And, after all, the humane spirit, which is the motive power of all true schemes of reform, is, by its very essence, independent of belief in what is… - Henry Stephens Salt

I say ethical principle, because it is beyond doubt that the chief motive of Vegetarianism is the humane one. Questions of hygiene and of economy both play their part, and an important part, in a full discussion of food reform; but the feeling which underlies and animates the whole movement is the instinctive horror of butchery, especially the butchery of the more highly organized animals, so human, so near akin to man.

[The] notion of the life of an animal having 'no moral purpose,' belongs to a class of ideas which cannot possibly be accepted by the advanced humanitarian thought of the present day—it is a purely arbitrary assumption, at variance with our best instincts, at variance with our best science, and absolutely fatal (if the subject be clearly thought out) to any full realization of animals' rights. If we are ever going to do justice to the lower races, we must get rid of the antiquated notion of a 'great gulf' fixed between them and mankind, and must recognize the common bond of humanity that unites all living beings in one universal brotherhood.

If "rights" exist at all—and both feeling and usage indubitably prove that they do exist—they cannot be consistently awarded to men and denied to animals, since the same sense of justice and compassion apply in both cases.
