We don't have to go around as the Protestant reformation did, or as the socialist revolution did, and execute each other as soon as we are successful - assuming we'll ever be successful.

If we recognise that every ecosystem can also be viewed as a food web, we can think of it as a circular, interlacing nexus of plant animal relationships (rather than a stratified pyramid with man at the apex)… Each species, be it a form of bacteria or deer, is knitted together in a network of interdependence, however indirect the links may be.

I would not want to be in the same movement with an anarcho-syndicalist, however much I may respect and like that person. Some of my best friends are anarcho-syndicalists. I mean, I realize that we do not have a commonality, even a language, that makes it possible for us to communicate.

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.

Until society can be reclaimed by an undivided humanity that will use its collective wisdom, cultural achievements, technological innovations, scientific knowledge, and innate creativity for its own benefit and for that of the natural world, all ecological problems will have their roots in social problems.

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