The thesis of this paper is that the debate on realism versus constructivism is misconceived as there exist many different variants of constructivism, each of which operates with a certain, albeit minimalist social ontology. Different concepts of realism are carved out in phenomenology, Berger and Luckmann’s social constructivism, ethnomethodology, relational constructionism, and, finally, communicative constructivism. A differentiated view is recommended.
