" Dio Chrysostom (A.D. 40-115) in his first discourse on kingship, did not hesitate to point the lesson. "The good king," he wrote, "also believes it to be due to his position to have the larger portion, not of wealth, but of painstaking care and anxieties; hence he is actually more fond of toil than many are of pleasure or wealth. For he knows that pleasure, in addition to the general harm it does to those who constantly indulge there, also quickly renders them incapable of pleasure, whereas toil besides conferring other benefits, continually increases a man's capacity for toil.
