In response to the charge of hubris and Prometheanism, it is just as important to emphasize that though we accept the inevitability of attempting to “plan” nature, the socialist project does not aim at controlling nature. Nature is never under our control, and there are always unintended consequences. But just as we cannot trust either the market or a policy elite to automatically produce just economic outcomes, we cannot assume that an unmolested nature will provide us with a safe and abundant world in which to live, in this or any other social system. And so, in the process of achieving the post-scarcity order that the Marxist biologist David Schwartzman calls “solar communism,” we will take up the task of cleaning up the mess capitalism has made, and creating an Anthropocene more rational, democratic, and egalitarian than the one we now inhabit.
