"No estarás seguro de tener razón si no entiendes los argumentos contrarios a los tuyos mejor que tus oponentes"

"In 1964 -to the disgust and dismay of most of my academic friends- I served as an economic adviser to Barry Goldwater during his quest for the Presidency. That year also, I was a Visiting Professor at Columbia University. The two together gave me a rare entree into the New York intellectual community. I talked to and argued with groups from academia, from the media, from the financial community, from the foundation world, from you name it. I was appalled at what I found. There was an unbelievable degree of intellectual homogeneity, of acceptance of a standard set of views complete with cliche answers to every objection, of smug self-satisfaction at belonging to an in-group. The closest similar experience I have ever had was at Cambridge, England, and even that was a distant second. The homogeneity and provincialism of the New York intellectual community made them pushovers in discussions about Goldwater's views. They had cliche answers but only to their self-created straw-men. To exaggerate only slightly, they had never talked to anyone who really believed, and had thought deeply about, views drastically different from their own. As a result, when they heard real arguments instead of caricatures, they had no answers, only amazement that such views could be expressed by someone who had the external characteristics of being a member of the intellectual community, and that such views could be defended with apparent cogency. Never have I been more impressed with the advice I once received: "You cannot be sure that you are right unless you understand the arguments against your views better than your opponents do." | MILTON FRIEDMAN - "Schools at Chicago" 1974
