Knowledge and its Limits at 20

NEW! Knowledge and its Limits at 20 Conference to be held online and at the University of Geneva, Switzerland, 5-6 November 2020.

Invited speakers: Jessica Brown (St Andrews), Pascal Engel (EHESS, Paris), Anne Meylan (Zurich), Jennifer Nagel (Toronto), Johannes Roessler (Warwick), Timothy Williamson (Oxford).

Timothy Williamson's Knowledge and its Limits has a good claim to being the most influential monograph in contemporary epistemology. Knowledge and its Limits is a major source of current debates about the nature and norms of assertion and belief, the difficulties attending the analysis of knowledge as justified true belief, and the anti-luminosity of knowledge, and has inspired many to pursue a knowledge-centered approach to such issues as confirmation, evidence, and justification. Williamson's "knowledge-first" program has been widely debated and even its staunchest opponents admit that it is a force to be reckoned with in the contemporary epistemological landscape.

The twentieth anniversary of the publication of Knowledge and its Limits seems a perfect occasion to assess the book’s contribution and the research program it generated with a degree of hindsight and to evaluate the implications of the knowledge-first approach in areas beyond epistemology such as the philosophy of mind and philosophy of action. This is the rationale behind the international conference Knowledge and its Limits at 20 (Geneva, 5-6 November 2020). We hope that it will provide a comprehensive assessment of the knowledge-first approach, as well as opening up new perspectives on its implications both inside and outside epistemology.
