Atopias argues for a transcendence that is a relation between thought and the world, rather than an object or a substance that escapes the world. In doing so, Atopies intervenes within the fields of object-oriented ontology and speculative realism, as well as classical philosophy, psychoanalysis, structuralism, poststructuralism, ecology, and global studies. The book posits that existence must be thought prior to being. Neyrat’s radical existentialism becomes the basis for a new theory of being, understood as the self-differentiation of the existent. Such self-differentiation, or spacing, is fundamentally different than the “Grand Divides” that postructuralist theories have critiqued. The first part of the book develops a critique of saturated immanence, or a world that attempts to immunize itself by rejecting forms of transcendence. From here the book turns to an internal divergence at the heart of philosophy, offering a new reading of Socrates. The second part of the book is a theory of the “trans-ject,” or an existing living being that is formed from the outside. The third section of the book examines the creation of metaphysical propositions through the transgression of the law of the excluded middle. Elaborating a politics of existence, Atopias calls us to defend the eccentricity of the living against that which prevents the living from existing.
