The relapses between the efforts to acquire a habit are important because, as we have seen, they recur not only from effort to effort in the case of the individual, but from generation to generation in the case of the race. This relapsing from generation to generation is an invariable characteristic of the evolutionary process. For instance, Raphael, though descended from eight uninterrupted generations of painters, had to learn to paint apparently as if no Sanzio had ever handled a brush before. But he had also to learn to breathe, and digest, and circulate his blood. Although his father and mother were fully grown adults when he was conceived, he was not conceived or even born fully grown: he had to go back and begin as a speck of protoplasm, and to struggle through an embryonic lifetime, during part of which he was indistinguishable from an embryonic dog, and had neither a skull nor a backbone. When he at last acquired these articles, he was for some time doubtful whether he was a bird or a fish. He had to compress untold centuries of development into nine months before he was human enough to break loose as an independent being. And even then he was still so incomplete that his parents might well have exclaimed 'Good Heavens! have you learnt nothing from our experience that you come into the world in this ridiculously elementary state? Why cant you talk and walk and paint and behave decently?' To that question Baby Raphael had no answer. All he could have said was that this is how evolution or transformation happens. The time may come when the same force that compressed the development of millions of years into nine months may pack many more millions into even a shorter space; so that Raphaels may be born painters as they are now born breathers and blood circulators. But they will still begin as specks of protoplasm, and acquire the faculty of painting in their mother's womb at quite a late stage of their embryonic life. They must recapitulate the history of mankind in their own persons, however briefly they may condense it.

Nothing was so astonishing and significant in the discoveries of the embryologists, nor anything so absurdly little appreciated, as this recapitulation, as it is now called: this power of hurrying up into months a process which was once so long and tedious that the mere contemplation of it is unendurable by men whose span of life is three-score-and-ten. It widened human possibilities to the extent of enabling us to hope that the most prolonged and difficult operation of our minds may yet become instantaneous, or, as we call it, instinctive. It also directed our attention to examples of this packing up of centuries into seconds which were staring us in the face in all directions. As I write these lines the newspapers are occupied by the exploits of a child of eight, who has just defeated twenty adult chess players in twenty games played simultaneously, and has been able afterwards to reconstruct all the twenty games without any apparent effort of memory. Most people, including myself, play chess (when they play it at all) from hand to mouth, and can hardly recall the last move but one, or foresee the next but two. Also, when I have to make an arithmetical calculation, I have to do it step by step with pencil and paper, slowly, reluctantly, and with so little confidence in the result that I dare not act on it without 'proving' the sum by a further calculation involving more ciphering. But there are men who can neither read, write, nor cipher, to whom the answer to such sums as I can do is instantly obvious without any conscious calculation at all; and the result is infallible. Yet some of these natural arithmeticians have but a small vocabulary; are at a loss when they have to find words for any but the simplest everyday occasions; and cannot for the life of them describe mechanical operations which they perform daily in the course of their trade; whereas to me the whole vocabulary of English literature, from Shakespear to the latest edition of the Encyclopaedia Britannica, is so completely and instantaneously at my call that I have never had to consult even a thesaurus except once or twice when for some reason I wanted a third or fourth synonym. Again, though I have tried and failed to draw recognizable portraits of persons I have seen every day for years, Mr Bernard Partridge, having seen a man once, will, without more strain than is involved in eating a sandwich, draw him to the life. The keyboard of a piano is a device I have never been able to master; yet Mr Cyril Scott uses it exactly as I use my own fingers; and to Sir Edward Elgar an orchestral score is as instantaneously intelligible at sight as a page of Shakespear is to me. One man cannot, after trying for years, finger the flute fluently. Another will take up a flute with a newly invented arrangement of keys on it, and play it at once with hardly a mistake. We find people to whom writing is so difficult that they prefer to sign their name with a mark, and beside them men who master systems of shorthand and improvise new systems of their own as easily as they learnt the alphabet. These contrasts are to be seen on all hands, and have nothing to do with variations in general intelligence, nor even in the specialized intelligence proper to the faculty in question: for example, no composer or dramatic poet has ever pretended to be able to perform all the parts he writes for the singers, actors, and players who are his executants. One might as well expect Napoleon to be a fencer, or the Astronomer Royal to know how many beans make five any better than his bookkeeper. Even exceptional command of language does not imply the possession of ideas to express; Mezzofanti, the master of fifty-eight languages, had less to say in them than Shakespear with his little Latin and less Greek; and public life is the paradise of voluble windbags.

All these examples, which might be multiplied by millions, are cases in which a long, laborious, conscious, detailed process of acquirement has been condensed into an instinctive and unconscious inborn one. Factors which formerly had to be considered one by one in succession are integrated into what seems a single simple factor. Chains of hardly soluble problems have coalesced in one problem which solves itself the moment it is raised. What is more, they have been pushed back (or forward, if you like) from post-natal to pre-natal ones. The child in the womb may take some time over them; but it is a miraculously shortened time.

The time phenomena involved are curious, and suggest that we are either wrong about our history or else that we enormously exaggerate the periods required for the pre-natal acquirement of habits. In the nineteenth century we talked very glibly about geological periods, and flung millions of eons about in the most lordly manner in our reaction against Archbishop Ussher's chronology. We had a craze for big figures, and positively liked to believe that the progress made by the child in the womb in a month was represented in prehistoric time by ages and ages. We insisted that Evolution advanced more slowly than any snail ever crawled, and that Nature does not proceed by leaps and bounds. This was all very well as long as we were dealing with such acquired habits as breathing or digestion. It was possible to believe that dozens of epochs had gone to the slow building up of these habits. But when we have to consider the case of a man born not only as an accomplished metabolist, but with such an aptitude for shorthand and keyboard manipulation that he is a stenographer or pianist at least five sixths ready-made as soon as he can control his hands intelligently, we are forced to suspect either that keyboards and shorthand are older inventions than we suppose, or else that acquirements can be assimilated and stored as congenital qualifications in a shorter time than we think; so that, as between Lyell and Archbishop Ussher, the laugh may not be with Lyell quite so uproariously as it seemed fifty years ago.
