In every part of the universe we observe means adjusted with the nicest artifice to the ends which they are intended to produce; and in the mechanism of a plant, or animal body, admire how every thing is contrived for advancing the two great purposes of nature, the support of the individual, and the propagation of the species.
"It is essential to understand this point thoroughly: that the thing-in-itself, whether animal, vegetable, or mineral, is not only unknowable-it does not exist. This is important not only for sanity and peace of mind, but also for the most "practical" reasons of economics, politics, and technology.. This is not to say only that things exist in relation to one another, but that what we call "things" are no more than glimpses of a unified process. Certainly, this process has distinct features which catch our attention, but we must remember that distinction is not separation."
The policy of man consists, at first, in endeavoring to arrive at a state equal to that of animals, whom nature has furnished with food, clothing, and shelter.
Animal experimentation is the blackest of all the black crimes that a man is at present committing... We should be able to refuse to live if the price of living be the torture of sentient beings... I abhor [animal] experimentation with my whole soul. All the scientific discoveries stained with innocent blood I count as of no consequence... The greatness of a nation and its moral progress can be judged by the way its animals are treated.
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?
When great causes are on the move in the world, stirring all men's souls, drawing them from their firesides, casting aside comfort, wealth and the pursuit of happiness in response to impulses at once awe-striking and irresistible, we learn that we are spirits, not animals.
I have exposed myself and am not ashamed to stand there naked. "Shame" is what we call the monster that attached itself to men when they aspired beyond the animals.
For it is not metres, but a metre-making argument that makes a poem, - a thought so passionate and alive that like the spirit of a plant or an animal it has an architecture of its own, and adorns nature with a new thing.
We are the product of 4.5 billion years of fortuitous, slow biological evolution. There is no reason to think that the evolutionary process has stopped. Man is a transitional animal. He is not the climax of creation.
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.
I spend a hell of a lot of time killing animals and fish so I wouldn't kill myself. When a man is in rebellion against death, as I am in rebellion against death, he gets pleasure out of taking to himself one of the godlike attributes; that of giving it.
