Introduction

Abstract

Raimo Tuomela (1940-2020) was a leading figure within social philosophy and a pioneer of contemporary social ontology. His main research and publications helped define the scholarly agenda of a philosophical investigation of social reality. Working first on (social) scientific realism and (social) action theory, he then developed an unprecedented account of collective intentionality—the kind of intentionality that individual agents require in order for them to perform intentional actions together, as a group.
