The Great Law of Love—the abstaining from that which we do not like when done to ourselves—Reciprocity—is the only relation to exist among associated… - J. Howard Moore

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.

I have just finished your little book on 'The Logic of Vegetarianism.' It is the best thing on this subject in existence – bold, brilliant, unanswerable. I am glad you are on earth. If it were not for a very few souls like you, this world would seem to me an intellectual solitude.

The well being of others is on an average as important as our own, and should as a general thing be appraised at the same value. If a certain amount of happiness is scheduled to fall to the lot of the earth, it makes absolutely no difference whether it falls on me, or on you, or on somebody a thousand miles away. It would serve the ends of absolute ethics quite as well if it fell on an insect or a horse as if it fell on a man. The only important thing from the standpoint of universal good is that the pleasure be experienced. It is not important what particular individual or species is the beneficiary. It might even go to another world, and be just as satisfactory to a universal well-wisher, who looked at Cosmos from the serene altitudes of pure reason, without any prejudices whatever one way or another in the matter. This is the ideal. It is a long, long way from our natures. But only in so far as we approximate this ideal do we rise above those imperfections of our being which have been ground out by the methods that have operated in the development of life on earth.
