Let the awe [the teacher] has upon [children's] minds be so tempered with the constant marks of tenderness and good will, that affection may spur them to their duty, and make them find a pleasure in complying with his dictates. This will bring them with satisfaction to their tutor; make them hearken to him, as to one who is their friend, that cherishes them, and takes pains for their good; this will keep their thoughts easy and free, whilst they are with him, the only temper wherein the mind is capable of receiving new information, and of admitting into itself those impressions.
John LockeCertainly great persons had need to borrow other men's opinions to think themselves happy; for if they judge by their own feeling, they cannot find it: but if they think with themselves what other men think of them, and that other men would fain be as they are, then they are happy as it were by report, when, perhaps, they find the contrary within.
John LockeReading furnishes the mind only with materials of knowledge; it is thinking that makes what we read ours.
