Any time and any place can be used to study: his room, a garden, is table, his bed; when alone or in company; morning and evening. His chief study will be Philosophy, that Former of good judgement and character who is privileged to be concerned with everything.

In true education, anything that comes to our hand is as good as a book: the prank of a page- boy, the blunder of a servant, a bit of table talk - they are all part of the curriculum.

A tutor should not be continually thundering instruction into the ears of his pupil, as if he were pouring it through a funnel, but, after having put the lad, like a young horse, on a trot, before him, to observe his paces, and see what he is able to perform, should, according to the extent of his capacity, induce him to taste, to distinguish, and to find out things for himself; sometimes opening the way, at other times leaving it for him to open; and by abating or increasing his own pace, accommodate his precepts to the capacity of his pupil.
