"Animals more obviously violate the concept of goodness, for none can live without tearing and devouring other organized beings, whether vegetables or other animals, or else sapping their strength as noxious parasites. The larger ambulatory animals can hardly move without crushing the herbage and multitudes of small creeping things; and all compete with each other for space and nourishment in the same manner as plants, but often far more violently. Moreover, they struggle for mates in a fashion wholly unknown among vegetables, even the milder herbivores sometimes exhibiting in their quarrels with rivals a fury that astounds us. Thus none is wholly good; yet those which devour only vegetation seem to be endowed by nature with a capacity for goodness lacking in those which kill and tear for food creatures more akin to themselves; while the fiercest kinds, which destroy living things that they do not require to sustain their own lives, fall most conspicuously short of goodness."

“The wild life of nature, regarded simply as woodland glades, murmuring brooks, fragrant flowers and songful birds, or the tranquil emptiness of a seascape in calm weather, is restful and refreshing after the clangor and turmoil of human existence, especially in the crowded centers of population. Its myriad shapes and colors divert the fevered mind from its too-absorbing problems. But viewed with a more penetrating and philosophic eye, what spectacle could be more hideously revolting than that of countless animals, each busily stuffing itself with as many other living things as its maw can hold? Were this all that we could detect beneath the seemingly tran-quil face of nature, some who now turn to it for spiritual comfort and refreshment might shrink away in horror.”

“Earth has no more distressing spectacle than that of a predator suddenly striking down some defenseless creature innocently singing or attending its young, no sight more pitifully repulsive than the hideously mangled remains of what, a few hours before, was a beautiful animal enjoying its life.”

“That evolution has accomplished much that is splendid and admirable, it would be ungrateful to deny. That the means it has employed have often been ruthlessly harsh is a proposition to which every compassionate person will attest.”

“After long pondering, I believe that I can define good and evil in terms to which even a biologist of the mechanical school can hardly take exception. At least, I fancy that I can do so for evil. The great evil of life is parasitism.”
