Added Adam Smith, the most famous quote in economics. Mar 19, 2008. DOR 07:56, 19 March 2008 (UTC)
- Trade is not something imaginary or descriptive, but something real and profitable.
- Commerce links all mankind in one common brotherhood of mutual dependence and interests.
- No example of a barter economy, pure and simple, has ever been described, let alone the emergence from it of money; all available ethnography suggests that there never has been such a thing."
