Nor does this take place only with regard to money and food, but every want which is caused by vice and not by necessity is of this nature: however much you supply it with you do not quench it but intensify it. He who restrains himself within the limits prescribed by nature, will not feel poverty; he who exceeds them will always be poor, however great his wealth may be. Even a place of exile suffices to provide one with necessaries; whole kingdoms do not suffice to provide one with superfluities. It is the mind which makes men rich: this it is that accompanies them into exile, and in the most savage wildernesses, after having found sufficient sustenance for the body, enjoys its own overflowing resources: the mind has no more connection with money than the immortal gods have with those things which are so highly valued by untutored intellects, sunk in the bondage of the flesh.
