"The Stoics did not shun worldly goods and pleasures or embrace discomfort out of masochism or to pursue spiritual atonement or purification, as was the case with the Greek Cynics or, in more modern times, by various religious ascetics and sects. Rather, the Stoics advocated occasional, deliberate use of temporary poverty, voluntary discomfort, and refraining from pleasures in order to quiet their appetites for material goods and sensual pleasures, increase the sense of appreciation for what they already had, and — most importantly — to “immunize” themselves against future misfortune and develop the courage to take on difficult challenges. In
The Discourses, a set of lectures transcribed by his student Arrian, Epictetus advocates the intentional use of hardship as a form of active training to build up one’s strength, and he acknowledges that this is a gradual process:
But neither a bull nor a noble-spirited man comes to be what he is all at once; he must undertake hard winter training, and prepare himself, and not propel himself rashly into what is not appropriate to him. (TD, Book One, Ch. 2, p. 10)
One criticism that has been lodged against the use of voluntary discomfort or hardship is that it is just too hard and too unpleasant for the average person. Some people may be born with a higher threshold for pain, but for most of us this type of self-inflicted discomfort does not look very appealing or fruitful. To this, Irvine has a good answer:
What the Stoics discover, though, is that willpower is like muscle power: The more they exercise their muscles, the stronger they get, and the more they exercise their will, the stronger it gets. Indeed, by practicing Stoic self-denial techniques over a long period, Stoics can transform themselves into individuals remarkable for their courage and self-control. They will be able to do things that others dread doing, and they will be able to refrain from doing things that others cannot resist doing. They will, as a result, be thoroughly in control of themselves. This self-control makes it far more likely that they will attain the goals of their philosophy of life, and this in turn dramatically increases their chances of living a good life."
