Synthesized answer
The central thesis of Peter Sloterdijk's text "Spheres" reinterprets the history of Western metaphysics. Sloterdijk proposes that this history is not primarily focused on temporality, but rather on spatial and immunological projects [Passage 1]. He describes his work as an "epic project" that examines spatiality from the concept of the self (bubble), to the exploration of the world (globe), and finally to the poetics of plurality (foam) [Passage 1].

He identifies the question of being as intrinsically linked to the "aerial technology of architectonics and anthropogenesis" [Passage 1].
