The only wealth we can possess

Someone has a handsome household and a beautiful house, he sows much and receives much profit: but all this is not his own doing, but rather all around him. Praise that in him which can neither be taken away nor given, which belongs to the person himself.
You ask, what is this? The soul, and in it perfect reason. After all, man is a rational being; therefore, for him, the highest good is to fulfill that for which he was born.
And what does reason require of him? Nothing difficult: only to live according to his nature. This is difficult only because of the universal madness: we all push each other toward vice. How can we return to sanity those who are not restrained by anyone, but driven forward by the whole crowd? Farewell.
