 Furthermore, social ecologists and anarchists tend to focus on the state alone, rather than the class relations behind state domination (in the view of Marxists).Kovel fears that this is political, springing from historic hostility to Marxism among anarchists and sectarianism, which he points out as a fault of the "brilliant" but "dogmatic" founder of Social Ecology, Murray Bookchin.For Kovel and Lowy, eco-socialism is "the realization of the 'first-epoch' socialisms" by resurrecting the notion of "free development of all producers", distancing themselves from "the attenuated, reformist aims of social democracy and the productivist structures of the bureaucratic variations of socialism", such as forms of Leninism and Stalinism.
