“Which occurred” is obviously “which happened to occur, by some chance or accident entirely unconnected with use and disuse;” and though the word “accidental” is never used, there can be no doubt about Mr. Wallace’s desire to make the reader catch the fact that with him accident, and not, as with Erasmus Darwin and Lamarck, sustained effort, is the main purveyor of the variations whose accumulation amounts ultimately to specific difference. It is a pity, however, that instead of contenting himself like a theologian with saying that his opponent had been refuted over and over again, he did not refer to any particular and tolerably successful attempt to refute the theory that modifications in organic structure are mainly functional. I am fairly well acquainted with the literature of evolution, and have never met with any such attempt. But let this pass; as with Mr. Darwin, so with Mr. Wallace, and so indeed with all who accept Mr. Charles Darwin’s natural selection as the main means of modification, the central idea is luck, while the central idea of the Erasmus-Darwinian system is cunning.
I have given the opinions of these contending parties in their extreme development; but they both admit abatements which bring them somewhat nearer to one another. Design, as even its most strenuous upholders will admit, is a difficult word to deal with; it is, like all our ideas, substantial enough until we try to grasp it—and then, like all our ideas, it mockingly eludes us; it is like life or death—a rope of many strands; there is design within design, and design within undesign; there is undesign within design (as when a man shuffles cards designing that there shall be no design in their arrangement), and undesign within undesign; when we speak of cunning or design in connection with organism we do not mean cunning, all cunning, and nothing but cunning, so that there shall be no place for luck; we do not mean that conscious attention and forethought shall have been bestowed upon the minutest details of action, and nothing been left to work itself out departmentally according to precedent, or as it otherwise best may according to the chapter of accidents.
So, again, when Mr. Darwin and his followers deny design and effort to have been the main purveyors of the variations whose accumulation results in specific difference, they do not entirely exclude the action of use and disuse—and this at once opens the door for cunning; nevertheless, according to Erasmus Darwin and Lamarck, the human eye and the long neck of the giraffe are alike due to the accumulation of variations that are mainly functional, and hence practical; according to Charles Darwin they are alike due to the accumulation of variations that are accidental, fortuitous, spontaneous, that is to say, mainly cannot be reduced to any known general principle. According to Charles Darwin “the preservation of favoured,” or lucky, “races” is by far the most important means of modification; according to Erasmus Darwin effort non sibi res sed se rebus subjungere is unquestionably the most potent means; roughly, therefore, there is no better or fairer way of putting the matter, than to say that Charles Darwin is the apostle of luck, and his grandfather, and Lamarck, of cunning.
It should be observed also that the distinction between the organism and its surroundings—on which both systems are founded—is one that cannot be so universally drawn as we find it convenient to allege. There is a debatable ground of considerable extent on which res and me, ego and non ego, luck and cunning, necessity and freewill, meet and pass into one another as night and day, or life and death. No one can draw a sharp line between ego and non ego, nor indeed any sharp line between any classes of phenomena. Every part of the ego is non ego quâ organ or tool in use, and much of the non ego runs up into the ego and is inseparably united with it; still there is enough that it is obviously most convenient to call ego, and enough that it is no less obviously most convenient to call non ego, as there is enough obvious day and obvious night, or obvious luck and obvious cunning, to make us think it advisable to keep separate accounts for each.
I will say more on this head in a following chapter; in this present one my business should be confined to pointing out as clearly and succinctly as I can the issue between the two great main contending opinions concerning organic development that obtain among those who accept the theory of descent at all; nor do I believe that this can be done more effectually and accurately than by saying, as above, that Mr. Charles Darwin (whose name, by the way, was “Charles Robert,” and not, as would appear from the title-pages of his books, “Charles” only), Mr. A. R. Wallace, and their supporters are the apostles of luck, while Erasmus Darwin and Lamarck, followed, more or less timidly, by the Geoffroys and by Mr. Herbert Spencer, and very timidly indeed by the Duke of Argyll, preach cunning as the most important means of organic modification.
Note.—It appears from “Samuel Butler: A Memoir” (II, 29) that Butler wrote to his father (Dec. 1885) about a passage in Horace (near the beginning of the First Epistle of the First Book)—
Nunc in Aristippi furtim praecepta relabor,
Et mihi res, non me rebus subjungere conor.
On the preceding page he is adapting the second of these two verses to his own purposes.—H. F. J.

(Intercalated)
Mr. Spencer’s “The Factors of Organic Evolution”
Since the foregoing and several of the succeeding chapters were written, Mr. Herbert Spencer has made his position at once more clear and more widely understood by his articles “The Factors of Organic Evolution” which appeared in the Nineteenth Century for April and May, 1886. The present appears the fittest place in which to intercalate remarks concerning them.
