Power to do good is the true and lawful act of aspiring; for good thoughts (though God accept them), yet towards men are little better than good dreams, except they be put in act; and that cannot be without power and place, as the vantage and commanding ground.
John LockeHe that will make good use of any part of his life must allow a large part of it to recreation.
John LockeNobody is made anything by hearing of rules, or laying them up in his memory; practice must settle the habit of doing, without reflecting on the rule; and you may as well hope to make a good painter, or musician, extempore, by a lecture and instruction in the arts of music and painting, as a coherent thinker, or a strict reasoner, by a set of rules, showing him wherein right reasoning consists.
