“The minotaur more than justifies the existence of the labyrinth.”

Two in the Bush (1966)
Context: The attitude of the average person to the world they live in is completely selfish. When I take people round to see my animals, one of the first questions they ask (unless the animal is cute and appealing) is, "what use is it?" by which they mean, "what use is it to them?" To this one can reply "What use is the Acropolis?" Does a creature have to be of direct material use to mankind in order to exist? By and large, by asking the question "what use is it?" you are asking the animal to justify its existence without having justified your own.

Ordinary Men and Women
Naked Lunch (1959)
Context: The end result of complete cellular representation is cancer. Democracy is cancerous, and bureaus are its cancer. A bureau takes root anywhere in the state, turns malignant like the Narcotic Bureau, and grows and grows, always reproducing more of its own kind, until it chokes the host if not controlled or excised. Bureaus cannot live without a host, being true parasitic organisms. (A cooperative on the other hand can live without the state. That is the road to follow. The building up of independent units to meet needs of the people who participate in the functioning of the unit. A bureau operates on opposite principles of inventing needs to justify its existence.) Bureaucracy is wrong as a cancer, a turning away from the human evolutionary direction of infinite potentials and differentiation and independent spontaneous action to the complete parasitism of a virus. (It is thought that the virus is a degeneration from more complex life-form. It may at one time have been capable of independent life. Now has fallen to the borderline between living and dead matter. It can exhibit living qualities only in a host, by using the life of another — the renunciation of life itself, a falling towards inorganic, inflexible machine, towards dead matter.) Bureaus die when the structure of the state collapse. They are as helpless and unfit for independent existence as a displaced tapeworm, or a virus that has killed the host.

Speech in Boston (2002)
Context: In our struggle against apartheid, the great supporters were Jewish people. They almost instinctively had to be on the side of the disenfranchised, of the voiceless ones, fighting injustice, oppression and evil. I have continued to feel strongly with the Jews. I am patron of a Holocaust centre in South Africa. I believe Israel has a right to secure borders.
What is not so understandable, not justified, is what it did to another people to guarantee its existence. I've been very deeply distressed in my visit to the Holy Land; it reminded me so much of what happened to us black people in South Africa.
