“The classical argument for why a supposedly decent and moral creature like Homo sapiens can mistreat and even extirpate other species rests upon an extreme position in a continuum. The Cartesian tradition, formulated explicitly in the seventeenth century, but developed in "folk" and other versions throughout human history no doubt, holds that other animals are little more than unfeeling machines, with only humans enjoying "consciousness," however defined.”

“I don't hold animals superior or even equal to humans. The whole case for behaving decently to animals rests on the fact that we are the superior species. We are the species uniquely capable of imagination, rationality and moral choice—and that is precisely why we are under the obligation to recognise and respect the rights of animals.”

“Throughout the history of our ascent to dominance as the master species, our victimization of animals has served as the model and foundation for our victimization of each other. The study of human history reveals the pattern: first, humans exploit and slaughter animals; then, they treat other people like animals and do the same to them.”

“The idea that consciousness is a mystery is a prejudice inherited from monotheism. The early seventeenth-century French philosopher René Descartes believed that animals other than humans are insensate machines. Obviously, this was a restatement in rationalist terms of the Christian belief that only humans have souls. Even if mind and matter were categorically distinct, that would not mean humans alone have minds. It was reported that in order to test his theories, Descartes used to throw animals out of the window and observe their reactions. Looking at behaviour of this kind, one might reasonably conclude that humans are the senseless machines.”

“We are indeed human beings. We are merely not Homo sapiens. Homo sapiens is a species, something into which one is born. Humanity one chooses. Men who choose inhumanity are merely upright beasts.”

“While Homo sapiens may not be saintly, they're pretty decent. We have what we have. Most importantly, there's a great chance to nurture and create a new kind of human — Homo humanus, the Humane Human.”

“Humans: The only animal who can laugh!/ We can enjoy the lighter side of life/ And we can also laugh at others/ And ridicule others!”

“Who, or rather what, are Homo sapiens? The more accurate the knowledge about him, the clearer path for the further development of human society.”

“Neither in the ancient pagan world nor in any other culture has human history ever been thought to have an overarching significance. In Greece and Rome, it was a series of natural cycles of growth and decline. In India, it was a collective dream, endlessly repeated. The idea that history must make sense is just a Christian prejudice. If you believe that humans are animals, there can be no such thing as the history of humanity, only the lives of particular humans. If we speak of the history of the species at all, it is only to signify the unknowable sum of these lives. As with other animals, some lives are happy, others wretched. None has a meaning that lies beyond itsel£. Looking for meaning in history is like looking for patterns in clouds.”

“On the positive side, my anarchism came mainly as a corollary to the estimate of human capacity for self-improvement which I had picked up from Mr. Jefferson. His fundamental idea appeared to be that everyone answering to the zoological classification of homo sapiens is a human being, and therefore is indefinitely improvable. The essence of it is that homo sapiens in his natural state really wishes and means to be as decent towards his fellow-beings as he can, and under favorable conditions will progress in decency.”
