When someone himself on act of his powers of understanding and expounding the writings Chrysippus, then say to yourself, If Chrysippus had not written obscurely, this man would have nothing whereon to exalt himself. But I, what do I desire? Is it not to learn to understand Nature and to follow her? I inquire, then, who can expound Nature to me and hearing that Chrysippus can, I betake myself to him. But I do not understand his writings, therefore I seek an expounder for them. And so far there is nothing exalted. But when I have found the expounder, it remains for me to put into practice what he declares to me; and in this alone is there anything exalted. But if I look on the exposition as a thing to be admired in itself, what else am I become than a grammarian instead of a sage? except that the exposition is not of Homer but of Chrysippus. Therefore when one may ask me to lecture on the philosophy of Chrysippus, I shall rather blush when I am not able to show forth works of a like nature and in harmony with the words.
