I’m asked from time to time which undergraduate courses best prepared me for working at Goldman Sachs and in the government. People assume I’ll list courses in economics or finance, but I always answer that the key was Professor Demos’s philosophy course and the conversations about existentialism in coffee shops around campus.
That’s Robert Rubin, former U.S. Secretary of the Treasury during the Clinton administration and former chair of Goldman Sachs, writing about the influence on him of a philosophy course he took as an undergraduate in 1956, in an essay in The New York Times.
Professor Demos would use Plato and other great philosophers to demonstrate that proving any proposition to be true in the final and ultimate sense was impossible. His approach to critical thinking planted a seed in me that grew during my years at Harvard and throughout my life. The approach appealed to what was probably my natural but latent tendency toward questioning and skepticism.
I concluded that you can’t prove anything in absolute terms, from which I extrapolated that all significant decisions are about probabilities. Internalizing the core tenet of Professor Demos’s teaching—weighing risk and analyzing odds and trade-offs—was central to everything I did professionally in the decades ahead in finance and government.
Rubin also picked up some existentialism from the coffeehouse scene in Cambridge:
At the same time that I was processing Professor Demos’s class, one of the big ideas floating around coffeehouses in Cambridge, Mass., was existential philosophy. In time, I arrived at my own interpretation of that way of thinking. To me, existentialism is an internalized sense of perspective. I came to believe that on one hand, the present matters a great deal, but on the other hand, in the totality of space and time, the here and now becomes insignificant.
The combined influence of Professor Demos’ course and the coffeehouse existentialism had a long lasting therapeutic effect on Rubin: “embracing these two perspectives brought me a sense of calm in what were incredibly stressful situations.”
As for Professor Demos, here is an interesting bit about him from Wikipedia:
According to the recollections of Bertrand Russell, Demos saved up and traveled steerage to the United States specifically to improve his education, having read all the books available to him at home. Arriving in Boston in 1913 without money, he first worked as a waiter in a restaurant and then as a janitor in the Harvard student halls of residence in order to fund his tuition at the university. He studied under Bertrand Russell, who was temporarily at Harvard, and Russell found Demos to be one of his best students and was impressed by his enthusiasm for philosophy which he found refreshing. Demos obtained his PhD in 1916 for a dissertation titled The Definition of Judgment. He was naturalized as an American citizen in 1921.
