This is a world in which each of us, knowing his limitations, knowing the evils of superficiality and the terrors of fatigue, will have to cling to what is close to him, to what he knows, to what he can do, to his friends and his tradition and his love, lest he be dissolved in a universal confusion and know nothing and love nothing.
It is at the same time a world in which none of us can find hieratic prescription or general sanction for any ignorance, any insensitivity, and indifference.
When a friend tells us of a new discovery we may not understand, we may not be able to listen without jeopardizing the work that is ours and closer to us; but we cannot find in a book or canon – and we should not seek – grounds for hallowing our ignorance.
If a man tells us that he sees differently than we or that he finds beautiful what we find ugly, we may have to leave the room, from fatigue or trouble; but that is our weakness and our default.
If we must live with a perpetual sense that the world and the men in it are greater than we and too much for us, let it be the measure of our virtue that we know this and seek no comfort.
Above all let us not proclaim that the limits of our powers correspond to some special wisdom in our choice of life, of learning, or of beauty.
