Why this book is cool:

It’s an outline of a complete anarchist way of being, building from metaphysics and the structure of our thought, to ethics, politics, and cosmology.

It centres around critiquing our conceptions of the human and humanism, and finding a way to do identity politics without reifying the identities we want to unmake.
Instead of going for a simple anti-humanism, it proposes an anti-authoritarian human, nothing like the one we must destroy that we have now, but instead the human as a set of relations of anarchy. This is the coolest part of the book.

The metaphysics is Deleuzean, and though Deleuze is hard, it’s explained in relatively simple and easy-to-digest terms in the book - not easy but not super obscure. If you’re interested in dipping your toes into Deleuzean thinking, I think this is a good introduction.
(There are a lot of other badass scholars and anti-colonials considered [Fanon, Césaire, Wynter, Hartman], but I would call this book pretty Deleuzean, since part 2 about Mbembe is rooted in Mbembe’s Deleuzean metaphysics.)

It’s purely anti-authoritarian (i.e. non-left) anarchism, a reparative insurrectionism that has has absorbed post-left critique, is anti-civ, and deals with notions of time and prefiguration, calling it ‘insurrectionary time’. With the anarchist notion of the human it also has an anarchist version of human rights that overcomes all the usual arguments I and others generally post around here.

It’s a anticolonial text that provides a framework an anti-authoritarian form of reparations.

It’s got a long-ass name:
Establishing an immanent counterhumanism for the un-foreclosure of the future: Deleuze, Mbembe, Hartman and the anarchic Open World

I recommend you read the intro and then the contents to get a sense of what it looks like and its structure.

(And yeah, this person and the surrounding people are where I get a lot of my ideas from)
