EPICTETUS. DISCOURSES. Book iii. §10. ¶1.
WHAT, then, ought each of us to say upon every difficult occasion? "It was for this that I exercised, it was for this that I prepared myself." God says to you, Give me a proof if you have gone through the preparatory combats, according to rule; if you have followed a proper diet, a proper exercise; if you have obeyed your master; and after this, do you faint at the very time of action? Now is the proper time for a fever—bear it well; for thirst, bear it well; for hunger, bear it well. Is it not in your power? Who shall restrain you? A physician may restrain you from drinking, but he cannot restrain you from bearing your thirst well. He may restrain you from eating, but he cannot restrain you from bearing hunger well.—But I cannot follow my studies.—And for what end do you follow them, wretch? Is it not that you may be prosperous? That you may be constant? That you may think and act conformably to nature? What restrains you, but that in a fever you may preserve your ruling faculty conformable to nature? Here is the proof of the matter. Here is the trial of the philosopher; for a fever is a part of life, just as a walk, a voyage, or a journey.
