Diedre McCloskey

"If he is a passionate man he knows passionately that his theory is the correct one; if a sober man he knows it soberly; anyway he knows it. For some reason, however, and despite his writing or talking, he cannot persuade all of his colleagues. The question arises, why?" --Deidre (Donald) N. McCloskey
