Sen after Putnam

Modern classical economic theory, originally austere and minimalist (as in Sraffa and Neumann), has entered a second, more enriched phase. Inspired by Adam Smith, Amartya Sen has drawn out the moral implications of formal classical models. But Sen remains open to neoclassical attack on the grounds that science must be value free. In his book The Collapse of the Fact/Value Dichotomy and Other Essays , Hilary Putnam rebuts the view that "fact is fact and value is value and never the twain shall meet". This paper explores consequences of this argument for classical theory. It explains the nature and significance of the entanglement of facts, analysis and values; and the impact of this entanglement on the concept of rationality, on capability theory, on the relationship between human needs and Sraffa basics, on Pasinetti's transformational growth, and on Sen's analysis of the disabled and most wretched. Supporting Sen's approach to human development, it opens the possibility of an enriched classical analysis, which can absorb Martha Nussbaum's analysis of tragedy using a logically and morally coherent political economy.
