Against the current: Sraffa's unpublished manuscripts and the history of economic thought *

The paper throws some new light on Sraffa's contribution, using material from his yet unpublished papers. Attention focuses on Sraffa's rediscovery of the distinct character of the classical theory of value and distribution and his refutation of the Marshallian interpretation that it is only a special case of demand and supply theory, his reformulation of the classical theory, and his criticism of the alternative neoclassical theory.
