The Roman statesman/philosopher Seneca wrote:
our forefathers…lived every jot as well as we, when they provided and dressed their own meat with their own hands, lodged upon the ground and were not yet come to the vanity of gold and gems…which may serve to show us, that it is the mind, and not the sum, that makes any person rich… No one can be poor that has enough, nor rich, that covets more than he has.
