Alain Badiou
Love is a procedure of truth with which two identify as one: fidelity to a bond, created up until now, makes it so. Alain Badiou points to say it could be you who finds this truth.

On love, Alain Badiou (pictured) writes this in Being and Event:

'Beneath itself, it exists; beyond itself, it inexists. It can always be said that it is an almost-nothing of the state, or that it is a quasi-everything of the situation. If one determines its concept, the famous "so we are nothing, let's be everything" [nous ne sommes rien, soyons tout] touches upon this point. In the last resort it means: let's be faithful to the event we are.'

In other words, two humans consummate their fidelity to the events that brought them together with the declaration of love. They become the subjects of this fidelity, both committed to their shared cause: to one bond. They constantly reinvent life to experience the truth of what it is to be two and not one.

Love, therefore, is a procedure of truth; and, with fidelity, Badiou offers a logic for declaring this truth (of the Two). This is the logic of love.

Why is that so good?
