Contemporary Approaches to the Problem of Cartesian Skepticism. Open Lecture: Does the External World Exist? Part I. Solving or Dissolving the Skeptical Problem

We consider some newcontemporary approaches to solving or dissolving the problem of skepticism regarding the existence of the external world, in particular, disjunctivism, Duncan Pritchard’s biscopic approach and Timothy Williamson’s knowledge first approach. We argue that resolving the skepticalproblem within the framework of epistemological disjunctivism is problematic because it does not take into account the Wittgenstein's notion of a hinge proposition. In fact, a successful approach to the skepticalproblem requires a revision of the metaphysical premises of traditional epistemology, namely the adoption of a non-metaphysical Wittgenstein’s realism. The recently proposed by D. Pritchard within the frame-work of his “biscopic” approach dissolving of the skeptical problem asa pseudo-problem just combines Wittgenstein’s hinge epistemology and epistemological disjunctivism.
