This section – "The Laws of Temperaments" (also called "Laws of Ethics" and "Laws of Moral and Ethical Character") – contains eleven commands for Jews: five are positive commandments [what we should do] and six are negative commandments [what to refrain from doing]. These are the specifics:
One person has an angry temperament, they are always angry. And then there is a calm person who is not angry at all. And if this person does get angry, he or she will only be slightly angry, and even then, only once every few years. . . .
Chapters 1 and 2 - Personal character development is also addressed in a similar way in Maimonides' Commentary on the Mishnah in his "Introduction to the Chapters of the Fathers." We call this introduction, consisting of eight chapters, "The Eight Chapters" – Shemonah Perakim in Hebrew (sh'moh NAH p'rah KEEM).
In the middle between the extremes is an average temperament, equally distant from both extremes - Some call this middle way the "Golden Mean."
the person will be complete - In some manuscripts, this sentence adds and concludes with the words "in their bodies."
forbidden to follow, even according to the average - This means that the middle point – the average – is not the Golden Mean. The middle ground in some temperaments is not calculated with arithmetic. The measure of what makes for a good way of life (Chapter 1, Law 3) is the outcome. The outcome of any degree of arrogance is not likely to be desirable. Concerning arrogance, what seems to be extreme is the attitude and way of good conduct.
