John Locke - Some thoughts on Education

"For extravagant young fellows, that have liveliness and spirit, come sometimes to be set right, and so make able and great men: but dejected minds, timorous and tame, and low spirits, are hardly ever to be raised, and very seldom attain to anything. To avoid the danger that is on either hand is the great art: and he that has found a way how to keep up a child's spirit, easy, active, and free; and yet, at the same time, to restrain him from many things he has a mind to, and to draw him to things that are uneasy to him; he, I say, that knows how to reconcile these seeming contradictions, has, in my opinion, got the true secret of education." ~ John Locke, Some Thoughts Concerning Education
