How have they lived; what have they made of life?
When circumstances invaded them with temptation, how did they meet temptation?

This solemn, silent, lonely, unworldly judgment of the whole case, done in God's presence, is, after the noisy, crowded, worldly judgment of it by Rome, after the rude humours of the law, and the terrible clashing of human passions, most impressive; and it rises into the majesty of old age in the summing up of the characters of Pompilia, Caponsacchi, and Guido.

I wish Browning had left it there.
