Their pupils and their little charges are not nourished and fed by what they learn: the learning is passed from hand to hand with only one end in view: to show it off, to put into our accounts to entertain others with it, as though it were merely counters, useful for totting up and producing statements, but having no other use or currency. 'Apud alios loqui didicerunt, non ipsi secum' [They have learned how to talk with others, not with themselves]

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.
