This volume collects papers that were presented at the 34th International Ludwig Wittgenstein Symposium 2011 in Kirchberg am Wechsel, Austria. They focus on five key debates in contemporary epistemology: Does the term "to know" vary its meaning according to features of the contexts in which it is uttered? What role may "epistemic virtues" play in our cognitive activities? What is the surplus value of having knowledge instead of mere true belief? What is the structure and significance of testimonial knowledge and belief? And when is disagreement rational, especially if it occurs among "epistemic peers"? In addition, a section is devoted to novel discussions of the work of Wittgenstein. Papers by A. Beckermann, E. Brendel, W. Davis, C. Elgin, S. Goldberg, J. Greco, A. Kemmerling, H. Kornblith, M. Solomon, M. Williams, and many others.ams, and many others.
