The article discusses Imre Lakatos' request for a paper on the Keynesian revolution in economics, aimed at a non-expert audience. The author was asked to consider whether this revolution could be seen as a Kuhnian shift or a move between Lakatosian research programs. Lakatos believed it was time for philosophers of science to study the evolution of social sciences, with economists providing case studies. The lack of such studies leaves uncertainty about what can be learned from the 'Growth of Knowledge' literature.
