“Even if we ourselves are not personally scandalized by the notion of other animals as close relatives, even if our age has accommodated to the idea, the passionate resistance of so many of us, in so many epochs and cultures, and by so many distinguished scholars, must say something important about us. What can we learn about ourselves from an apparent error so widespread, propagated by so many leading philosophers and scientists, both ancient and modern, with such assurance and self-satisfaction?

One of several possible answers: A sharp distinction between humans and "animals" is essential if we are to bend them to our will, make them work for us, wear them, eat them--without any disquieting tinges of guilt or regret. With untroubled consciences, we can render whole species extinct--for our perceived short-term benefit, or even through simple carelessness. Their loss is of little import: Those beings, we tell ourselves, are not like us. An unbridgeable gap gas thus a practical role to play beyond the mere stroking of human egos. Darwin's formulation of this answer was: "Animals whom we have made our slaves, we do not like to consider our equals.”

“What would it mean for us to come to terms with the knowledge that civilization, our whole mode of development and culture, has been premised and built upon extermination—on a history experienced as "terror" without end" (to borrow a phrase from Adorno)? To dwell on such a thought would be to throw into almost unbearable relief the distance between our narratives of inherent human dignity and grace and moral superiority, on the one hand, and the most elemental facts of our actual social existence, on the other. We congratulate ourselves for our social progress—for democratic governance and state-protected civil and human rights (however notional or incompletely defended—yet continue to enslave and kill millions of sensitive creatures who in many biological, hence emotional and cognitive particulars resemble us. To truly meditate on such a contradiction is to comprehend our self-understanding to be not merely flawed, but comically delusional...

In the nineteenth century, the animal welfare advocate Edward Maitland warned that our destruction of other animals lead only to our own "debasement and degradation of character" as a species. "For the principles of Humanity cannot be renounced with impunity; but their renunciation, if persisted in, involves inevitably the forfeiture of humanity itself. And to cease through such forfeiture man is to become demon." What else indeed can we call a being but demon who routinely enslaves and kills thousands of millions of other gentle beings, imprisons them in laboratories, electrocutes or poisons or radiates or drowns them?”

“It's not that there are no differences between human and non-human animals, any more than there are no differences between black people and white people, freeborn citizens and slaves, men and women, Jews and gentiles, gays or heterosexuals. The question is rather: are they morally relevant differences? This matters because morally catastrophic consequences can ensue when we latch on to a real but morally irrelevant difference between sentient beings.”
― David Pearce

“The animals themselves are incapable of demanding their own liberation, or of protesting against their condition with votes, demonstrations, or bombs. Human beings have the power to continue to oppress other species forever, or until we make this planet unsuitable for living beings. Will our tyranny continue, proving that we really are the selfish tyrants that the most cynical of poets and philosophers have always said we are? Or will we rise to the challenge and prove our capacity for genuine altruism by ending our ruthless exploitation of the species in our power, not because we are forced to do so by rebels or terrorists, but because we recognize that our position is morally indefensible? The way in which we answer this question depends on the way in which each one of us, individually, answers it.”
