A Theory of Epistemic Justification

This book proposes an original theory of epistemic justification that offers a new way to relate justification to the epistemic goal of truth-conducive belief. The theory is based on a novel analysis of reliable belief-formation that answers classic objections to reliability theories in epistemology. The analysis generates a way of distinguishing justified belief from believing justifiedly, such that inerrant belief-formation need not be justificatory whereas systemic deception could be. It thereby respects the intuition that standards for justification must be accessible to the believer, while maintaining the essential connection of justification to truth.

The analysis shows how justification relates to, but is distinct from, evidence, rationality, and probability. It provides a unifying treatment of issues central to current debate in epistemology, including epistemic paradoxes, epistemic closure, skepticism, contextualism, virtue theories, the effect of luck on knowledge and justification, the interpretation of subjunctive conditions for justification, the conflict between internalism and externalism, and metaphilosophical evaluation of epistemological theories. There are further applications to metaphysics, the philosophy of language, the philosophy of science, and ethics.

The book will engage philosophers working in epistemology or related fields, and their graduate students.
