I did not meet many of the postwar great thinkers of classical liberalism. There are two exceptions. In 2005 I had a chat with James Buchanan to ask him if I could translate the talk he gave to an audience of graduate students at the IHS summer seminar at the University of Virginia at Charlottesville. He agreed and I translated and published his ideas on ‘the soul of classical liberalism’ in a Dutch liberal periodical.

The other exception is Julian Simon. Perhaps not in the same league as Buchanan, he was certainly a maverick thinker and a classical liberal great. A navy officer, business man, and advertising expert who turned to academia, he is known, to name just a few, for his arguments in the field of population growth, immigration studies and of course the book The Ultimate Resource. In it he argues that all raw materials become cheaper, while humans are the ultimate resource, among many other issues. He also won a famous wager with his critic Paul Ehrlich, stating that the prices of the raw materials Ehrlich could choose (in fact copper, chromium, nickel, tin, tungsten) would decrease (inflation adjusted) over the period of a decade they agreed upon. But that is just the tip of iceberg of this most interesting man. You should really read his autobiography A Life Against the Grain, whenever you have the chance.

In 1995 a friend of mine and I founded the Dutch Benedictus de Spinoza Foundation, meant to group young people educated in (classical) liberalism. In our first public Spinoza-lecture in 1996 Simon agreed to be the speaker. If memory serves right he was on his way to or from a Mont Pelerin Society meeting in Vienna, and was willing to make a small detour. We spent two full days with him, touring The Hague, arranging an interview in a national paper, have a formal dinner with Simon as gues of honor and speaker, and so forth. He was the most congenial guest one can wish. He clearly did not want to be among the hot shots only. In fact he insisted that we should visit ‘the worst neighborhood of the city’. So we went to one of the poorest parts in town, which he found delightful, not because of the (relative) poverty, but because of the multicultural experience and multicultural food at the market.  An other remarkable feature was that in the half hour before we opened the lecture hall, he wished to take a nap on the floor right there!

In his autobiography he is open about his many rejected papers throughout his career, and the way he described how difficult it is to convince academic colleagues of a point that goes against conventional wisdom. No matter how strong the counter-evidence, people will choose to ignore the new facts or insights and keep the author out of the inner circle for as long as possible. I must say it sounds familiar to me, as an author who has attempted to change the views of (classical) liberals and IR theorists on international relations and (classical) liberalism. Even the obvious fact that trade cannot possibly foster peace seems impossible to establish. Alas, reading Simon one also learns to never give up, the truth shall be told, although there is no guarantee of success!
