Essays on Skepticism collects Brueckner's most important work in this area, providing a connected and comprehensive guide to the complex state of play on this intensively studied area of philosophy. The guiding questions of this volume are: Can we have knowledge of the external world of things outside our minds? Can we have knowledge of the internal world of our own contentful mental states? The work divides into four sections: I. Transcendental Arguments
against Skepticism; II. Semantic Answers to Skepticism; III. Self-knowledge; IV. Skepticism and Epistemic Closure.
