The animal lacks both anxiety and hope because its consciousness is restricted to what is clearly evident and thus to the present moment: the animal is the present incarnate.
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.
I love him who laboureth and inventeth, that he may build the house for the Superman, and prepare for him earth, animal, and plant: for thus seeketh he his own down-going.
The male has more teeth than the female in mankind, and sheep and goats, and swine. This has not been observed in other animals.

Man is an essentially superstitious and fearful animal. Take away the herd's Christian gods and saints and they will without failing come to worship...something else.
... man was not born a carnivorous animal, but born to live on the fruits and herbs that the earth grows. I know we must all err. I would give up milk if I could, but I cannot. I have made that experiment times without number. I could not, after a serious illness, regain my strength, unless I went back to milk. That has been the tragedy of my life. But the basis of my vegetarianism is not physical, but moral. If anybody said that I should die if I did not take beef tea or mutton, even on medical advice, I would prefer death. That is the basis of my vegetarianism.
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.
It is necessary to correct the error that vegetarianism has made us weak in mind, or passive or inert in action. I do not regard flesh-food as necessary at any stage
The perfect woman is a higher type of humanity than the perfect man, and also something much rarer. The natural history of animals furnishes grounds in support of this theory.
