In a book published a few weeks before Mr. Spencer’s letter appeared { 29a} I had said that though Mr. Spencer at times closely approached Professor Hering and “Life and Habit,” he had nevertheless nowhere shown that he considered memory and heredity to be parts of the same story and parcel of one another. In his letter to the _Athenæum_, indeed, he does not profess to have upheld this view, except “by implications;” nor yet, though in the course of the six or seven years that had elapsed since “Life and Habit” was published I had brought out more than one book to support my earlier one, had he said anything during those years to lead me to suppose that I was trespassing upon ground already taken by himself. Nor, again, had he said anything which enabled me to appeal to his authority—which I should have been only too glad to do; at last, however, he wrote, as I have said, to the _Athenæum_ a letter which, indeed, made no express claim, and nowhere mentioned myself, but “the meanings and implications” from which were this time as clear as could be desired, and amount to an order to Professor Hering and myself to stand aside.
The question is, whether the passages quoted by Mr. Spencer, or any others that can be found in his works, show that he regarded heredity in all its manifestations as a mode of memory. I submit that this conception is not derivable from Mr. Spencer’s writings, and that even the passages in which he approaches it most closely are unintelligible till read by the light of Professor Hering’s address and of “Life and Habit.”
True, Mr. Spencer made abundant use of such expressions as “the experience of the race,” “accumulated experiences,” and others like them, but he did not explain—and it was here the difficulty lay—how a race could have any experience at all. We know what we mean when we say that an individual has had experience; we mean that he is the same person now (in the common use of the words), on the occasion of some present action, as the one who performed a like action at some past time or times, and that he remembers how he acted before, so as to be able to turn his past action to account, gaining in proficiency through practice. Continued personality and memory are the elements that constitute experience; where these are present there may, and commonly will, be experience; where they are absent the word “experience” cannot properly be used.
