If then, “the most fundamental principle” of mind is memory, it follows that memory enters also as a fundamental principle into development of body. For mind and body are so closely connected that nothing can enter largely into the one without correspondingly affecting the other.
On a later page, indeed, Mr. Romanes speaks point-blank of the new-born child as “embodying the results of a great mass of hereditary experience” (p. 77), so that what he is driving at can be collected by those who take trouble, but is not seen until we call up from our own knowledge matter whose relevancy does not appear on the face of it, and until we connect passages many pages asunder, the first of which may easily be forgotten before we reach the second. There can be no doubt, however, that Mr. Romanes does in reality,
like Professor Hering and myself, regard development, whether of mind or body, as due to memory, for it is nonsense indeed to talk about “hereditary experience” or “hereditary memory” if anything else is intended.
I have said above that on page 113 of his recent work Mr. Romanes declares the analogies between the memory with which we are familiar in daily life, and hereditary memory, to be “so numerous and precise” as to justify us in considering them as of one and the same kind.
This is certainly his meaning, but, with the exception of the words within inverted commas, it is not his language. His own words are these:—
“Profound, however, as our ignorance unquestionably is concerning the physical substratum of memory, I think we are at least justified in regarding this substratum as the same both in ganglionic or organic, and in conscious or psychological memory, seeing that the analogies between them are so numerous and precise. Consciousness is but an adjunct which arises when the physical processes, owing to infrequency of repetition, complexity of operation, or other causes, involve what I have before called ganglionic friction.”
I submit that I have correctly translated Mr. Romanes’ meaning, and also that we have a right to complain of his not saying what he has to say in words which will involve less “ganglionic friction” on the part of the reader.
Another example may be found on p. 43 of Mr. Romanes’ book. “Lastly,” he writes, “just as innumerable special mechanisms of muscular co-ordinations are found to be inherited, innumerable special associations of ideas are found to be the same, and in one
case as in the other the strength of the organically imposed connection is found to bear a direct proportion to the frequency with which in the history of the species it has occurred.”
Mr. Romanes is here intending what the reader will find insisted on on p. 98 of the present volume; but how difficult he has made what could have been said intelligibly enough, if there had been nothing but the reader’s comfort to be considered. Unfortunately that seems to have been by no means the only thing of which Mr. Romanes was thinking, or why, after implying and even saying over and over again that instinct is inherited habit due to inherited memory, should he turn sharply round on p. 297 and praise Mr. Darwin for trying to snuff out “the well-known doctrine of inherited habit as advanced by Lamarck”? The answer is not far to seek. It is because Mr. Romanes did not merely want to tell us all about instinct, but wanted also, if I may use a homely metaphor, to hunt with the hounds and run with the hare at one and the same time.
