Abstract

Open peer commentary on the article “Towards a PL-Metaphysics of Perception: In Search of the Metaphysical Roots of Constructivism” by Konrad Werner. Upshot: In his target article, Werner proposes a metaphysical foundation for a radical constructivist epistemology that is nonetheless claimed to reconcile constructivism with some sort of realism. While acknowledging his success in demonstrating that constructivism without an external/internal dualism is suitable for his purposes, I shall argue that rejecting a distinction between epistemological and ontological issues makes it questionable whether PL-metaphysics can make constructivism compatible with realism
