This collection of original essays explores the topic of skeptical invariantism in theory of knowledge. It eschews historical perspectives and focuses on this traditionally underexplored, semantic characterization of skepticism.

The book provides a carefully structured, state-of-the-art overview of skeptical invariantism and offers up new questions and avenues for future research. It treats this semantic form of skepticism as a serious position rather than assuming that skepticism is false and attempting to diagnose where arguments for skepticism go wrong.

The essays take up a wide range of different philosophical perspectives on three key questions in the debate about skeptical invariantism: (1) whether the standards for knowledge vary, (2) how demanding the standards for knowledge are, and (3) whether the kind of evidence, reasons, methods, processes, etc. that we can bring to bear are sufficient to meet those standards.

Skeptical Invariantism Reconsidered will be of interest to scholars and advanced students in epistemology and the philosophy of language. .
