One day when re-reading A Dominie's Log, its author decided that a book is out of date five minutes after it is written. In other words, he was in doubt—terrible and perplexing doubt. Do I really understand children? he asked himself. Are my ideas upon education right or wrong ? He decided that he had not sufficiently studied the psychology of children and that, in consequence, he had been guilty of almost criminal neglect. In the same delightfully discursive and humorous manner the Dominic reveals himself, as attractive in his doubts as in his convictions. He does not repent his unconventions. On the contrary, he reproaches himself for having been a heretic, whereas he ought to have been an arch-heretic.
