The psychology of the exploitation of nonhuman beings by human beings is not different in kind from the psychology of any other act of exploitation. … - J. Howard Moore

[T]he belief that the bodies of other beings take a necessary part in human alimentation is more than a tradition: it is a convenience.

The next hundred years will witness the greatest improvement in moral practice and understanding this world has ever seen. Nothing to compare with it has ever taken place in the evolution of ethics. The twentieth century is going to be a humanitarian century. The twenty-first century will dawn on a very different condition of things from that which we see around us to-day. Men are going to be Brothers, as certainly as the stars rise in the east. The marching and counter-marching going on in the industrial world to-day will end in a new order of society based on Mutualism, in which there will be not only division of labour but division of the products of labour as well. And along with the recognition of human brotherhood will come, is bound to come, the corollary recognition of the brotherhood of all those that feel.
