The inertia of the human mind and its resistance to innovation are most clearly demonstrated not, as one might suspect, by the ignorant mass - which is easily swayed once its imagination is caught - but by professionals with a vested interest in tradition and in the monopoly of learning. Innovation is a two-fold threat to academic mediocrities; it endangers their oracular authority, and it evokes the deeper fear that their whole laboriously constructed intellectual edifice may collapse.
