Economist/finance quant Eric Falkenstein, 51, becomes a Christian (h/t Tyler Cowen).
His essay, much like those by C.S. Lewis, makes sense to the converted. However, despite its title, "An Economist's Rational Road to Christianity", I doubt it will change the views of those who are committed to their unbelief.
The Saul treatment, I guess, is reserved for very special cases.
