"Your question what would convince me of design is a poser. If I saw an angel come down to teach us good, and I was convinced from others seeing him that I was not mad, I should believe in design. If I could be convinced thoroughly that life and mind was in an unknown way a function of other imponderable force, I should be convinced. If man was made of brass or iron and no way connected with any other organism which had ever lived, I should perhaps be convinced. But this is childish writing.
"I have lately been corresponding with Lyell, who, I think, adopts your idea of the stream of variation having been led or designed. I have asked him (and he says he will hereafter reflect and answer me) whether he believes that the shape of my nose was designed. If he does I have nothing more to say. If not, seeing what Fanciers have done by selecting individual differences in the nasal bones of pigeons, I must think that it is illogical to suppose that the variations, which natural selection preserves for the good of any being, have been designed. But I know that I am in the same sort of muddle (as I have said before) as all the world seems to be in with respect to free will, yet with everything supposed to have been foreseen or preordained."
The shape of his nose would perhaps not have been used as an illustration, if he had remembered Fitz-Roy's objection to that feature (see Autobiography, p. 26). He should, too, have remembered the difficulty of predicting the value to an organism of an apparently unimportant character.
In England Professor Huxley was at work in the evolutionary cause. He gave, in 1862, two lectures at Edinburgh on Man's Place in Nature. My father wrote:—
"I am heartily glad of your success in the North. By Jove, you have attacked Bigotry in its stronghold. I thought you would have been mobbed. I am so glad that you will publish your Lectures. You seem to have kept a due medium between extreme boldness and caution. I am heartily glad that all went off so well."
A review,[225] by F. W. Hutton, afterwards Professor of Biology and Geology at Canterbury, N. Z., gave a hopeful note of the time not far off when a broader view of the argument for Evolution would be accepted. My father wrote to the author[226]:—
Down, April 20th, 1861.
Dear Sir,—I hope that you will permit me to thank you for sending me a copy of your paper in the Geologist, and at the same time to express my opinion that you have done the subject a real service by the highly original, striking, and condensed manner with which you have put the case. I am actually weary of telling people that I do not pretend to adduce direct evidence of one species changing into another, but that I believe that this view in the main is correct, because so many phenomena can be thus grouped together and explained.
But it is generally of no use, I cannot make persons see this. I generally throw in their teeth the universally admitted theory of the undulations of light—neither the undulations, nor the very existence of ether being proved—yet admitted because the view explains so much. You are one of the very few who have seen this, and have now put it most forcibly and clearly. I am much pleased to see how carefully you have read my book, and what is far more important, reflected on so many points with an independent spirit. As I am deeply interested in the subject (and I hope not exclusively under a personal point of view) I could not resist venturing to thank you for the right good service which you have done. Pray believe me, dear sir,
Yours faithfully and obliged.
