The article discusses how economics has evolved into a separate discipline from other social sciences, but still overlaps with philosophy. The authors explore the connections between economics and philosophy, focusing on questions about the nature of economics as a science, ethics, and the ontology of economics. They highlight the increasing interest in these connections over the past fifty years, with new research networks and journals emerging. The authors published the Elgar Companion to Economics and Philosophy in 2004 to document the current state of these important areas in the philosophy of economics.
