I argue against purism not because I want a devastated world, the Mordor of industrial capitalism emerging as from a closely aligned alternate universe through our floating islands of plastic gradually breaking down into microbeads consumed by the scant marine life left alive after generations of overfishing, bottom scraping, and coral reef–killing ocean acidification; our human-caused, place-devastating elevated sea levels; our earth-shaking, water poisoning fracking; our toxic lakes made of the externalities of rare-earth mineral production for so-called advanced electronics; our soul-and-lifedestroying prisons; our oil spills; our children playing with bits of dirty bombs; our white phosphorus; our generations of trauma held in the body; our cancers; and I could go on. I argue against purism because it is one bad but common approach to devastation in all its forms. It is a common approach for anyone who attempts to meet and control a complex situation that is fundamentally outside our control. It is a bad approach because it shuts down precisely the field of possibility that might allow us to take better collective action against the destruction of the world in all its strange, delightful, impure frolic. Purism is a de-collectivizing, de-mobilizing, paradoxical politicsof despair. This world deserves better.
