the camelopard (by children, cammyleopard). I do not remember how this animal imposed himself illustratively on the Evolution controversy; but there was no getting away from him then; and I am old-fashioned enough to be unable to get away from him now. How did he come by his long neck? Lamarck would have said, by wanting to get at the tender leaves high up on the tree, and trying until he succeeded in wishing the necessary length of neck into existence. Another answer was also possible: namely, that some prehistoric stockbreeder, wishing to produce a natural curiosity, selected the longest-necked animals he could find, and bred from them until at last an animal with an abnormally long neck was evolved by intentional selection, just as the race-horse or the fantail pigeon has been evolved. Both these explanations, you will observe, involve consciousness, will, design, purpose, either on the part of the animal itself or on the part of a superior intelligence controlling its destiny. Darwin pointed out—and this and no more was Darwin's famous discovery—that a third explanation, involving neither will nor purpose nor design either in the animal or anyone else, was on the cards. If your neck is too short to reach your food, you die. That may be the simple explanation of the fact that all the surviving animals that feed on foliage have necks or trunks long enough to reach it. So bang goes your belief that the necks must have been designed to reach the food. But Lamarck did not believe that the necks were so designed in the beginning: he believed that the long necks were evolved by wanting and trying. Not necessarily, said Darwin. Consider the effect on the giraffes of the natural multiplication of their numbers, as insisted on by Malthus. Suppose the average height of the foliage-eating animals is four feet, and that they increase in numbers until a time comes when all the trees are eaten away to within four feet of the ground. Then the animals who happen to be an inch or two short of the average will die of starvation. All the animals who happen to be an inch or so above the average will be better fed and stronger than the others. They will secure the strongest and tallest mates; and their progeny will survive whilst the average ones and the sub-average ones will die out. This process, by which the species gains, say, an inch in reach, will repeat itself until the giraffe's neck is so long that he can always find food enough within his reach, at which point, of course, the selective process stops and the length of the giraffe's neck stops with it. Otherwise, he would grow until he could browse off the trees in the moon. And this, mark you, without the intervention of any stockbreeder, human or divine, and without will, purpose, design, or even consciousness beyond the blind will to satisfy hunger. It is true that this blind will, being in effect a will to live, gives away the whole case; but still, as compared to the open-eyed intelligent wanting and trying of Lamarck, the Darwinian process may be described as a chapter of accidents. As such, it seems simple, because you do not at first realize all that it involves. But when its whole significance dawns on you, your heart sinks into a heap of sand within you. There is a hideous fatalism about it, a ghastly and damnable reduction of beauty and intelligence, of strength and purpose, of honor and aspiration, to such casually picturesque changes as an avalanche may make in a mountain landscape, or a railway accident in a human figure. To call this Natural Selection is a blasphemy, possible to many for whom Nature is nothing but a casual aggregation of inert and dead matter, but eternally impossible to the spirits and souls of the righteous. If it be no blasphemy, but a truth of science, then the stars of heaven, the showers and dew, the winter and summer, the fire and heat, the mountains and hills, may no longer be called to exalt the Lord with us by praise; their work is to modify all things by blindly starving and murdering everything that is not lucky enough to survive in the universal struggle for hogwash.
THE BRINK OF THE BOTTOMLESS PIT
Thus did the neck of the giraffe reach out across the whole heavens and make men believe that what they saw there was a gloaming of the gods. For if this sort of selection could turn an antelope into a giraffe, it could conceivably turn a pond full of amoebas into the French Academy. Though Lamarck's way, the way of life, will, aspiration, and achievement, remained still possible, this newly shewn way of hunger, death, stupidity, delusion, chance, and bare survival was also possible: was indeed most certainly the way in which many apparently intelligently designed transformations had actually come to pass. Had I not preluded with the apparently idle story of my revival of the controversial methods of Elijah, I should be asked how it was that the explorer who opened up this gulf of despair, far from being stoned or crucified as the destroyer of the honor of the race and the purpose of the world, was hailed as Deliverer, Savior, Prophet, Redeemer, Enlightener, Rescuer, Hope Giver, and Epoch Maker; whilst poor Lamarck was swept aside as a crude and exploded guesser hardly worthy to be named as his erroneous forerunner. In the light of my anecdote, the explanation is obvious. The first thing the gulf did was to swallow up Paley, and the Disorderly Designer, and Shelley's Almighty Fiend, and all the rest of the pseudo-religious rubbish that had blocked every upward and onward path since the hopes of men had turned to Science as their true Savior. It seemed such a convenient grave that nobody at first noticed that it was nothing less than the bottomless pit, now become a very real terror. For though Darwin left a path round it for his soul, his followers presently dug it right across the whole width of the way. Yet for the moment, there was nothing but wild rejoicing: a sort of scientific mafficking. We had been so oppressed by the notion that everything that happened in the world was the arbitrary personal act of an arbitrary personal god of dangerously jealous and cruel personal character, so that even the relief of the pains of childbirth and the operating table by chloroform was objected to as an interference with his arrangements which he would probably resent, that we just jumped at Darwin. When Napoleon was asked what would happen when he died, he said that Europe would express its intense relief with a great 'Ouf!': Well, when Darwin killed the god who objected to chloroform, everybody who had ever thought about it said 'Ouf!' Paley was buried fathoms deep with his watch, now fully accounted for without any divine artificer at all. We were so glad to be rid of both that we never gave a thought to the consequences. When a prisoner sees the door of his dungeon open, he dashes for it without stopping to think where he shall get his dinner outside. The moment we found that we could do without Shelley's almighty fiend intellectually, he went into the gulf that seemed only a dustbin with a suddenness that made our own lives one of the most astonishing periods in history. If I had told that uncle of mine that within thirty years from the date of our conversation I should be exposing myself to suspicions of the grossest superstition by questioning the sufficiency of Darwin; maintaining the reality of the Holy Ghost; declaring that the phenomenon of the Word becoming Flesh was occurring daily, he would have regarded me as the most extravagant madman our family had ever produced. Yet it was so. In 1906 I might have vituperated Jehovah more heartily than ever Shelley did without eliciting a protest in any circle of thinkers, or shocking any public audience accustomed to modern discussion; but when I described Darwin as 'an intelligent and industrious pigeon fancier,' that blasphemous levity, as it seemed, was received with horror and indignation. The tide has now turned; and every puny whipster may say what he likes about Darwin; but anyone who wants to know what it was to be a Lamarckian during the last quarter of the nineteenth century has only to read Mr. Festing Jones's memoir of Samuel Butler to learn how completely even a man of genius could isolate himself by antagonizing Darwin on the one hand and the Church on the other.
WHY DARWIN CONVERTED THE CROWD
I am well aware that in describing the effect of Darwin's discovery on naturalists and on persons capable of serious reflection on the nature and attributes of God, I am leaving the vast mass of the British public out of account. I have pointed out elsewhere that the British nation does not consist of atheists and Plymouth Brothers; and I am not now going to pretend that it ever consisted of Darwinians and Lamarckians. The average citizen is irreligious and unscientific: you talk to him about cricket and golf, market prices and party politics, not about evolution and relativity, transubstantiation and predestination. Nothing will knock into his head the fateful distinction between Evolution as promulgated by Erasmus Darwin, and Circumstantial (so-called
