To grieve, and to make grief itself into a resource of politics, is not to be resigned to inaction, but it may be understood as the slow process by which we develop a point of identification with suffering itself […] Then we might critically evaluate and oppose the conditions under which certain human lives are more grievable than others. From where might a principle emerge by which we vow to protect others from the kinds of violence we have suffered, if not from an apprehension of a common human vulnerability?
Judith Butler, Precarious Life, 2004
