[Footnote 21: P.F. 297. "The truth is that morals are built on a far surer foundation than that of creeds, which are here to-day and gone to-morrow. They are built on the solid rock of experiences, and of the 'survival of the fittest,' which in the long evolution of the human race from primeval savages, have by 'natural selection' and 'heredity' become almost instinctive." (How careless is this terminology. In the previous page he denies morality to be a matter of hereditary instinct.)]
