When Allan saw that Jo was nearing the end, he said:

“Jo! Did you ever know a prayer?”

“Never know’d nothink, sir.”

“Not so much as one short prayer?”

“No, sir. Nothink at all. Mr. Chadband he was a-prayin’ wunst at Mr. Snagsby’s and I heerd him, but he sounded as if he wos a-speakin’ to hisself, and not to me. He prayed a lot, but I couldn’t make out nothink on it. Different times, there was other genlmen come down Tom-all-Alone’s a-prayin’, but they all mostly sed as the t’other wuns prayed wrong, and all mostly sounded to be a-talkin’ to theirselves, or a-passin’ blame on the t’others, and not a-talkin’ to us. We never know’d nothink. I never know’d what it wos all about.”

No? Mr. Chadband, your long sermon about “the Terewth” found no place in Jo in which to rest; nothing to which it could attach itself. No wonder he went asleep. He had no apperceptive centres in his experience or his training to which your kind of religious teaching was related.

Poor Jo! He was the first great illustration, and he is still the best, of the great pedagogical truth, that we see, and hear, and understand in all that is around us only what corresponds to what we are within; that our power to see, and hear, and understand increases as our inner life is cultured and developed; and that a life as barren as that of the great class of whom Jo was made the type makes it impossible to comprehend any teaching of an abstract kind. This revelation is of course most valuable to primary teachers in cities.

Dickens showed his wonderful insight into the most profound problems of psychology in his great character sketch of poor Jo. He agreed with Herbart regarding the philosophy of apperception so far as it related to intellectual culture, but he painted Jo entirely out of harmony with Herbart’s psychology in relation to soul development. After describing Mr. Chadband’s sermon on “Terewth” Dickens says:

All this time Jo has been standing on the spot where he woke up, ever picking his cap, and putting bits of fur in his mouth. He spits them out with a remorseful air, for he feels that it is in his nature to be an unimprovable reprobate, and it’s no good his trying to keep awake, for he won’t never know nothink. Though it may be, Jo, that there is a history so interesting and affecting even to minds as near the brutes as thine, recording deeds done on this earth for common men, that if the Chadbands, removing their own persons from the light, would but show it thee in simple reverence, would but leave it unimproved, would but regard it as being eloquent enough without their modest aid—it might hold thee awake, and thou might learn from it yet!

Jo never heard of any such book. Its compilers, and the Reverend Chadband, are all one to him—except that he knows the Reverend Chadband, and would rather run away from him for an hour than hear him talk for five minutes.
