Most creatures have a vague belief that a very precarious hazard, a kind of transparent membrane, divides death from love; and that the profound idea of nature demands that the giver of life should die at the moment of giving. Here this idea, whose memory lingers still over the kisses of man, is realised in its primal simplicity. No sooner has the union been accomplished than the male's abdomen opens, the organ detaches itself, dragging with it the mass of the entrails; the wings relax, and, as though struck by lightning, the emptied body turns and turns on itself and sinks down into the abyss.
The same idea that, before, in parthenogenesis, sacrificed the future of the hive to the unwonted multiplication of males, now sacrifices the male to the future of the hive.
This idea is always astounding; and the further we penetrate into it, the fewer do our certitudes become. Darwin, for instance, to take the man of all men who studied it the most methodically and most passionately, Darwin, though scarcely confessing it to himself, loses confidence at every step, and retreats before the unexpected and the irreconcilable. Would you have before you the nobly humiliating spectacle of human genius battling with infinite power, you have but to follow Darwin's endeavours to unravel the strange, incoherent, inconceivably mysterious laws of the sterility and fecundity of hybrids, or of the variations of specific and generic characters. Scarcely has he formulated a principle when numberless exceptions assail him; and this very principle, soon completely overwhelmed, is glad to find refuge in some corner, and preserve a shred of existence there under the title of an exception.
For the fact is that in hybridity, in variability (notably in the simultaneous variations known as correlations of growth), in instinct, in the processes of vital competition, in geologic succession and the geographic distribution of organised beings, in mutual affinities, as indeed in every other direction, the idea of nature reveals itself, in one and the same phenomenon and at the very same time, as circumspect and shiftless, niggard and prodigal, prudent and careless, fickle and stable, agitated and immovable, one and innumerable, magnificent and squalid. There lay open before her the immense and virgin fields of simplicity; she chose to people them with trivial errors, with petty contradictory laws that stray through existence like a flock of blind sheep. It is true that our eye, before which these things happen, can only reflect a reality proportionate to our needs and our stature; nor have we any warrant for believing that nature ever loses sight of her wandering results and causes.
In any event she will rarely permit them to stray too far, or approach illogical or dangerous regions. She disposes of two forces that never can err; and when the phenomenon shall have trespassed beyond certain limits, she will beckon to life or to death—which arrives, re-establishes order, and unconcernedly marks out the path afresh.

She eludes us on every side; she repudiates most of our rules and breaks our standards to pieces. On our right she sinks far beneath the level of our thoughts, on our left she towers mountain-high above them. She appears to be constantly blundering, no less in the world of her first experiments than in that of her last, of man. There she invests with her sanction the instincts of the obscure mass, the unconscious injustice of the multitude, the defeat of intelligence and virtue, the uninspired morality which urges on the great wave of the race, though manifestly inferior to the morality that could be conceived or desired by the minds composing the small and the clearer wave that ascends the other. And yet, can such a mind be wrong if it ask itself whether the whole truth—moral truths, therefore, as well as non-moral—had not better be sought in this chaos than in itself, where these truths would seem comparatively clear and precise?
The man who feels thus will never attempt to deny the reason or virtue of his ideal, hallowed by so many heroes and sages; but there are times when he will whisper to himself that this ideal has perhaps been formed at too great a distance from the enormous mass whose diverse beauty it would fain represent. He has, hitherto, legitimately feared that the attempt to adapt his morality to that of nature would risk the destruction of what was her masterpiece. But to-day he understands her a little better; and from some of her replies, which, though still vague, reveal an unexpected breadth, he has been enabled to seize a glimpse of a plan and an intellect vaster than could be conceived by his unaided imagination; wherefore he has grown less afraid, nor feels any longer the same imperious need of the refuge his own special virtue and reason afford him. He concludes that what is so great could surely teach nothing that would tend to lessen itself. He wonders whether the moment may not have arrived for submitting to a more judicious examination his convictions, his principles, and his dreams.
Once more, he has not the slightest desire to abandon his human ideal. That even which at first diverts him from this ideal teaches him to return to it. It were impossible for nature to give ill advice to a man who declines to include in the great scheme he is endeavouring to grasp, who declines to regard as sufficiently lofty to be definitive, any truth that is not at least as lofty as the truth he himself desires. Nothing shifts its place in his life save only to rise with him; and he knows he is rising when he finds himself drawing near to his ancient image of good. But all things transform themselves more freely in his thoughts; and he can descend with impunity, for he has the presentiment that numbers of successive valleys will lead him to the plateau that he expects. And, while he thus seeks for conviction, while his researches even conduct him to the very reverse of that which he loves, he directs his conduct by the most humanly beautiful truth, and clings to the one that provisionally seems to be highest. All that may add to beneficent virtue enters his heart at once; all that would tend to lessen it remaining there in suspense, like insoluble salts that change not till the hour for decisive experiment. He may accept an inferior truth, but before he will act in accordance therewith he will wait, if need be for centuries, until he perceive the connection this truth must possess with truths so infinite as to include and surpass all others.
