Censorship is not an occupation that attracts intelligent, subtle minds. Censors can and often have been outwitted. But the game of slipping Aesopian messages past the censor is ultimately a sterile one, diverting writers from their proper task.

Where civilization entailed the corruption of barbarian virtues and the creation of dependent people, I decided, I was opposed to civilization.

Some years ago I wrote a book called The House on Eccles Street. To write this book I had to think my way into the existence of Marion Bloom...Marion Bloom was a figment of James Joyce's imagination. If I can think my way into the existence of a being who has never existed, then I can think my way into the existence of a bat or a chimpanzee or an oyster, any being with whom I share the substrate of life.

...the program of scientific experimentation that leads you to conclude that animals are imbeciles is profoundly anthropocentric. It values being able to find your way out of a sterile maze, ignoring the fact that if the researcher who designed the maze were to be parachuted into the jungles of Borneo, he or she would be dead of starvation in a week...If I as a human being were told that the standards by which animals are being measured in these experiments are human standards, I would be insulted.

If it is indeed impossible - or at least very difficult - to inhabit the consciousness of an animal, then in writing about animals there is a temptation to project upon them feelings and thoughts that may belong only to our own human mind and heart.

Temperament is fixed, set. The skull, followed by the temperament: the two hardest parts of the body. Follow your temperament. It is not a philosophy, It is a rule, like the Rule of St Benedict.

But the truth, he knows, is otherwise. His pleasure in living has been snuffed out. Like a leaf on a stream, like a puffball on a breeze, he has begun to float towards his end. He sees it quite clearly, and it fills him with (the word will not go away) despair. The blood of life is leaving his body and despair is taking its place, despair that is like a gas, odourless, tasteless, without nourishment. You breathe it in, your limbs relax, you cease to care, even at the moment when the steel touches your throat.
