“ Zeno of Citium in his Anecdotes relates that in a fit of heedlessness he sewed a sheepskin to his cloak. He was ugly to look at, and when performing his gymnastic exercises used to be laughed at. He was accustomed to say, raising his hands, "Take heart, Crates, for it is for the good of your eyes and of the rest of your body. 92. You will see these men, who are laughing at you, tortured before long by disease, counting you happy, and reproaching themselves for their sluggishness." He used to say that we should study philosophy to the point of seeing in generals nothing but donkey-drivers. ”
