It ought to be perfectly clear by this time that the popularity and unpopularity of propositions in no way coincide with their truth and falsity. It … - J. Howard Moore

The relations of living beings to each other observed among the races (especially the unconscious races) of the earth to-day, or as contemplated in the paleontologies of past evolutions, are not such, I assert, as to appeal with anything like eloquence to the ideal of any unbiased mind. I will assert further, that the principle that has operated in the development of life on this planet, the natural selection principle, and the relations prevalently established among living beings by the necessities of this principle, are irrational and barbarous—that the moral progress thus far made by civilized beings here on the earth has been made in spite of, and in opposition to, this principle—and finally, that the great task of reforming and regenerating the universe and of establishing right relations among its inhabitants consists in the elimination of those tendencies implanted in the natures of living beings by the struggle and survival principle.

The chief activities of beings, both human and non-human, are put forth, directly or indirectly, for the purpose of procuring food. The suppression, entire or partial, of one being by another for nutritive purposes is, therefore, the form of the most frequent and excessive egoism. The lowly forms of life—the worms, echinoderms, mollusks, and the like—are, for the most part, vegetarians. So, also, are prevalently the insects, birds, rodents, and ungulates. These creatures are not, as a rule, aggressively harmful to each other, chiefly indifferent. But upon these inoffensive races feed with remorseless maw the reptilia, the insectivora, and the carnivora. These being-eaters cause to the earth-world its bloodiest experiences. It is their nature (established organically by long selection, or, as in the case of man, acquired tentatively) to subsist, not on the kingdom of the plant, the natural and primal storehouse of animal energy, but on the skeletons and sensibilities of their neighbors and friends. The serpent dines on the sparrow and the sparrow ingulfs the gnat; the tiger slays the jungle-fowl and the coyote plunders the lamb; the seal subsists on fish and the ursus maritimus subsists on seal; the ant enslaves the aphidae and man eats and enslaves what can not get away from him. Life riots on life—tooth and talon, beak and paw. It is a sickening contemplation, but life everywhere, in its aspect of activity, is largely made up of the struggle by one being against another for existence—of the effort by one being to circumvent, subjugate, or destroy another, and of the counter effort to reciprocate or escape.

Wherever Buddhism prevails, there will be found in greater or less purity, as one of the cardinal principles of its founder, the doctrine of the sacredness of all Sentient Life.
