Here are Judith Butler’s wise words:
“Precariousness implies living socially, that is, the fact that one’s life is always in some sense in the hands of the other. It implies exposure both to those we know and to those we do not know; a dependency on people we know, or barely know, or know not at all. Reciprocally, it implies being impinged upon by the exposure and dependency of others, most of whom remain anonymous. These are not necessarily relations of love or even care, but constitute obligations toward others, most of whom we cannot name and do not know, and who may or may not bear traits of familiarity to an established sense of who “we” are. In the interest of speaking in common parlance, we could say that “we” have such obligations to “others” and presume that we know who “we” are in such an instance. The social implication of this view, however, is precisely that the “we” does not, and cannot, recognize itself, that it is riven from the start, interrupted by alterity, as Levinas has said, and the obligations “we” have are precisely those that disrupt any established notion of the “we”.’
