The best testimony to the profound and far-reaching character of the scientific discussions of the Origin of Species is found in the fact that both Hooker and Huxley, in spite of their wide knowledge and long intercourse with Darwin, found the work, so condensed were its reasonings, a 'very hard book' to read, one on which it was difficult to pronounce a judgment till after several perusals!
It would be idle to speculate at the present day whether the cause of Evolution would have been better served by the publication, as Darwin at one time proposed, of a 'Preliminary Essay,' like that of 1844, or by the great work, which had been commenced and half completed in 1858, rather than by the 'abstract,' in which the theory of Natural Selection was in the end presented to the world. Probably the more moderate dimensions of the Origin of Species made it far better suited for the general reader; while the condensation which was necessitated did not in the end militate against its influence with men of science. It will I think be now generally conceded that the great success of this grand work was fully deserved. A subject of such complexity as that which it dealt with could only be adequately discussed in a manner that would demand careful attention and thought on the part of the reader; and Darwin's well-weighed words, carefully balanced sentences, and guarded reservations are admirably adapted to the accomplishment of the difficult task he had undertaken. The Origin of Species has been read by the millions with pleasure, and, at the same time, by the deepest thinkers of the age with conviction.
It is scarcely possible to refer to the literary style of Darwin's work without a reference to a misconception arising from that very candid analysis of his characteristics which he wrote for the satisfaction of his family, but which has happily been given to the world by his son. In his early life Darwin was exceedingly fond of music, and took such delight in good literature, especially poetry, that when on his journeys in South America he found himself able to carry only one book with him, the work chosen was the poems of Milton—the former student of his own Christ's College, Cambridge. But towards the end of his life, Darwin had sadly to confess that he found that he had quite lost the capacity of enjoying either music or the noblest works of literature.
Some have argued that Darwin's scientific labours must have actually proved destructive to his artistic and literary tastes, and have even gone so far as to assert—in spite of numerous examples to the contrary—that there is a natural antithesis between the mental conditions that respectively favour scientific and artistic excellence.
But I think there is a very simple explanation of the loss by Darwin of his powers of enjoyment of music and poetry, a loss which he evidently greatly deplored. His scientific undertaking was so gigantic, and, at the same time, his health was so broken and precarious, that he felt his only chance of success lay in utilizing, for the tasks before him, every moment that he was free from acute suffering and retained any power of working. Consequently, when the self-imposed task of each day was completed, he found himself in a state of mental collapse. Now to appreciate the beauties of fine music or the work of a great writer certainly demands that the mind should be fresh and unjaded, whereas, at the only times Darwin had for relaxation, he was quite unfitted for these higher delights. We are not surprised then to learn that he sought and found relief in listening to his wife's reading of some pleasant novel or in the nightly game of backgammon, as the only means of resting his wearied brain.
No one who had the privilege of conversing with Darwin in his later years can doubt of his having retained to the end the full possession of his refined tastes as well as his great mental powers. His love for and sympathy with every movement tending to progress—especially in the scientific and educational world—his devotion to his friends, with no little indulgence of indignation for what he thought false or mean in others, these were his conspicuous characteristics, and they were combined with a gentle playfulness and sense of humour, which made him the most delightful and loveable of companions.
CHAPTER XI
THE INFLUENCE OF DARWIN'S WORKS
In two essays 'On the Coming of Age of the Origin of Species[134],' and 'On the Reception of the Origin of Species[135],' published in 1880 and 1887 respectively, Huxley has discussed the course of events following the publication of Darwin's great work, he having the advantage of being one of the chief actors in those events. There is a striking parallelism between the manner that the Principles of Geology had been received thirty years earlier, and the way that the Origin of Species was met, both by Darwin's scientific contemporaries and the reading public.
