Karl R. Popper, un filósofo con los pies en el suelo

Abstract

Karl Popper always claimed himself to be a realist. However, his constant denial to give definitions to the philosophical concepts, makes it difficult to understand what exactly he means by realism. This article focuses the attention on three meanings of Popper’s realism: a metaphysical, an epistemological and a sensible real-ism. The later sense can be rooted in the new studies on the ethical roots of all Popper’s philosophy.
