"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."
