Violence’ For if violence is a means, a criterion for criticizing it might seem immediately available. It imposes itself in the question... whether violence, in a given case, is a means to just or an unjust end. A critique of it would then be implied in a system of just ends. This, however, is not so. For what such a system, assuming it to be secure against all doubt, would contain is not a criterion for violence itself as a principle, but, rather, the criterion for cases of its use. The question would...
