In love the individual goes beyond himself, beyond the narcissistic. In sex, you are really in a relationship with yourself via the mediation of the other. The other helps you to discover the reality of pleasure. In love, on the contrary the mediation of the other is enough in itself. Such is the nature of the amorous encounter: you go to take on the other, to make him or her exist with you, as he or she is.
Alain Badiou, In Praise of Love
