One Divides Into Two: Dialectics, Negativity and Clinamen

’One splits into two, two doesn’t merge into one’. The slogan made quite a stir in its day, combining the air of a purely mathematical axiom with a political mandate. Under the cloak of a universal truth there lies a political dagger. The formula combines under the same heading a mathematical adage, an ontological statement, and a political stance. So why does one split into two, necessarily, in mathematics, in ontology, and in politics? And why, once we arrive at Two, at a foundational split, can we never return to the supposed unity of One? The different lectures will explore this problem from Hegel to Lacan, from sexuality to politics.
