‘Who is Juan de Mariana’ explained in 8 minutes

Economists’ appreciation for the School of Salamanca, and the contribution that it made to their discipline, has grown in recent years. An economics professor has just released a podcast encapsulating the teachings of its best-known figure, the Jesuit theologian Juan de Mariana – and it takes just eight minutes of your time.

Lucas M. Engelhardt, an associate professor of economics at Kent State University’s Stark Campus, discusses the Spanish thinker’s distinction between rulers and tyrants, the immorality of inflation, and the reason he believed government officials do so poorly when trying to control key aspects of the economy.

“Some, like Jesús Huerta de Soto, have suggested that when you really look at the writings of the Spanish scholastics like Juan de Mariana,” Engelhardt concludes, “one must conclude that the Austrian School was founded ultimately, not in Austria, but in Spain, over 200 years before [Carl] Menger was even born.”
