I'm sorry that some self-styled anarchists have picked up on the word spirit and have turned me into a theological ecologist, a notion which I think is crude beyond all belief.

I have a great admiration for pacifism, but I'm not a pacifist, mainly because I would defend myself if I were attacked.

I believe that anarchists should agree to disagree but not to fight with each other.

Here's what I do believe very strongly: that once capitalism comes into existence, once it creates this mythology of a stingy nature, then that myth has to be exorcised. In other words, we have to get out of people's heads the idea that without a market economy, without egotism, competition, rivalry and self-interest, without all the technological advances that [Karl] Marx imputed to capitalism, we have to eliminate the feeling that we would sink into some kind of barbarism.

There are no hierarchies in nature other than those imposed by hierarchical modes of human thought, but rather differences merely in function between and within living things.

I don't think that the Soviet Union and China are accidents, aberrations; I think they follow from Marxism-Leninism. I think that Leninism comes out of Marx's basic convictions.

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.
