The business of education is not to make the young perfect in any one of the sciences, but so to open and dispose their minds as may best make them - capable of any, when they shall apply themselves to it.
John LockeEarthly minds, like mud walls, resist the strongest batteries; and though, perhaps, sometimes the force of a clear argument may make some impression, yet they nevertheless stand firm, keep out the enemy, truth, that would captivate or disturbe them.
John LockeMathematical proofs, like diamonds, are hard and clear, and will be touched with nothing but strict reasoning.
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.
