The other interpretation, on the contrary, offers us no morality, no ideal superior to our instinct, no aim situate outside ourselves and no horizon other than space. Or else, if we could derive a morality from the only synthetic theory that has sprung from the innumerable experimental and fragmentary statements which form the imposing but dumb mass of the conquests of science, I mean the theory of evolution, it would be the horrible and monstrous morality of nature, that is to say, the adaptation of the species to the environment, the triumph of the strongest and all the crimes necessary to the struggle of life. Now this morality, which does, in the meanwhile, appear to be another certainty, the essential morality of all earthly life, since it inspires the actions of agile and ephemeral man as well as the slow movements of the undying crystals: this morality would soon become fatal to mankind if it were practised to an extreme. All religions, all philosophies, the counsels of gods and wise men have had no other object than to introduce into this overheated environment, which, if it were pure, would probably dissolve our species, elements that should reduce its virulence. These were, more particularly, a belief in just and dread gods, a hope of reward and a fear of eternal punishment. There were also neutral matters and antidotes, for which, with a somewhat curious foresight, nature had reserved a place in our own hearts: I mean goodness, pity, a sense of justice. Wherefore, this intolerant and exclusive environment, which was to be our natural and normal environment, was never and probably never will be pure. Be this as it may, the state in which it is to-day offers a strange and noteworthy spectacle. It is fretting, bubbling and being precipitated like a fluid into which chance has let fall a few drops of some unknown reagent. The compensating principles which religion had added to it are gradually evaporating and being eliminated at the top, while at the bottom they are coagulating into a thick and inactive mass. But, in proportion as these disappear, the purely human antidotes, although oxydized through and through by the elimination of the religious elements, gain greater vigour and seem to exert themselves to maintain the standard of the mixture in which the human species is being cultivated by an obscure destiny. Pending the arrival of as yet mysterious auxiliaries, they occupy the place abandoned by the evaporating forces. V
