As long as there are slaughterhouses there will be battlefields. A vegetarian diet is the acid test of humanitarianism.

No member of the animal kingdom nurses past maturity, no member of the animal kingdom ever did a thing to me. Its why I don't eat red meat or white fish, don't give me no blue cheese. Were all members of the animal kingdom, leave your brothers and sisters in the sea.

For what purpose humanity is there should not even concern us: why you are here, that you should ask yourself: and if you have no ready answer, then set for yourself goals, high and noble goals, and perish in pursuit of them!

The sole meaning of life is to serve humanity.

Man lives consciously for himself, but is an unconscious instrument in the attainment of the historic, universal, aims of humanity.

The march of humanity, springing as it does from an infinite multitude of individual wills, is continuous.
