...innocence is not safe in a civilization like ours, where a man must practice a 'ruled undemonstrative distrustfulness' in order to defend himself against traps. This 'ruled undemonstrative distrustfulness' is not confined to business men, but exists everywhere. We all exercise it. I know I do, and I should be surprised if you, who are listening to me, didn't. All we can do (and Melville gives us this hint) is to exercise it consciously, as Captain Vere did. It is unconscious distrustfulness that corrodes the heart and destroys the heart's insight, and prevents it from saluting goodness.
