Nobody 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.
John LockeWhosoever will list himself under the banner of Christ, must, in the first place and above all things, make war upon his own lusts and vices. It is in vain for any man to usurp the name of Christian, without holiness of life, purity of manners, benignity and meekness of spirit.
John LockeThe difference, so observable in men's understandings and parts, does not arise so much from their natural faculties, as acquired habits.
John LockeAll men are liable to error; and most men are, in many points, by passion or interest, under temptation to it.
John LockeAll the entertainment and talk of history is nothing almost but fighting and killing: and the honour and renown that is bestowed on conquerors (who for the most part are but the great butchers of mankind) farther mislead growing youth, who by this means come to think slaughter the laudable business of mankind, and the most heroic of virtues.
