Our contemporary world is host to two coexisting but fundamentally different-and, in at least one crucial respect, contradictory-realities. One of these might be termed Political Reality, though it extends far beyond formal politics and pervades conventional economic thinking. It is the bounded universe of what is acceptable in public economic-social-political discourse. The other is Physical Reality: i.e., what exists in terms of energy and materials, and what is possible given the laws of thermodynamics.
