CARDENAS CASTANEDA, Leonardo. Between Semantics and Metaphysics: Inconsistencies in the Realism of Popper. Prax. filos. [online]. 2011, n.33, pp.83-92. ISSN 0120-4688.

In this essay I will explain my arguments regarding the inconsistencies that I have identified in the scientific realism of Karl Popper. Fundamentally, I believe that in the philosophy of this author there is no coherent definition of the notion of truth in order for it to have a relevant role in realist doctrine. Beyond the fact that Popper is credited for assuming a correspondence theory of truth, in several passages of his work he is skeptical about the labor that is able to reach truth in order to determine the success of science. Furthermore, I propose that Popper has strong leanings toward metaphysical realism, especially towards essentialism, however the way to defend this theory remains obscure because there are sections that oppose it throughout his epistemological project.

Palavras-chave : Popper; realism; correspondence theory of truth; essentialism.
