Book X · Chapter 2

Observe what thy nature requires, so far as thou art governed by nature only: then do it and accept it, if thy nature, so far as thou art a living being, shall not be made worse by it. And next thou must observe what thy nature requires so far as thou art a living being. And all this thou mayst allow thyself, if thy nature, so far as thou art a rational animal, shall not be made worse by it. But the rational animal is consequently also a political [social] animal. Use these rules, then, and trouble thyself about nothing else.
