How might we of the Undercommons avail ourselves in light of Climate Strike? Do we have concepts we could offer, lessons we could share? What is this Magnificence all around us? How do we help it grow? Who do we want to become? Hardt and Negri have told us, in a “script that is by now familiar” (xiii), that for most powerful social movements today, “leadership” is a dirty word. One of us rightly asks, “Is the youthful movement against fossil fuels leaderless? What about Greta Thunberg?” She’s a sort of leader, certainly — but perhaps the leadership she provides is tactical rather than strategic, a distinction favored by Hardt and Negri. By this they mean leadership of an entrepreneurial sort, “limited to short-term action and tied to specific occasions” (Assembly, p. 19). Hardt and Negri craft openings for which we’re grateful. I appreciate their call, too, at the end of Assembly, for a Hephaestus, a three-faced Dionysus, and a Hermes of the common. Why those three, however, as the constituents of their pantheon of the common? And how do we get from there to putting the machines back in the hands of living labor? How do we mute the command of capital? What would it mean, for instance, to make “digital algorithms” common, a form of non-property open to use by the multitude? Perhaps it’s as simple as forging “an instrument endowed with magical powers,” like the shield Hephaestus forged for Achilles. This instrument would “depict in concentric circles the composition of the entire community,” thus giving expression to “a new civilization, new modes of life, a new figure of humanity, and new relations of care among living species and the earth, up to the cosmos” (Assembly, p. 274).
