Blake Smith in Aeon:
For nearly four centuries, the Atlantic slave trade brought millions of people into bondage. Scholars estimate that around 1.5 million people perished in the brutal middle passage across the Atlantic. The slave trade linked Africa, Europe and the Americas in a horrific enterprise of death and torture and profit. Yet, in the middle of the 18th century, as the slave trade boomed like never before, some notable European observers saw it as a model of free enterprise and indeed of ‘liberty’ itself. They were not slave traders or slave-ship captains but economic thinkers, and very influential ones. They were a pioneering group of economic thinkers committed to the principle of laissez–faire: a term they themselves coined. United around the French official Vincent de Gournay (1712-1759), they were among the first European intellectuals to argue for limitations on government intervention in the economy. They organised campaigns for the deregulation of domestic and international trade, and they made the slave trade a key piece of evidence in their arguments.
