In this paper, I discuss critical realists’ and contemporary sociological pragmatists’ approaches to conceptualizing social mechanisms, which, on my reading, each involve some ambiguities or confusions. I sketch some corrections and clarifications that bring into view ways pragmatism and critical realism might inform each other in a constructive fashion on the question of what social mechanisms are. Finally, I suggest a concept of social mechanisms that is compatible with both critical realist and pragmatist insights, as a starting point from which (...) to launch further conversation. (shrink)
