Take pains therefore to know what it is that thy nature requireth, and let nothing else distract thee. Thou hast already had sufficient experience, that of those many things that hitherto thou hast erred and wandered about, thou couldst not find happiness in any of them. Not in syllogisms, and logical subtilties, not in wealth, not in honour and reputation, not in pleasure. In none of all these. Wherein then is it to be found? In the practice of those things, which the nature of man, as he is a man, doth require. How then shall he do those things? if his dogmata, or moral tenets and opinions (from which all motions and actions do proceed), be right and true. Which be those dogmata? Those that concern that which is good or evil, as that there is nothing truly good and beneficial unto man, but that which makes him just, temperate, courageous, liberal; and that there is nothing truly evil and hurtful unto man, but that which causeth the contrary effects.
