5 Others again suppose, that to enjoy good health is the source of pleasure. But it is not so. For many of those who enjoy good health have a thousand times wished themselves dead, not being able to bear the insults inflicted on them. Others again affirm, that to enjoy glory, and to have attained to power, and to administer the highest offices, and to be flattered by multitudes, is productive of continual gladness. But neither is this the case. And why do I speak of other offices of power?
For although we were to mount up in thought to royalty itself, and to him who lives in that station, we should find it encompassed with a diversity of troubles, and having so many necessary causes the more of sadness, in proportion as it is surrounded with a greater weight of affairs. And what need is there to speak of wars, and battles, and the insurrections of barbarians? Oftentimes he has reason to fear those by whom he is surrounded at home. For many of those monarchs who have escaped from the hands of their enemies, have not escaped the conspiracies of their own body-guards.
And kings have of necessity as many causes of sadness as there are waves on the ocean. But if monarchy is unable to render life devoid of grief, then what else can possibly achieve this? Nothing, indeed, of this life; but this saying of Paul alone, brief and simple as it is, will of itself open to us this treasure.
