That heart where self has found no place and raised no throne is slow to recognise its ugly presence when it looks upon it. As one possessed of an evil spirit was held in old time to be alone conscious of the lurking demon in the breasts of other men, so kindred vices know each other in their hiding places every day, when virtue is incredulous and blind.

There is no more suggestive work on the contents of children’s minds than Bleak House. When Poor Jo was summoned to give evidence at the inquest he was questioned in regard to himself and his theology. The results were startling.

Name, Jo. Nothing else that he knows on. Don’t know that everybody has two names. Never heerd of sich a think. Don’t know that Jo is short for a longer name. Thinks it long enough for him. He don’t find no fault with it. Spell it? No. He can’t spell it. No father, no mother, no friends. Never been to school. What’s home? Knows a broom’s a broom, and knows it’s wicked to tell a lie. Don’t recollect who told him about the broom, or about the lie, but knows both. Can’t exactly say what’ll be done to him after he’s dead if he tells a lie to the gentlemen here, but believes it’ll be something wery bad to punish him, and serve him right—and so he’ll tell the truth.

Jo sweeps his crossing all day long, unconscious of the link, if any link there be. He sums up his mental condition, when asked a question, by replying that he “don’t know nothink.” He knows that it’s hard to keep the mud off the crossing in dirty weather, and harder still to live by doing it. Nobody taught him, even that much; he found it out.

Jo comes out of Tom-all-Alone’s, meeting the tardy morning, which is always late in getting down there, and munches his dirty bit of bread as he comes along. His way lying through many streets, and the houses not yet being open, he sits down to breakfast on the doorstep of the Society for the Propagation of the Gospel in Foreign Parts, and gives it a brush when he has finished, as an acknowledgment of the accommodation. He admires the size of the edifice, and wonders what it’s all about. He has no idea, poor wretch, of the spiritual destitution of a coral reef in the Pacific, or what it costs to look up the precious souls among the cocoanuts and breadfruits.

He goes to his crossing, and begins to lay it out for the day. The town awakes; the great teetotum is set up for its daily spin and whirl; all that unaccountable reading and writing, which has been suspended for a few hours, recommences. Jo and the other lower animals get on in the unintelligible mess as they can. It is market day. The blinded oxen, overgoaded, overdriven, never guided, run into wrong places and are beaten out; and plunge, red-eyed and foaming, at stone walls; and often sorely hurt the innocent, and often sorely hurt themselves. Very like Jo and his order; very, very like!

A band of music comes and plays. Jo listens to it. So does a dog—a drover’s dog, waiting for his master outside a butcher’s shop, and evidently thinking about those sheep he has had upon his mind for some hours, and is happily rid of. He seems perplexed respecting three or four; can’t remember where he left them; looks up and down the street, as half expecting to see them astray; suddenly pricks up his ears and remembers all about it. A thoroughly vagabond dog, accustomed to low company and public houses; a terrific dog to sheep; ready at a whistle to scamper over their backs, and tear out mouthfuls of their wool; but an educated, improved, developed dog, who has been taught his duties and knows how to discharge them. He and Jo listen to the music, probably with much the same amount of animal satisfaction; likewise, as to awakened association, aspiration, or regret, melancholy or joyful reference to things beyond the senses, they are probably upon a par. But, otherwise, how far above the human listener is the brute!

Turn that dog’s descendants wild, like Jo, and in a very few years they will so degenerate that they will lose even their bark—but not their bite.

When Lady Dedlock met Jo, she asked him:

“Are you the boy I’ve read of in the papers?”
