We argue that the problem is not to "abandon"Marxism or to "annul" it,but to transcend it dialectically, just as Marx transcended Hegelian philosophy… - Murray Bookchin

The American left today as I know it—and believe me, I am very familiar with the American left—is going toward authoritarianism, toward totalitarianism. It's becoming the real right in the United States. 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. And in Europe, I would say that today the real support for State power and totalitarianism comes from the Communist parties and the Socialist parties and, where they are sizable, the Trotskyist groups. They are the ones that really frighten me.

Nor do piecemeal steps however well intended, even partially resolve problems that have reached a universal, global and catastrophic character. If anything, partial 'solutions' serve merely as cosmetics to conceal the deep seated nature of the ecological crisis. They thereby deflect public attention and theoretical insight from an adequate understanding of the depth and scope of the necessary changes.

It would be incredibly naive to suppose that Leninism was the product of a single man. The disease lies much deeper, not only in the limitations of Marxian theory but in the limitations of the social era that produced Marxism.
