" someone who practices Stoic principles “must, whether he wills or not, necessarily be attended by constant cheerfulness and a joy that is deep and issues from deep within, since he finds delight in his own resources, and desires no joys greater than his inner joys.” Furthermore, compared to these joys, pleasures of the flesh are “paltry and trivial and fleeting.”6 "
