marked as before.’[353] And thus the long series of packed, closely printed volumes forms an amazing record of a life of zealous, persistent, curious experimentation from beginning to end. III Now let us look a little more closely at the stuff and quality of Darwin’s logical processes, considered as such. He himself often complains of the slowness and difficulty of his thinking. It is hard for him to arrange his thoughts, he says, hard for him to get them into the lucid and effective order which carries conviction with it, almost enforces conviction by the power of its own movement. He says of one of his critics: ‘He admits to a certain extent Natural Selection, yet I am sure does not understand me. It is strange that very few do, and I am become quite convinced that I must be an extremely bad explainer.’[354] It is worth while to note the comments of Huxley, as one of Darwin’s staunchest friends and supporters, on his reasoning faculty and processes. When Romanes lauds Darwin’s colossal intellect, Huxley is inclined to protest: ‘Colossal does not seem to me to be the right epithet for Darwin’s intellect. He had a clear, rapid intelligence, a great memory, a vivid imagination, and what made his greatness was the strict subordination of all these to the love of truth.’[355] Elsewhere Huxley adds: ‘Exposition was not Darwin’s forte—and his English is sometimes wonderful. But there is a marvelous dumb sagacity about him and he gets to truth by ways as dark as those of the Heathen Chinee.’[356] Of ‘The Origin of Species’ Huxley writes: ‘It is one of the hardest books to understand thoroughly that I know of.’[357] And again, more amply: ‘Long occupation with the work has led the present writer to believe that “The Origin of Species” is one of the hardest of books to master, and he is justified in this conviction by observing that although the “Origin” has been close on thirty years before the world, the strangest misconceptions of the essential nature of the theory therein advocated are still put forth by serious writers.’[358] Critics less friendly to Darwin than Huxley have spoken still more strongly. I feel that Huxley’s judgment is too severe. It is true that Darwin had not the admirable gift of logical, lucid exposition which made Huxley himself one of the most luminous of scientific writers. But even when Darwin’s reasoning is most complex and difficult, there is a notable quality of sincerity and single-mindedness, which wins and retains your confidence. He seems somehow to have an exceptional power of taking you into his mental processes, and to make you think and see and feel as he does. If you feel that he may be wrong, it is because he feels that he may be wrong himself.
