Note 20 — Chapter VI

I owe my first clear apprehension of the gradual evolution of the preservative and altruistic elements in nature, arising from the struggle for existence, to a sermon of Dr. Abbott's called The Manifestation of the Son of God, now, I fear, out of print. Of course Darwin recognized these factors as a necessary complement to the survival of the fittest, else had there been no fittest to survive; but the exigencies of proving his theory of the origin of species necessitated his dwelling on the destructive and weeding-out elements of Nature—"Nature red in tooth and claw," rather than the equally pervasive Nature of the brooding wing and the flowing breast. Had not Professor Drummond unfortunately mixed it up with a good deal of extraneous sentiment, his main thesis would scarcely have been impugned.
