This article addresses Tuukka Kaidesoja’s critique of the philosophical presuppositions of Roy Bhaskar’s theories of critical realism. The article supports Kaidesoja’s naturalistic approach to the philosophy of the social sciences, including the field of social ontology. The article discusses the specific topics of fallibilism, emergence, and causal powers. I conclude that Kaidesoja’s book is a valuable contribution to current debates over critical realism.
