They worked hard to discover the vital secrets of the glands by opening up dogs and cutting out the glands, or tying up their ducts, or severing their nerves, thereby learning, negatively, that the governors of our vital forces do not hold their incessant conversations through the nerves, and, positively, how miserably a horribly injured dog can die, leaving us to infer that we shall probably perish likewise if we grudge our guineas to Harley Street. Lorenz Oken thought very hard to find out what was happening to the Holy Ghost, and thereby made a contribution of extraordinary importance to our understanding of uninjured creatures. The man who was scientific enough to see that the Holy Ghost is a scientific fact got easily in front of the blockheads who could only sin against it. Hence my uncle was turning his back on very respectable company when he derided Evolution, and would probably have recanted and apologized at once had anybody pointed out to him what a solecism he was committing.

The metaphysical side of Evolution was thus no novelty when Darwin arrived. Had Oken never lived, there would still have been millions of persons trained from their childhood to believe that we are continually urged upwards by a force called the Will of God. In 1819 Schopenhauer published his treatise on The World as Will, which is the metaphysical complement to Lamarck's natural history, as it demonstrates that the driving force behind Evolution is a will-to-live, and to live, as Christ said long before, more abundantly. And the earlier philosophers, from Plato to Leibniz, had kept the human mind open for the thought of the universe as one idea behind all its physically apprehensible transformations.

CORRECTED DATES FOR THE DISCOVERY OF EVOLUTION

All this, remember, is the state of things in the pre-Darwin period, which so many of us still think of as a pre-evolutionary period. Evolutionism was the rage before Queen Victoria came to the throne. To fix this chronology, let me repeat the story told by Weismann of the July revolution in Paris in 1830, when the French got rid of Charles the Tenth. Goethe was then still living; and a French friend of his called on him and found him wildly excited. 'What do you think of the great event?' said Goethe. 'The volcano is in eruption; and all is in flames. There can no longer be discussion with closed doors.' The Frenchman replied that no doubt it was a terrible business; but what could they expect with such a ministry and such a king? 'Stuff!' said Goethe: 'I am not thinking of these people at all, but of the open rupture in the French Academy between Cuvier and St Hilaire. It is of the utmost importance to science,' The rupture Goethe meant was about Evolution, Cuvier contending that there were four species, and St Hilaire that there was only one.

From 1830, when Darwin was an apparently unpromising lad of twenty-one, until 1859, when he turned the world upside down by his Origin of Species, there was a slump in Evolutionism. The first generation of its enthusiasts was ageing and dying out; and their successors were being taught from the Book of Genesis, just as Edward VI was (and Edward VII too, for that matter). Nobody who knew the theory was adding anything to it. This slump not only heightened the impression of entire novelty when Darwin brought the subject to the front again: it probably prevented him from realizing how much had been done before, even by his own grandfather, to whom he was accused of being unjust. Besides, he was not really carrying on the family business. He was an entirely original worker; and he was on a new tack, as we shall see presently. And he would not in any case have thought much, as a practical naturalist, of the more or less mystical intellectual speculations of the Deists of 1790-1830. Scientific workers were very tired of Deism just then. They had given up the riddle of the Great First Cause as insoluble, and were calling themselves, accordingly, Agnostics. They had turned from the inscrutable question of Why things existed, to the spade work of discovering What was really occurring in the world and How it really occurred.

With all his attention bent in this new direction, Darwin soon noticed that a good deal was occurring in an entirely unmystical and even unmeaning way of which the older speculative Deist-Evolutionists had taken little or no account. Nowadays, when we are turning in weary disgust and disillusion from Neo-Darwinism and Mechanism to Vitalism and Creative Evolution, it is difficult to imagine how this new departure of Darwin's could possibly have appealed to his contemporaries as exciting, agreeable, above all as hopeful. Let me therefore try to bring back something of the atmosphere of that time by describing a scene, very characteristic of its superstitions, in which I took what was then considered an unspeakably shocking part.

DEFYING THE LIGHTNING: A FRUSTRATED EXPERIMENT

One evening in 1878 or thereabouts, I, being then in my earliest twenties, was at a bachelor party of young men of the professional class in the house of a doctor in the Kensingtonian quarter of London. They fell to talking about religious revivals; and an anecdote was related of a man who, having incautiously scoffed at the mission of Messrs Moody and Sankey, a then famous firm of American evangelists, was subsequently carried home on a shutter, slain by divine vengeance as a blasphemer. A timid minority, without quite venturing to question the truth of the incident--for they naturally did not care to run the risk of going home on shutters themselves--nevertheless shewed a certain disposition to cavil at those who exulted in it; and something approaching to an argument began. At last it was alleged by the most evangelical of the disputants that Charles Bradlaugh, the most formidable atheist on the Secularist platform, had taken out his watch publicly and challenged the Almighty to strike him dead in five minutes if he really existed and disapproved of atheism. The leader of the cavillers, with great heat, repudiated this as a gross calumny, declaring that Bradlaugh had repeatedly and indignantly contradicted it, and implying that the atheist champion was far too pious a man to commit such a blasphemy. This exquisite confusion of ideas roused my sense of comedy.
