On reflection, however, I was again met with the overwhelming weight of the evidence in favour of structure and habit being mainly due to memory. I accordingly gathered as much as I could second-hand of what Lamarck had said, reserving a study of his “Philosophie Zoologique” for another occasion, and read as much about ants and bees as I could find in readily accessible works. In a few days I saw my way again; and now, reading the “Origin of Species” more closely, and I may say more sceptically, the antagonism between Mr. Darwin and Lamarck became fully apparent to me, and I saw how incoherent and unworkable in practice the later view was in comparison with the earlier. Then I read Mr. Darwin’s answers to miscellaneous objections, and was met, and this time brought up, by the passage beginning “In the earlier editions of this work,” {24a} &c., on which I wrote very severely in “Life and Habit”; {24b} for I felt by this time that the difference of opinion between us was radical, and that the matter must be fought out according to the rules of the game. After this I went through the earlier part of my book, and cut out the expressions which I had used inadvertently, and which were inconsistent with a teleological view. This necessitated only verbal alterations; for, though I had not known it, the spirit of the book was throughout teleological. I now saw that I had got my hands full, and abandoned my intention of touching upon “Pangenesis.” I took up the words of Mr. Darwin quoted above, to the effect that it would be a serious error to ascribe the greater number of instincts to transmitted habit. I wrote chapter xi. of “Life and Habit,” which is headed “Instincts as Inherited Memory”; I also wrote the four subsequent chapters, “Instincts of Neuter Insects,” “Lamarck and Mr. Darwin,” “Mr. Mivart and Mr. Darwin,” and the concluding chapter, all of them in the month of October and the early part of November 1877, the complete book leaving the binder’s hands December 4, 1877, but, according to trade custom, being dated 1878. It will be seen that these five concluding chapters were rapidly written, and this may account in part for the directness with which I said anything I had to say about Mr. Darwin; partly this, and partly I felt I was in for a penny and might as well be in for a pound. I therefore wrote about Mr. Darwin’s work exactly as I should about any one else’s, bearing in mind the inestimable services he had undoubtedly—and must always be counted to have—rendered to evolution.
