Patrick Thaddeus Jackson has called it 'all the rage' in the field. Bob Jessop, Colin Wight, Milja Kurki, Jonathan Joseph and Hidemi Suganami have all published major works on the utility of beginning IR research from a critical realist social ontology—an ontology they all credit Roy Bhaskar with originating. The British ecological economist Clive Spash holds the opinion that critical realism offers a thorough basis—as a philosophy of science—for the theoretical foundation of ecological economics. He therefore uses a critical realist lens for conducting research in (ecological) economics. However, also other scholars base ecological economics on a critical realist foundation, such as Leigh Price from Rhodes University.
