"I am a vegetarian because I believe that present-day ethics is founded on that puerile, pre-Darwinian delusion that all other kinds of creatures and all worlds were created explicitly for the hominine species. Vegetarianism is the ethical corollary of evolution. It is simply the expansion of ethics to suit the biological revelations of Charles Darwin. Evolution has taught us the kinship of all creatures."

“The human beings who possess the dominion of land and machinery and compel others, in order to obtain the essentials of existence, to serve them, are as truly masters of slaves as they who exact blood from the dorsals of their fellows with literal slave whips.”

“It is not possible, and it never will be possible, to organize all the beings occupying space into one immense confederacy. This would be ideal, but from the inexorable nature of things it can never be. The denizens of the sea depths can not correlate with the inhabitants of the clouds. The lion can not fraternize with the lamb, nor the hawk with the sparrow. The natures of beings have been evolved thru war, and they are in large part irredeemably antagonistic. But the approximation, if honest, may be more successful than is supposed, and may include many species not human. The bird may contribute his song and plumage, the sheep his fleece, the horse, the ox, the elephant, and the camel their strength or speed, the cow and the fowl their secretions, the dog his fidelity, and man his art. The ultimate and ideal aggregation of the living universe will not be a pan-American union nor a Euro-American league, nor even an aggregation whose spirit is embodied in a parliament of man, but the widest and most consummate possible Confederation of the Consciousnesses.”

“Act toward others as you would act toward a part of your own self is, it seems to me, the plainest and truest and the most comprehensive and useful rule of conduct ever formulated on this earth. It is the expression of balanced egoism and altruism. It is the soul of sympathy and oneness. It may be called the Law of the Larger Self. It is the extension of the regard which we have for ourselves to those below, above, and around us. It is simply the law of the individual organism widened to apply to the Sentient Organism. It is the message which is destined in time to come to redeem this world from the primal curse of selfishness. It is the dream which has been dreamed by the great teachers of the past independently of each other, merely by observing the actions of men and thinking what rule if followed would cure the wrongs and sufferings of this world.”

“Let us be true to our ideals, true to the spirit of Universal Compassion—whether we walk with the lone worm wandering in the twilight of consciousness, the feathered forms of the fields and forests, the kine of the meadows, the simple savage on the banks of the gladed river, the political blanks whom men call wives, or the outcasts of human industry.”

“Much of the vagueness of the human mind is due to the fact that the mind is largely composed of material derived second-hand from books. The ideas are not read.”

“Let us be alive. Let us be liquid. Let us be Young. The Old atrophy, because they cease to flow. Let us be loyal for ever to those heavenly banners that flutter everywhere in the airs of this age—the banners of those who strive for a Better World.”
