Open peer commentary on the target article “Arguments Opposing the Radicalism of Radical Constructivism” by Gernot Saalmann. First paragraph: Although supportive of many of the positions taken by constructivists, pragmatists, and instrumentalists against “metaphysical realism,” the author Gernot Saalmann mounts arguments against all epistemological radicalisms, in favor of a critical realism. Ultimately he seeks “development of an antimetaphysical, non-objectivist epistemology” rooted in pragmatism.
