"I had long put on one side the purist pacifist view that one should have nothing to do with a social revolution if any violence were involved... Nevertheless, the conviction remained in my mind that any revolution would fail to establish freedom and fraternity in proportion to its use of violence, that the use of violence inevitably brought in its train domination, repression, cruelty."
