Reprehend not the imperfection of others, for that belongs to parents, masters and superiors.
Gaze not on the marks or blemishes of others, and ask not how they came. What you may speak in secret to your friend deliver not before others.
Speak not in an unknown tongue in company, but in your own language; and that as those of quality do, and not as the vulgar. Sublime matters treat seriously.
Think before you speak; pronounce not imperfectly, nor bring out your words too heartily, but orderly and distinctly.
When another speaks, be attentive yourself, and disturb not the audience. If any hesitate in his words, help him not, nor prompt him without being desired; interrupt him not, nor answer him till his speech be ended.
Treat with men at fit times about business, and whisper not in the company of others.
Make no comparisons; and if any of the company be commended for any brave act of virtue, commend not another for the same.
Be not apt to relate news if you know not the truth thereof. In discoursing of things that you have heard, name not your author always. A secret discover not.
Be not curious to know the affairs of others, neither approach to those who speak in private.
Undertake not what you cannot perform; but be careful to keep your promise.
