Our philosopher's moral code comprised the thirteen virtues of temperance, silence, order, resolution, frugality, industry, sincerity, justice, moderation, cleanliness, tranquility, chastity and humility. To each of these virtues Franklin attached a precept which makes edifying reading even at the present day: _temperance_, eat not to dullness, drink not to elation; _silence_, speak not but what may benefit others or yourself, avoid trifling conversation; _order_, let all your things have their places, let each part of your business have its time; _resolution_, resolve to perform what you ought, perform without fail what you resolve; _frugality_, make no expense, but do good to others or yourself, _i.e._, waste nothing; _industry_, lose no time, be always employed in something useful, cut off all unnecessary actions; _sincerity_, use no hurtful deceit, think innocently and justly, and if you speak, speak accordingly; _justice_, wrong no one by doing injury or omitting the benefits that are your duty; _moderation_, avoid extremes, forbear resenting injuries so much as you think they deserve; _cleanliness_, tolerate no uncleanliness in body, clothes or habitation; _tranquility_, be not disturbed by trifles or accidents common or unavoidable; _chastity_ (no remark); _humility_, imitate Jesus. This last virtue seems to have given Franklin very much concern; for he admits that he had the appearance of humility, and immediately adds that in reality there is no passion of the human breast so hard to subdue as pride. He is shrewd enough to say that "even if I could conceive that I had completely overcome it, I should probably be proud of my humility." Like many another, the virtue which gave him the most trouble was _order_, and this never became conspicuously apparent at any time of his long life.
