Veblen, Marshall and neoclassical economics

Alfred Marshall is often depicted as a pioneer of neoclassical economics almost as if this is a label he embraces and promotes. Yet neoclassical economics is not a category Marshall deploys but a term Thorstein Veblen introduces in characterising Marshall. Veblen coins the term neoclassical to identify an ontological discrepancy in the work of a specific group of his contemporaries, a prominent figure among whom is Marshall. Veblen's view is that Marshall and other neoclassicals discern features of social reality that suggest a tentative recognition of a causal processual social ontology of the type Veblen associates with modern evolutionary approaches and yet also remain staunchly committed to a taxonomic conception of science underpinned by a quite different set of ontological presuppositions. Veblen's assessment of Marshall is brief and assertive. In this paper it is argued that the ontological discrepancy interpretation of Marshall, that Veblen first sketched, can convincingly be filled out, has substantial merit and is of importance in developing an adequate appreciation of Marshall.
