"Certainly we know no higher game of chance than that for death and life. Every decision about this we watch with the utmost excitement, interest, and fear; for in our eyes all in all is at stake. On the other hand, nature, which never lies, but is always straightforward and open, speaks quite differently upon this theme, speaks like Krishna in the Bhagavadgita. What it says is: The death or the life of the individual is of no significance. It expresses this by the fact that it exposes the life of every brute, and even of man, to the most insignificant accidents without coming to the rescue. Consider the insect on your path; a slight, unconscious turning of your step is decisive as to its life or death. Look at the wood-snail, without any means of flight, of defence, of deception, of concealment, a ready prey for all. Look at the fish carelessly playing in the still open net; the frog restrained by its laziness from the flight which might save it; the bird that does not know of the falcon that soars above it; the sheep which the wolf eyes and examines from the thicket. All these, provided with little foresight, go about guilelessly among the dangers that threaten their existence every moment. Since now nature exposes its organisms, constructed with such inimitable skill, not only to the predatory instincts of the stronger, but also to the blindest chance, to the humour of every fool, the mischievousness of every child without reserve, it declares that the annihilation of these individuals is indifferent to it, does it no harm, has no significance, and that in these cases the effect is of no more importance than the cause. It says this very distinctly, and it does not lie; only it makes no comments on its utterances, but rather expresses them in the laconic style of an oracle. If now the all-mother sends forth her children without protection to a thousand threatening dangers, this can only be because she knows that if they fall they fall back into her womb, where they are safe; therefore their fall is a mere jest. Nature does not act otherwise with man than with the brutes. Therefore its declaration extends also to man: the life and death of the individual are indifferent to it. Accordingly, in a certain sense, they ought also to be indifferent to us, for we ourselves are indeed nature. Certainly, if only we saw deep enough, we would agree with nature, and regard life and death as indifferently as it does. Meanwhile, by means of reflection, we must attribute that carelessness and indifference of nature towards the life of the individuals to the fact that the destruction of such a phenomenon does not in the least affect its true and proper nature."
