily developing, grows richer in passing from one generation to another. I say relatively eternal, because, our planet once destroyed—it cannot fail to perish sooner or later, since everything which has begun must necessarily end—our planet once decomposed, to serve undoubtedly as an element of some new formation in the system of the universe, which alone is really eternal, who knows what will become of our whole human development? Nevertheless, the moment of this dissolution being an enormous distance in the future, we may properly consider humanity, relatively to the short duration of human life, as eternal. But this very fact of progressive humanity is real and living only through its manifestations at definite times, in definite places, in really living men, and not through its general idea.
The general idea is always an abstraction and, for that very reason, in some sort a negation of real life. I have stated in the Appendix that human thought and, in consequence of this, science can grasp and name only the general significance of real facts, their relations, their laws—in short, that which is permanent in their continual transformations—but never their material, individual side, palpitating,
