That the Division of Labour is Limited by the Extent of the Market: Limited opportunity for exchange discourages division of labour. Because "water-carriage" extends the market, division of labour, with its improvements, comes earliest to cities near waterways. Civilization began around the highly navigable Mediterranean Sea...
Of the Origin and Use of Money: With division of labour, the producer of one's own labour can fill only a small part of one's needs. Different commodities have served as a common medium of exchange, but all nations have finally settled on metals, which are durable and divisible, for this purpose. Before coinage, people had to weigh and assay with each exchange, or risk "the grossest frauds and impositions." Thus nations began stamping metal, on one side only, to ascertain purity, or on all sides, to stipulate purity and amount. The quantity of real metal in coins has diminished, due to the "avarice and injustice of princes and sovereign
