In the aphorism titled “Love and Duality” in the second part of Human All Too Human, Friedrich Nietzsche concludes: “What else is love but understanding and rejoicing that another lives, works, and feels in a different and opposite way to ourselves ? That love may be able to bridge over the contrasts by joys, we must not remove or deny those contrasts. Even self-love presupposes an irreconcileable duality (or plurality) in one person.” The encounter of the lovers articulates their dissimilarity. It is not fusion, it is affirmation which abdicates the model of untarnished selfness. The “irreconcileable duality (or plurality)” is the law governing every encounter that wants to be an opening towards otherness, and be it the self-encounter which Nietzsche calls self-love in order to distinguish it from narcissistic self-misjudgment.The other is different – this is the first truth the loving subject tries to conform to. What proves to be the condition of possibility of love is the rift between the lovers. Rift or aporia, experience of duality or plurality which denies itself any unification. A sentence from Jacques Derrida’s Envois brings together this rift and its affirmation: “I have never so desired what I could not desire – this cry between us.”
