text: Therefore, nothing ought to be unexpected by us. Our minds should be sent forward in advance to meet all problems, and we should consider, not what is wont to happen, but what can happen. For what is there in existence that Fortune, when she has so willed, does not drag down from the very height of its prosperity? And what is there that she does not the more violently assail the more brilliantly it shines? What is laborious or difficult for her? She does not always attack in one way, or even with her full strength; at one time she summons our own hands against us; at another time, content with her own powers, she makes use of no agent in devising perils for us. No time is exempt; in the midst of our very pleasures there spring up causes of suffering. War arises in the midst of peace, and that which we depended upon for protection is transformed into a cause of fear; friend becomes enemy, ally becomes foeman. The summer calm is stirred into sudden storms, wilder than the storms of winter. With no foe in sight we are victims of such fates as foes inflict, and if other causes of disaster fail, excessive good fortune finds them for itself. The most temperate are assailed by illness, the strongest by wasting disease, the most innocent by chastisement, the most secluded by the noisy mob.
