Polanyi analyzes the historical deployment of a "formal" economic science starting from the "market-scarcity-instrumental rationality triptych." This triptych, and the knowledge associated with it, is shown to be more than merely a "substantial" economic science’s interest in the triptych "need-nature-institution." While we must agree with Polanyi that economism is ill-suited to the first triptych, we hesitate to accept his suggested alternative, a heterogeneous mixture of naturalism and institutionalism, essentialism and historicism.
