@text Amartya Sen - who was awarded the Nobel Prize for Economic Science in 2003 - is one of the leading economists of his generation. He is best known for his deep critique of the liberal and utilitarian inheritances in economics, including the treatment (or neglect) of values and value-judging in public contexts; and his construction of a partial alternative, including entitlements analysis, the capabilities approach and, extending from those two, an integrative development philosophy centered on the direct and instrumental values of freedom and democracy. The important new book provides an exposition and assessment of Amartya Sen's socio-economics, both positive and especially normative, including his contributions to welfare economics, ethics and the theory-and-policy approach of 'human development'. The exposition and assessment will include discussion of the historical and intellectual contexts. The book also analyzes Sen's contributions to philosophy, the second field in which Sen has published and held appointments.
