De Stoicorum repugnantiis

Indeed Antipater, in his writings concerning the difference between Cleanthes and Chrysippus, has related that Zeno and Cleanthes would not be made citizens of Athens, lest they might seem to injure their own countries. I shall not much insist upon it, that, if they did well, Chrysippus acted amiss in suffering himself to be enrolled as a member of that city. But this is very contradictory and absurd, that, removing their persons and their lives so far off amongst strangers, they reserved their names for their countries; which is the same thing as if a man, leaving his wife, and cohabiting and bedding with another, and getting children on her, should yet refuse to contract marriage with the second, lest he might seem to wrong the former.
