LET it be thy earnest and incessant care as a Roman and a man to perform whatsoever it is that thou art about, with true and unfeigned gravity, natural affection, freedom and justice: and as for all other cares, and imaginations, how thou mayest ease thy mind of them. Which thou shalt do; if thou shalt go about every action as thy last action, free from all vanity, all passionate and wilful aberration from reason, and from all hypocrisy, and self-love, and dislike of those things, which by the fates, or appointment of God, have happened unto thee.
