If you love only those who love you and to the extent that they love you, if you hold so strictly to this symmetry, mutuality, and reciprocity, then you give nothing, no love, and the reserve of your wages will be like a tax that is imposed or a debt that is repaid, like the acquittal of a debt. In order to deserve or expect an infinitely higher salary, one that goes beyond the perception of what is due, you have to give without taking account and love those who don’t love you.

Jacques Derrida, The Gift of Death

With respect to the external world, an initial sanity requires recognizing that I cannot live my skepticism, whereas with respect to others a final sanity requires recognizing that I can. I do.

Stanley Cavell
