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

Humanity has passed through a long history of one-sidedness and of a social condition that has always contained the potential of destruction, despite its creative achievements in technology. The great project of our time must be to open the other eye: to see all-sidedly and wholly, to heal and transcend the cleavage between humanity and nature that came with early wisdom.

We don't have an appreciable American left any more in the United States. What I saw of the SDS in the '60s was very abhorrent to me: Marxism, Leninism, almost the KGB mentality - a police politics that I found completely totalitarian in nature.

I'm not sitting in judgment on whether or not libertarians can participate in a political process whose very nature they oppose.

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.

We are part of nature, a product of a long evolutionary journey. To some degree, we carry the ancient oceans in our blood. … Our brains and nervous systems did not suddenly spring into existence without long antecedents in natural history. That which we most prize as integral to our humanity - our extraordinary capacity to think on complex conceptual levels - can be traced back to the nerve network of primitive invertebrates, the ganglia of a mollusk, the spinal cord of a fish, the brain of an amphibian, and the cerebral cortex of a primate.

The State certainly played a decisive role. I also believe that it may have stemmed from the rivalry itself. Grow or die, devour or die. That's the one problem that I have to wrestle with. I have to wrestle with whether or not rivalry in the free market does not ultimately lead to concentration, corporatism, and finally totalitarianism.
