Beyond the question of certainty is the question of detachment. The process by which principles are discovered and appropriated is other than that by which, in practice, they are applied; and our most sacred and disinterested convictions ought to take shape in the tranquil regions of the air, above the tumult and the tempest of active life. For a man is justly despised who has one opinion in history and another in politics, one for abroad and another at home, one for opposition and another for office. History compels us to fasten on abiding issues, and rescues us from the temporary and transient. Politics and history are interwoven, but are not commensurate. Ours is a domain that reaches farther than affairs of state, and is not subject to the jurisdiction of governments.
