All are agreed that the various moral qualities are in a sense bestowed by nature: we are just, and capable of temperance, and brave, and possessed of the other virtues from the moment of our birth. But nevertheless we expect to find that true goodness is something different, and that the virtues in the true sense come to belong to us in another way. For even children and wild animals possess the natural dispositions, yet without Intelligence these may manifestly be harmful.
If chimpanzees have consciousness, if they are capable of abstractions, do they not have what until now has been described as 'human rights'? How smart does a chimp have to be before killing him constitutes murder?
If a group of beings from another planet were to land on Earth - beings who considered themselves as superior to you as you feel yourself to be to other animals - would you concede them the rights over you that you assume over other animals?
cruelty to animals is contrary to man's duty to himself, because it deadens in him the feeling of sympathy for their sufferings, and thus a natural tendency that is very useful to morality in relation to other human beings is weakened.
I felt the first inkling of a thing that presently grew quite clear in my mind, that oppressed me for many days, a sense of dethronement, a persuasion that I was no longer a master, but an animal among the animals, under the Martian heel.With us it would be as with them, to lurk and watch, to run and hide; the fear and empire of man had passed away.
A thing may be too sad to be believed or too wicked to be believed or too good to be believed; but it cannot be too absurd to be believed in this planet of frogs and elephants, of crocodiles and cuttle-fish.
Nor was civil society founded merely to preserve the lives of its members; but that they might live well: for otherwise a state might be composed of slaves, or the animal creation... nor is it an alliance mutually to defend each other from injuries, or for a commercial intercourse. But whosoever endeavors to establish wholesome laws in a state, attends to the virtues and vices of each individual who composes it; from whence it is evident, that the first care of him who would found a city, truly deserving that name, and not nominally so, must be to have his citizens virtuous.
Let's stick to the practical and the concrete: Would you like it if people lived in a virtual world? If machines were smarter than people? If, in the future, people, animals and plants were products of technology? If you don't like these ideas, then for you the computer and biological sciences clearly are dangerous.
To speak in literature with the perfect rectitude and insouciance of the movements of animals and the unimpeachable of the sentiment of trees in the woods and grass by the roadside is the flawless triumph of art.
Man is a rope stretched between the animal and the Superman-a rope over an abyss. A dangerous crossing, a dangerous wayfaring, a dangerous looking-back, a dangerous trembling and halting
He reflected on the decay of mankind-the decline of the human race into folly and weakness and rottenness. 'Be a good animal, true to your animal instinct' was his motto.
