In the various enumerations of the moral virtues I had met with in my reading, I found the catalogue more or less numerous, as different writers included more or fewer ideas under the same name. Temperance, for example, was by some confined to eating and drinking, while by others it was extended to mean the moderating every other pleasure, appetite, inclination, or passion, bodily or mental, even to our avarice and ambition. I propos'd to myself, for the sake of clearness, to use rather more names, with fewer ideas annex'd to each, than a few names with more ideas; and I included under thirteen names of virtues all that at that time occurr'd to me as necessary or desirable, and annexed to each a short precept, which fully express'd the extent I gave to its meaning.
These names of virtues, with their precepts, were:
1. Temperance: Eat not to dullness. Drink not to elevation.
2. Silence: Speak not but what may benefit others or yourself. Avoid trifling conversation.
3. Order: Let all your things have their places. Let each part of your business have its time.
4. Resolution: Resolve to perform what you ought. Perform without fail what you resolve.
5. Frugality: Make no expense but to do good to others or yourself: i.e., Waste nothing.
6. Industry: Lose no time. Be always employed in something useful. Cut off all unnecessary actions.
7. Sincerity: Use no hurtful deceit. Think innocently and justly; and if you speak, speak accordingly.
8. Justice: Wrong none by doing injuries, or omitting the benefits that are your duty.
9. Moderation: Avoid extremes. Forbear resenting injuries so much as you think they deserve.
10. Cleanliness: Tolerate no uncleanness in body, clothes, or habitation.
11. Tranquility: Be not disturbed at trifles, or at accidents common or unavoidable.
12. Chastity: Rarely use venery but for health or offspring; never to dullness, weakness, or the injury of your own or another's peace or reputation.
13. Humility: Imitate Jesus and Socrates.”
