How long are ye poor and needy? It is not possible for him to be rich, who is not wealthy in his soul; like as it is not possible for him to be poor, who hath not the poverty in his mind. For if the soul is a nobler thing than the body, the less noble parts have not power to affect it after themselves; but the noble part draws over unto herself, and changes those that are not so noble. For so the heart, when it has received any hurt, affects the whole body accordingly; if its temperament be disordered, it mars all, if it be rightly tempered, it profits all. And if any of the remaining parts should have become corrupt, while this remains sound, it easily shakes off what is evil in them also.
