Falkenblog: An Economist’s Rational Road to Christianity

“A Christian purpose aligns with our nature so well that it is useful to believe and behave “as if” it were true, and in the history of science, many assumptions that were chosen because they worked were later found to be true. Thus, assumptions often are used as contrivances, what Milton Friedman called “as if” assumptions that are not necessarily true, but just good working assumptions. For example, if you assume that individuals are self-interested you can explain many things that are otherwise difficult to explain. When Adam Smith introduced this in 1776, it seemed almost Machiavellian, but it turned out to be a better first-order approximation of individual motivation than any other. It is a miracle that Christianity promotes a societal arrangement as counterintuitive as the free market a couple thousand years before theory and data made this clear.”
