Would you venture to say that, in this universe, this thing or the other thing is an evil, whose origin and cause you are unable to explain and to analyze? And because it interferes with your lawful, perhaps even your unlawful pleasures, would you say that it is pernicious and adverse? What, then, because cold is disagreeable to your members, and is wont to chill the warmth of your blood, ought not winter on that account to exist in the world? And because you are unable to endure the hottest rays of the sun, is summer to be removed from the year, and a different course of nature to be instituted under different laws? Hellebore is poison to men; should it therefore not grow? The wolf lies in wait by the sheepfolds; is nature at all in fault, because she has produced a beast most dangerous to sheep? The serpent by his bite takes away life; a reproach, forsooth, to creation, because it has added to animals monsters so cruel.
It is rather presumptuous, when you are not your own master, even when you are the property of another, to dictate terms to those more powerful; to wish that that should happen which you desire, not that which you have found fixed in things by their original constitution. Wherefore, if you wish that your complaints should have a basis, you must first inform us whence you are, or who you are; whether the world was created and fashioned for you, or whether you came into it as sojourners from other regions. And since it is not in your power to say or to explain for what purpose you live beneath this vault of heaven, cease to believe that anything belongs to you; since those things which take place are not brought about in favour of a part, but have regard to the interest of the whole.
