Book X · 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.
Observe what thy nature asks of thee, as one controlled by Nature alone, then do this and with a good grace, if thy nature as a living creature is not to be made worse thereby. Next must thou observe what thy nature as a living creature asks of thee. And this must thou wholly accept, if thy nature as a rational living creature be not made worse thereby. Now the rational is indisputably also the civic. Comply with these rules then and be not needlessly busy about anything.
