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.
