“This is not some special law or guideline for artists and writers. It is a general principle for all citizens. It is a fundamental principle of the revolution. Counterrevolutionaries, that is, the enemies of the revolution, have no rights against the revolution, because the revolution has one right: the right to exist, the right to develop, and the right to be victorious.”

Context: The right of revolution is an inherent one. When people are oppressed by their government, it is a natural right they enjoy to relieve themselves of the oppression, if they are strong enough, either by withdrawal from it, or by overthrowing it and substituting a government more acceptable. But any people or part of a people who resort to this remedy, stake their lives, their property, and every claim for protection given by citizenship — on the issue. Victory, or the conditions imposed by the conqueror — must be the result.

Context: I am convinced that if we are to get on the right side of the world revolution, we as a nation must undergo a radical revolution of values. We must rapidly begin the shift from a "thing-oriented" society to a "person-oriented" society. When machines and computers, profit motives and property rights are considered more important than people, the giant triplets of racism, materialism, and militarism are incapable of being conquered.
