These general criticisms have resolved themselves mainly into two.

Firstly, it is said that I ought not to write about biology on the ground of my past career, which my critics declare to have been purely literary. I wish I might indulge a reasonable hope of one day becoming a literary man; the expression is not a good one, but there is no other in such common use, and this must excuse it; if a man can be properly called literary, he must have acquired the habit of reading accurately, thinking attentively, and expressing himself clearly. He must have endeavoured in all sorts of ways to enlarge the range of his sympathies so as to be able to put himself easily en rapport with those whom he is studying, and those whom he is addressing. If he cannot speak with tongues himself, he is the interpreter of those who can—without whom they might as well be silent. I wish I could see more signs of literary culture among my scientific opponents; I should find their books much more easy and agreeable reading if I could; and then they tell me to satirise the follies and abuses of the age, just as if it was not this that I was doing in writing about themselves.

What, I wonder, would they say if I were to declare that they ought not to write books at all, on the ground that their past career has been too purely scientific to entitle them to a hearing? They would reply with justice that I should not bring vague general condemnations, but should quote examples of their bad writing. I imagine that I have done this more than once as regards a good many of them, and I dare say I may do it again in the course of this book; but though I must own to thinking that the greater number of our scientific men write abominably, I should not bring this against them if I believed them to be doing their best to help us; many such men we happily have, and doubtless always shall have, but they are not those who push to the fore, and it is these last who are most angry with me for writing on the subjects I have chosen. They constantly tell me that I am not a man of science; no one knows this better than I do, and I am quite used to being told it, but I am not used to being confronted with the mistakes that I have made in matters of fact, and trust that this experience is one which I may continue to spare no pains in trying to avoid.

Nevertheless I again freely grant that I am not a man of science. I have never said I was. I was educated for the Church. I was once inside the Linnean Society’s rooms, but have no present wish to go there again; though not a man of science, however, I have never affected indifference to the facts and arguments which men of science have made it their business to lay before us; on the contrary, I have given the greater part of my time to their consideration for several years past. I should not, however, say this unless led to do so by regard to the interests of theories which I believe to be as nearly important as any theories can be which do not directly involve money or bodily convenience.

The second complaint against me is to the effect that I have made no original experiments, but have taken all my facts at second hand. This is true, but I do not see what it has to do with the question. If the facts are sound, how can it matter whether A or B collected them? If Professor Huxley, for example, has made a series of valuable original observations (not that I know of his having done so), why am I to make them over again? What are fact-collectors worth if the fact co-ordinators may not rely upon them? It seems to me that no one need do more than go to the best sources for his facts, and tell his readers where he got them. If I had had occasion for more facts I daresay I should have taken the necessary steps to get hold of them, but there was no difficulty on this score; every text-book supplied me with all, and more than all, I wanted; my complaint was that the facts which Mr. Darwin supplied would not bear the construction he tried to put upon them; I tried, therefore, to make them bear another which seemed at once more sound and more commodious; rightly or wrongly I set up as a builder, not as a burner of bricks, and the complaint so often brought against me of not having made experiments is about as reasonable as complaint against an architect on the score of his not having quarried with his own hands a single one of the stones which he has used in building. Let my opponents show that the facts which they and I use in common are unsound, or that I have misapplied them, and I will gladly learn my mistake, but this has hardly, to my knowledge, been attempted. To me it seems that the chief difference between myself and some of my opponents lies in this, that I take my facts from them with acknowledgment, and they take their theories from me—without.

One word more and I have done. I should like to say that I do not return to the connection between memory and heredity under the impression that I shall do myself much good by doing so. My own share in the matter was very small. The theory that heredity is only a mode of memory is not mine, but Professor Hering’s. He wrote in 1870, and I not till 1877. I should be only too glad if he would take his theory and follow it up himself; assuredly he could do so much better than I can; but with the exception of his one not lengthy address published some fifteen or sixteen years ago he has said nothing upon the subject, so far at least as I have been able to ascertain; I tried hard to draw him in 1880, but could get nothing out of him. If, again, any of our more influential writers, not a few of whom evidently think on this matter much as I do, would eschew ambiguities and tell us what they mean in plain language, I would let the matter rest in their abler hands, but of this there does not seem much chance at present.

I wish there was, for in spite of the interest I have felt in working the theory out and the information I have been able to collect while doing so, I must confess that I have found it somewhat of a white elephant. It has got me into the hottest of hot water, made a literary Ishmael of me, lost me friends whom I have been sorry to lose, cost me a good deal of money, done everything to me, in fact, which a good theory ought not to do. Still, as it seems to have taken up with me, and no one else is inclined to treat it fairly, I shall continue to report its developments from time to time as long as life and health are spared me. Moreover, Ishmaels are not without their uses, and they are not a drug in the market just now.

I may now go on to Mr. Spencer.

Chapter II
Mr. Herbert Spencer

Mr. Herbert Spencer wrote to the Athenæum (April 5, 1884), and quoted certain passages from the 1855 edition of his “Principles of Psychology,” “the meanings and implications” from which he contended were sufficiently clear. The passages he quoted were as follows:—
