I regard Marxism as the most sinister and the most subtle form of totalitarianism.

I've had training in electronics engineering, of all things, and in languages. But I've never taken any degree, something I share with Lewis Mumford, I think.

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 learned that [Trotskyism] were no different from the Stalinists, and they expelled me, which is the typical Marxist-Leninist way of dealing with dissenters. From that point on, I migrated by the 1950s into anarchism, increasingly emphasizing decentralization. Also, I made the all-important step of bridging my social philosophy with ecology. I did that in 1952 and went on to write a whole series of books developing an anarcho-ecological approach.

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.

Terms that are related to individuals like Marxist, or Hegelian, or Bakuninist, or Kropotkinist, are completely outside my intellectual and emotional horizon. I'm a follower of no one.

When I talk about self-management, self-regulation, self-government, the word I emphasize is self, and my concern is with the reconstruction of the self. Marxists and even many, I think, overly enthusiastic anarchists have neglected that self.
