It is curious that physical courage should be so common in the world and moral courage so rare.

Physical bravery is not cheap, and many people have found it in themselves when danger arrived. Moral courage is scarcer, perhaps because it usually has to be found alone, with no comrades beside you and nobody on your side of the room. Its cost arrives slowly, as exclusion rather than injury.

Look for the moment this week when you know what should be said and everyone has settled on not saying it. You need one sentence, not a speech, and a willingness to be uncomfortable afterwards. Whether you take it measures your nerve better than anything dramatic.
