 * Things which bestow upon the soul no greatness or confidence or freedom from care are not goods. But riches and health and similar conditions do none of these things; therefore, riches and health are not goods. Things which bestow upon the soul no greatness or confidence or freedom from care, but on the other hand create in it arrogance, vanity, and insolence, are evils. But things which are the gift of Fortune drive us into these evil ways. Therefore these things are not goods.
 * As quoted in Epistulae morales ad Lucilium by Seneca, Epistle LXXXVII (trans. R. M. Gummere)
