At first, too, the Doctor paid little attention to the moral and religious culture of his pupil; nor did he ever make a system of it. But by and by, though with a singular reluctance and kind of bashfulness, he began to extend his care to these matters; being drawn into them unawares, and possibly perceiving and learning what he taught as he went along. One evening, I know not how, he was betrayed into speaking on this point, and a sort of inspiration seized him. A vista opened before him: handling an immortal spirit, he began to know its requisitions, in a degree far beyond what he had conceived them to be when his great task was undertaken. His voice grew deep, and had a strange, impressive pathos in it; his talk became eloquent with depth of meaning and feeling, as he told the boy of the moral dangers of the world, for which he was seeking to educate him; and which, he said, presented what looked like great triumphs, and yet were the greatest and saddest of defeats. He told him that many things that seemed nearest and dearest to the heart of man were destructive, eating and gnawing away and corroding what was best in him; and what a high, noble, re-creating triumph it was when these dark impulses were resisted and overthrown; and how, from that epoch, the soul took a new start. He denounced the selfish greed of gold, lawless passion, revenge,--and here the grim Doctor broke out into a strange passion and zeal of anathema against this deadly sin, making a dreadful picture of the ruin that it creates in the heart where it establishes itself, and how it makes a corrosive acid of those genial juices. Then he told the boy that the condition of all good was, in the first place, truth; then, courage; then, justice; then, mercy; out of which principles operating upon one another would come all brave, noble, high, unselfish actions, and the scorn of all mean ones; and how that from such a nature all hatred would fall away, and all good affections would be ennobled.
I know not at what point it was, precisely, in these ethical instructions that an insight seemed to strike the grim Doctor that something more--vastly more--was needed than all he had said; and he began, doubtfully, to speak of man's spiritual nature and its demands, and the emptiness of everything which a sense of these demands did not pervade, and condense, and weighten into realities. And going on in this strain, he soared out of himself and astonished the two children, who stood gazing at him, wondering whether it were the Doctor who was speaking thus; until some interrupting circumstance seemed to bring him back to himself, and he burst into one of his great roars of laughter. The inspiration, the strange light whereby he had been transfigured, passed out of his face; and there was the uncouth, wild-bearded, rough, earthy, passionate man, whom they called Doctor Grim, looking ashamed of himself, and trying to turn the whole matter into a jest.
