"Tony Lawson is famous for being the most powerful and effective critic of mainstream economics. His criticism is made more effective by the fact that he has an alternative conception of economics and indeed the rest of the social sciences, a conception deriving from his ontological theorising. This volume gives eleven important writers from a variety of fields and points of view within economics a chance to appraise Lawson's work; and with his replies the reader gets a deeper sense of Lawson's point of view and achievement."John Searle, Slusser Professor of Philosophy, University of California at Berkeley "Over the past 15 years, Tony Lawson's prosecution of a programme to establish a field of social ontology has inspired leading post-positivist economists to think anew about the ends, means, and possibilities of economics as a social science. Much constructive dialogue and debate has been generated and Ontology and Economics chronicles and extends these probing dialogues. Lawson's fans and critics, and first-timers looking for a colourful snapshot of the realist movement in contemporary economics, will find this an immensely rewarding read."Rob Garnett, Texas Christian University, USA"This collection of essays between Tony Lawson and his critics is an important contribution to the ongoing critical discourse on ontology, realism and heterodox economics. While the critics do have their say, Lawson's responses convincingly demonstrate that his project in social ontology not only makes a significant contribution to heterodox economics but also is indispensable for its future development."Frederic S. Lee, Professor of Economics, University of Missouri-Kansas City, USA
