Seneca, On Benefits
3.20.1 (tr. John W. Basore):
It is a mistake for anyone to believe that the condition of slavery penetrates into the whole being of a man. The better part of him is exempt. Only the body is at the mercy and disposition of a master; but the mind is its own master, and is so free and unshackled that not even this prison of the body, in which it is confined, can restrain it from using its own powers, following mighty aims, and escaping into the infinite to keep company with the stars.
errat, si quis existimat servitutem in totum hominem descendere. pars melior eius excepta est. corpora obnoxia sunt et adscripta dominis; mens quidem sui iuris, quae adeo libera et vaga est, ut ne ab hoc quidem carcere, cui inclusa est, teneri queat, quominus impetu suo utatur et ingentia agat et in infinitum comes caelestibus exeat.
