Recent pleas for more heterodoxy in explaining economic action have been defending a pluralism for economics. In this article, I analyse these defences by scrutinizing the pluralistic qualities in the work of one of the major voices of heterodoxy, Tony Lawson. This scrutiny will focus on Lawson's alternatives concerning ontology and explanation to mainstream economics. Subsequently, I will raise some doubts about Lawson's pluralism, and identify questions that will have to be addressed by heterodox economists in order to maintain the (...) claim of pluralism.

Realist evaluation has gained prominence in the field of evaluation in recent years. Its theory-driven approach to explaining how and why programmes work or not makes it attractive to many novices, early career researchers, and organizations implementing various programmes globally and relevant to policymakers and programme implementers. While realist evaluation seeks to be pragmatic, adopting principles and methods that can be used to help focus an evaluation, its deep ontological and epistemological foundations make its application in real-life situations challenging. In (...) this paper, we seek to unpack the key tenets scaffolding the practical application of realist evaluation. Although Pawson and Tilley foreground realist evaluation in applied scientific realism, we argue that an amalgam of scientific and critical realist principles underpins realist evaluation. We unpack these principles and illustrate how they fit into each other to provide a cogent theoretical foundation for realist evaluation. (shrink)

Le modèle déductivo-nomologique domine depuis longtemps la réflexion philosophique concernant l’explication en science économique. Or, pour plusieurs, comme James Woodward et Tony Lawson, ce modèle ne considère pas suffisamment la causalité dans l’explication. L’objectif de cet article est double : 1- renforcer la critique que Tony Lawson adresse à l’économie contemporaine et 2- évaluer la théorie alternative qu’il propose, le « réalisme critique », qui tente de réintroduire la causalité dans l’explication en science économique. Nous conclurons que les considérations causales (...) sont très importantes pour l’explication en science économique mais aussi pour bien comprendre les limites de cette science. (shrink)

Recent developments in themethodology of economics have drawn uponpragmatist and realist philosophies of socialscience. These recent developments areoutlined. It is argued that a specific variantof realist philosophy known as critical realismcan provide the basis for a prescriptiveeconomic methodology that is not susceptible topragmatist criticisms.
