I cannot say that I agree with Hooker about the public not liking to be told what to conclude, IF COMING FROM ONE IN YOUR POSITION. But I am heartily sorry that I was led to make complaints, or something very like complaints, on the manner in which you have treated the subject, and still more so anything about myself. I steadily ENDEAVOUR never to forget my firm belief that no one can at all judge about his own work. As for Lamarck, as you have such a man as Grove with you, you are triumphant; not that I can alter my opinion that to me it was an absolutely useless book. Perhaps this was owing to my always searching books for facts, perhaps from knowing my grandfather's earlier and identically the same speculation. I will only further say that if I can analyse my own feelings (a very doubtful process), it is nearly as much for your sake as for my own, that I so much wish that your state of belief could have permitted you to say boldly and distinctly out that species were not separately created. I have generally told you the progress of opinion, as I have heard it, on the species question. A first-rate German naturalist (No doubt Haeckel, whose monograph on the Radiolaria was published in 1862. In the same year Professor W. Preyer of Jena published a dissertation on Alca impennis, which was one of the earliest pieces of special work on the basis of the 'Origin of Species.') (I now forget the name!), who has lately published a grand folio, has spoken out to the utmost extent on the 'Origin.' De Candolle, in a very good paper on "Oaks," goes, in Asa Gray's opinion, as far as he himself does; but De Candolle, in writing to me, says WE, "we think this and that;" so that I infer he really goes to the full extent with me, and tells me of a French good botanical palaeontologist (name forgotten) (The Marquis de Saporta.), who writes to De Candolle that he is sure that my views will ultimately prevail. But I did not intend to have written all this. It satisfies me with the final results, but this result, I begin to see, will take two or three lifetimes. The entomologists are enough to keep the subject back for half a century. I really pity your having to balance the claims of so many eager aspirants for notice; it is clearly impossible to satisfy all... Certainly I was struck with the full and due honour you conferred on Falconer. I have just had a note from Hooker... I am heartily glad that you have made him so conspicuous; he is so honest, so candid, and so modest... I have read --. I could find nothing to lay hold of, which in one sense I am very glad of, as I should hate a controversy; but in another sense I am very sorry for, as I long to be in the same boat with all my friends... I am heartily glad the book is going off so well. Ever yours, C. DARWIN. CHARLES DARWIN TO J.D. HOOKER. Down [March 29, 1863].
