Paul Krugman will never surrender. He insists that the economic theory does give a good explanation of the current economic trajectory. However, a half of economic profession does not support him (and the other half). When I and many other scientists working in physics) deny the economic theory this is a "denial of economics". When Krugman denies our denial - this is a denial of denial. When the other half of economists deny Krugman's opinion - this is a denial of denial of denial of economics. They do not deny economics as we do.
