Error is multiform (for evil is a form of the unlimited, as in the old Pythagorean imagery, and good of the limited), whereas success is possible in one way only (which is why it is easy to fail and difficult to succeed - easy to miss the target and difficult to hit it); so this is another reason why excess and deficiency are a mark of vice, and observance of the mean a mark of virtue: Goodness is simple, badness is manifold.

Goodness is to do good to the deserving and love the good and hate the wicked, and not to be eager to inflict punishment or take vengeance, but to be gracious and kindly and forgiving.

Character is made by many acts; it may be lost by a single one.

That in the soul which is called the mind is, before it thinks, not actually any real thing.

So it is clear that the search for what is just is a search for the mean; for the law is the mean.

In general, what is written must be easy to read and easy to speak; which is the same.

Peace is more difficult than war.
