 More specific therapeutic techniques may also be of use to the one making ethical progress. Epictetus recommends that pupils refrain from using the terms “good” and “bad,” not because those terms have no application in human life, but because they are too easily misapplied. Thus one should “suppress” desire and aversion, and use only plain, emotionally unadorned impulse and counter-impulse (Encheiridion 2). To combat some individual bad habit, one should practice the opposite behavior: for instance, if one is quick tempered, one should accustom oneself to bearing insults with patience (3.12.6–12). Regular self-examination at bedtime—a practice borrowed from the Pythagorean tradition—will enable one to correct errors before they become ingrained (3.10.1).
