Nature never makes excellent things, for mean or no uses: and it is hardly to be conceived, that our infinitely wise Creator, should make so admirable a Faculty, as the power of Thinking, that Faculty which comes nearest the Excellency of his own incomprehensible Being, to be so idlely and uselesly employ'd, at least 1/4 part of its time here, as to think constantly, without remembering any of those Thoughts, without doing any good to it self or others, or being anyway useful to any other part of Creation.
John LockeTruth certainly would do well enough, if she were once left to shift for herself...She is not taught by laws, nor has she any need of force, to procure her entrance into the minds of men.
John LockeIn the discharge of thy place set before thee the best examples; for imitation is a globe of precepts.
John LockeA father would do well, as his son grows up, and is capable of it, to talk familiarly with him; nay, ask his advice, and consult with him about those things wherein he has any knowledge or understanding. By this, the father will gain two things, both of great moment. The sooner you treat him as a man, the sooner he will begin to be one; and if you admit him into serious discourses sometimes with you, you will insensibly raise his mind above the usual amusements of youth, and those trifling occupations which it is commonly wasted in.
John LockeThe first step to get this noble and manly steadiness, is... carefully keep children from frights of all kinds, when they are young. ...Instances of such who in a weak timorous mind, have borne, all their whole lives through, the effects of a fright when they were young, are every where to be seen, and therefore as much as may be to be prevented.
John Locke
