Ferguson:
In my view Paul Krugman has done fundamental damage to the quality of public discourse on economics. He can be forgiven for being wrong, as he frequently is--though he never admits it. He can be forgiven for relentlessly and monotonously politicizing every issue. What is unforgivable is the total absence of civility that characterizes his writing. His inability to debate a question without insulting his opponent suggests some kind of deep insecurity perhaps the result of a childhood trauma. It is a pity that a once talented scholar should demean himself in this way.
