3.2.1
There are three things (topics, τόποι ) in which a man ought to exercise himself who would be wise and good. The first concerns the desires and the aversions, that a man may not fail to get what he desires, and that he may not fall into that which he does not desire. The second concerns the movements (towards an object) and the movements from an object, and generally in doing what a man ought to do, that he may act according to order, to reason, and not carelessly. The third thing concerns freedom from deception and rashness in judgment, and generally it concerns the assents ( συγκαταθέσεις ). Of these topics the chief and the most urgent is that which relates to the affects ( τὰ πάθη, perturbations); for an affect is produced in no other way than by a failing to obtain that which a man desires or falling into that which a man would wish to avoid. This is that which brings in perturbations, disorders, bad fortune, misfortunes, sorrows, lamentations, and envy; that which makes men envious and jealous; and by these causes we are unable even to listen to the precepts of reason. The second topic concerns the duties of a man; for I ought not to be free from affects ( ἀπαθῆ ) like a statue, but I ought to maintain the relations ( σχέσεις ) natural and acquired, as a pious man, as a son, as a father, as a citizen.
