על שכל אדם ישר הוא בן חורין כ״בEvery Good Man is Free 22

א׳
1XXII.  [158] Let us then do away with the idle fancy, to which the great mass of men feebly cling, and fixing our affections on that holiest of possessions, truth, refuse to ascribe citizenship or freedom to possessors of so-called civic rights, or slavery to servants, whether homebred or purchased, but dismissing questions of race and certificates of ownership and bodily matters in general, study the nature of the soul. 
ב׳
2[159] For if the soul is driven by desire, or enticed by pleasure, or diverted from its course by fear, or shrunken by grief, or helpless in the grip of anger, it enslaves itself and makes him whose soul it is a slave to a host of masters. But if it vanquishes ignorance with good sense, incontinence with self-control, cowardice with courage and covetousness with justice, it gains not only freedom from slavery but the gift of ruling as well. 
ג׳
3[160] But souls which have as yet got nothing of either kind, neither that which enslaves, nor that which establishes freedom, souls still naked like those of mere infants, must be tended and nursed by instilling first, in place of milk, the soft food of instruction given in the school subjects, later, the harder, stronger meat, which philosophy produces. Reared by these to manhood and robustness, they will reach the happy consummation which Zeno, or rather an oracle higher than Zeno, bids us seek, a life led agreeably to nature.
