The partiality we display, in so far as we form and sustain personal attachments, is not normatively fundamental. It is a by-product of the deference and responsiveness that are essential to our engagement with the world. We cannot form and sustain valuable personal relationships without seeing ourselves as answerable to the other participants in those relationships. And we cannot develop and sustain valuable projects without responding to the constraints imposed on our activities by the nature and requirements of those projects (...) themselves. More generally, we cannot engage with the world without responding differentially—or displaying partiality—with respect to the objects of our engagement. Partiality is thus a by-product of engagement. We cannot engage with the world at all without exhibiting forms of partiality. (shrink)
