Violence as a tool is already operating in the world before anyone takes it up: that fact alone neither justifies nor discounts the use of the tool. What seems most important, however, is that the tool is already part of a practice, presupposing a world conducive to its use; that the use of the tool builds or rebuilds a specific kind of world, activating a sedimented legacy of use. When any of us commit acts of violence, we are, in and through those acts, building a more violent world.

Lives matter in the sense that they assume physical form within the sphere of appearance; lives matter because they are to be valued equally.

It is precisely because we can destroy that we are under an obligation to know why we ought not to do it, and to summon those countervailing powers that curb our destructive capacity. Nonviolence becomes an ethical obligation by which we are bound precisely because we are bound to one another; it may well be an obligation against which we rail, in which ambivalent swings of the psyche make themselves known, but the obligation to preserve the social bond can be resolved upon without precisely resolving that ambivalence. The obligation not to destroy each other emerges from, and reflects, the vexed social form of our lives, and it leads us to reconsider whether self-preservation is not linked to preserving the lives of others.
