In the Wealth of Nations, Adam Smith argued that the “propensity to truck, barter, and exchange” was inherent in human nature. But in the following passage, Jean Baptiste Say offers a more viceral explanation for trade. The urge to sell being less about human nature and perhaps more about the call of nature.

An immutable law of motion as old as the market, that compels a producer to no less dispatch products, services and even money that are useless to the producer to the market, than a bear is compelled by nature to dispatch its sh#t to the woods. And, most likely governed by the same law of supply. The echo of entropy heard as much in the woods as in the market.
