10. There is no nature which is inferior to art, for the arts imitate

the natures of things. But if this is so, that nature which is the most perfect and the most comprehensive of all natures, cannot fall short of the skill of art Now all arts do the inferior things for the sake of the superior; therefore the universal nature does so too. And, indeed, hence is the origin of justice, and in justice the other virtues have their foundation: for justice will not be observed, if we either care for middle things [things indifferent], or are easily deceived and careless and changeable (v. 16. 30; vii. 55).

11. If the things do not come to thee, the pursuits and avoidances of which disturb thee, still in a manner thou goest to them. Let then thy judgment about them be at rest, and they will remain quiet, and thou wilt not be seen either pursuing or avoiding.
