“What are you doing, Avarice? see how many things there are whose price exceeds that of your beloved gold: all those which I have mentioned are more highly esteemed and valued. I now wish to review your wealth, those plates of gold and silver which dazzle our covetousness. By Hercules, the very Earth, while she brings forth upon the surface everything that is of use to us, has buried these, sunk them deep, and rests upon them with her whole weight, regarding them as pernicious substances, and likely to prove the ruin of mankind if brought into the light of day. I see that iron is brought out of the same dark pits as gold and silver, in order that we may lack neither the means nor the reward of murder. Thus far we have dealt with actual substances; but some forms of wealth deceive our eyes and minds alike. I see there letters of credit, promissory notes, and bonds, empty phantoms of property, ghosts of sick Avarice, with which she deceives our minds, which delight in unreal fancies; for what are these things, and what are interest, and account books, and usury, except the names of unnatural developments of human covetousness?
