There's a sense in which Marx does contribute to the fund of human knowledge, and we can no more dismiss him than we can [George] Hegel or [Jean-Jacques] Rousseau or [Baruch] Spinoza or [Charles] Darwin; you don't have to be a Darwinian to appreciate Darwin's views, and I don't have to be a Marxist to appreciate what is valid in a number of [Karl] Marx's writings-and Marx would call that a form of simple commodity production rather than capitalism.

I believe that it's terribly important to have a movement that is spiritual, not in the supernatural sense, but in the sense of German Geist, spirit, which combines the idea of mind together with feeling, together with intuition.

I think that people who believe in limited government would benefit greatly by studying the logic in government itself and the role of power as a corruptive mechanism in leading finally to unlimited government.

I will not call myself a pacifist for the very simple reason that if something like a [Francisco] Franco should arise in Spain again, or, for that matter, in America, and tried to take away whatever dwindling civil liberties and human rights we retain, I would resist them with a club if I had to. But my admiration for pacifism as an outlook and a sensibility is enormous. I just find that it gets me into contradictions, as it often gets many pacifists into contradictory positions and strategies.

My thinking is very flexible, and I hope that it will remain flexible and creative as long as biology permits me to think and that I will remain a rebel all my life.

To speak of 'limits to growth' under a capitalistic market economy is as meaningless as to speak of limits of warfare under a warrior society.

If anarcho-communism served to regiment the population in the name of libertarian unity, if it served in any way through collectivist measures to deny the rights of the individual instead of reconciling the rights of the individual with the collective, I would definitely stand completely on the side of the individualist who is trying to rescue above all that most precious thing that makes us human - consciousness and personality.
