When anyone shows himself overly confident in ability to understand and interpret the works of Chrysippus, say to yourself, “Unless Chrysippus had written obscurely, this person would have had no subject for his vanity. But what do I desire? To understand nature and follow her. I ask, then, who interprets her, and, finding Chrysippus does, I have recourse to him. I don’t understand his writings. I seek, therefore, one to interpret them.” So far there is nothing to value myself upon. And when I find an interpreter, what remains is to make use of his instructions. This alone is the valuable thing. But, if I admire nothing but merely the interpretation, what do I become more than a grammarian instead of a philosopher? Except, indeed, that instead of Homer I interpret Chrysippus. When anyone, therefore, desires me to read Chrysippus to him, I rather blush when I cannot show my actions agreeable and consonant to his discourse.
