With most cordial thanks and respect, believe me, my dear Carpenter, yours very sincerely, CH. DARWIN. CHARLES DARWIN TO L. JENYNS. (Rev. L. Blomefield.) Down, January 7th, 1860. My dear Jenyns, I am very much obliged for your letter. It is of great use and interest to me to know what impression my book produces on philosophical and instructed minds. I thank you for the kind things which you say; and you go with me much further than I expected. You will think it presumptuous, but I am convinced, IF CIRCUMSTANCES LEAD YOU TO KEEP THE SUBJECT IN MIND, that you will go further. No one has yet cast doubts on my explanation of the subordination of group to group, on homologies, embryology, and rudimentary organs; and if my explanation of these classes of facts be at all right, whole classes of organic beings must be included in one line of descent. The imperfection of the Geological Record is one of the greatest difficulties... During the earliest period the record would be most imperfect, and this seems to me sufficient to account for our not finding intermediate forms between the classes in the same great kingdoms. It was certainly rash in me putting in my belief of the probability of all beings having descended from ONE primordial form; but as this seems yet to me probable, I am not willing to strike it out. Huxley alone supports me in this, and something could be said in its favour. With respect to man, I am very far from wishing to obtrude my belief; but I thought it dishonest to quite conceal my opinion. Of course it is open to every one to believe that man appeared by a separate miracle, though I do not myself see the necessity or probability. Pray accept my sincere thanks for your kind note. Your going some way with me gives me great confidence that I am not very wrong. For a very long time I halted half way; but I do not believe that any enquiring mind will rest half-way. People will have to reject all or admit all; by ALL I mean only the members of each great kingdom. My dear Jenyns, yours most sincerely, C. DARWIN. CHARLES DARWIN TO C. LYELL.
