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 Locke
