The accusation was a very grave one; it was made in a very public place. I gave my name; I adduced the strongest _primâ facie_ grounds for the acceptance of my statements; but there was no rejoinder, and for the best of all reasons—that no rejoinder was possible. Besides, what is the good of having a reputation for candour if one may not stand upon it at a pinch? I never yet knew a person with an especial reputation for candour without finding sooner or later that he had developed it as animals develop their organs, through “sense of need.” Not only did Mr. Darwin remain perfectly quiet, but all reviewers and _littérateurs_ remained perfectly quiet also. It seemed—though I do not for a moment believe that this is so—as if public opinion rather approved of what Mr. Darwin had done, and of his silence than otherwise. I saw the “Life of Erasmus Darwin” more frequently and more prominently advertised now than I had seen it hitherto—perhaps in the hope of selling off the adulterated copies, and being able to reprint the work with a corrected title page. Presently I saw Professor Huxley hastening to the rescue with his lecture on the coming of age of the “Origin of Species,” and by May it was easy for Professor Ray Lankester to imply that Mr. Darwin was the greatest of living men. I have since noticed two or three other controversies raging in the _Athenæum_ and _Times_; in each of these cases I saw it assumed that the defeated party, when proved to have publicly misrepresented his adversary, should do his best to correct in public the injury which he had publicly inflicted, but I noticed that in none of them had the beaten side any especial reputation for candour. This probably made all the difference. But however this may be, Mr. Darwin left me in possession of the field, in the hope, doubtless, that the matter would blow over—which it apparently soon did. Whether it has done so in reality or no, is a matter which remains to be seen. My own belief is that people paid no attention to what I said, as believing it simply incredible, and that when they come to know that it is true, they will think as I do concerning it. From ladies and gentlemen of science I admit that I have no expectations. There is no conduct so dishonourable that people will not deny it or explain it away, if it has been committed by one whom they recognise as of their own persuasion. It must be remembered that facts cannot be respected by the scientist in the same way as by other people. It is his business to familiarise himself with facts, and, as we all know, the path from familiarity to contempt is an easy one.
