competitors for the supply (assumed to be limited) of subsistence available. We taught Prussia this religion; and Prussia bettered our instruction so effectively that we presently found ourselves confronted with the necessity of destroying Prussia to prevent Prussia destroying us. And that has just ended in each destroying the other to an extent doubtfully reparable in our time. It may be asked how so imbecile and dangerous a creed ever came to be accepted by intelligent beings. I will answer that question more fully in my next volume of plays, which will be entirely devoted to the subject. For the present I will only say that there were better reasons than the obvious one that such sham science as this opened a scientific career to very stupid men, and all the other careers to shameless rascals, provided they were industrious enough. It is true that this motive operated very powerfully; but when the new departure in scientific doctrine which is associated with the name of the great naturalist Charles Darwin began, it was not only a reaction against a barbarous pseudo-evangelical teleology intolerably obstructive to all scientific progress, but was accompanied, as it happened, by discoveries of extraordinary interest in physics, chemistry, and that lifeless method of evolution which its investigators called Natural Selection. Howbeit, there was only one result possible in the ethical sphere, and that was the banishment of conscience from human affairs, or, as Samuel Butler vehemently put it, "of mind from the universe."
