"Power is not a means; it is an end. One does not establish a dictatorship in order to safeguard a revolution; one makes the revolution in order to establish the dictatorship. The object of persecution is persecution. The object of torture is torture. The object of power is power."
"He was a lonely ghost uttering a truth that nobody would ever hear."
"At present nothing is possible except to extend the area of sanity little by little. We cannot act collectively. We can only spread our knowledge outwards from individual to individual, generation after generation."
