If you punish him for what he sees you practise yourself, he... will be apt to interpret it the peevishness and arbitrary imperiousness of a father, who, without any ground for it, would deny his son the liberty and pleasure he takes himself.
John LockeLet 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 LockeAs usurpation is the exercise of power which another has a right to, so tyranny is the exercise of power beyond right, which nobody can have a right to.
John Locke
