What difference does it make how much there is laid away in a man's safe or in his barns, how many head of stock he grazes or how much capital he puts out at interest, if he is always after what is another's and only counts what he has yet to get, never what he has already. You ask what is the proper limit to a person's wealth? First, having what is essential, and second, having what is enough.
Seneca the YoungerThe wise man will not pardon any crime that ought to be punished, but he will accomplish, in a nobler way, all that is sought in pardoning. He will spare some and watch over some, because of their youth, and others on account of their ignorance. His clemency will not fall short of justice, but will fulfill it perfectly.
