I realize now that I was trying to undo by writing what could only be undone by action, not alone but with others—and through connections that incantation alone would not conjure. Words, it turned out, did not have all the performative powers that 1990s book-learning sometimes seemed to suggest. In the strange and wonderful final book of Leviathan, “On the Kingdom of Darkness,” Thomas Hobbes describes the job of thinking as untying superstitious knots that enmesh the mind. The superstition I recognized was neoliberal realism, which sets and polices the boundaries of the possible while pretending to map them objectively. But an equal and opposite superstition is the thought that language, style, and invocation could disperse those constraints, as if their being discourse meant they were only words, set to be scattered by other words.
