"Stimulating, provocative, often infuriating, but well worth reading."--Peter Newman, "Economica"

"His critical blast blows like a north wind against the more pretentious erections of modern economics. It is however a healthy and invigorating blast, without malice and with a sincere regard for scientific objectivity."--K.E. Boulding, "Political Science Quarterly"

"Certainly one of the most engrossing volumes that has appeared recently in economic theory."--William J. Baumol, "Review of Economics and Statistics"
