This was the only one of the original forty-five my’s that was cut out before the appearance of the fifth edition in 1869, and its excision throws curious light upon the working of Mr. Darwin’s mind. The selection of the most categorical my out of the whole forty-five, shows that Mr. Darwin knew all about his my’s, and, while seeing reason to remove this, held that the others might very well stand. He even left “On my _view_ of descent with modification,” {203a} which, though more capable of explanation than “my theory,” &c., still runs it close; nevertheless the excision of even a single my that had been allowed to stand through such close revision as those to which the “Origin of Species” had been subjected betrays uneasiness of mind, for it is impossible that even Mr. Darwin should not have known that though the my excised in 1866 was the most technically categorical, the others were in reality just as guilty, though no tower of Siloam in the shape of excision fell upon them. If, then, Mr. Darwin was so uncomfortable about this one as to cut it out, it is probable he was far from comfortable about the others. This view derives confirmation from the fact that in 1869, with the fifth edition of the “Origin of Species,” there was a stampede of my’s throughout the whole work, no less than thirty out of the original forty-five being changed into “the,” “our,” “this,” or some other word, which, though having all the effect of my, still did not say “my” outright. These my’s were, if I may say so, sneaked out; nothing was said to explain their removal to the reader or call attention to it. Why, it may be asked, having been considered during the revisions of 1861 and 1866, and with only one exception allowed to stand, why should they be smitten with a homing instinct in such large numbers with the fifth edition? It cannot be maintained that Mr. Darwin had had his attention called now for the first time to the fact that he had used my perhaps a little too freely, and had better be more sparing of it for the future. The my excised in 1866 shows that Mr. Darwin had already considered this question, and saw no reason to remove any but the one that left him no loophole. Why, then, should that which was considered and approved in 1859, 1861, and 1866 (not to mention the second edition of 1859 or 1860) be retreated from with every appearance of panic in 1869? Mr. Darwin could not well have cut out more than he did—not at any rate without saying something about it, and it would not be easy to know exactly what say. Of the fourteen my’s that were left in 1869, five more were cut out in 1872, and nine only were allowed eventually to remain. We naturally ask, Why leave any if thirty-six ought to be cut out, or why cut out thirty-six if nine ought to be left—especially when the claim remains practically just the same after the excision as before it?
