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.

This book is a collection of essays in systematic ontology. The parts of its title - "Things" and "Ways They Are" - are indicative of two broadly and intensively discussed issues in current ontology, namely, what categories of entities there are and in what ways they are relevant for our discourses. The three sections of the volume correspond to focuses of ontological research: "Before Ontology" is dedicated to conceptual, methodological, and meta-ontological issues; "Ontology at Work" raises general topics of categorial ontology, and the final section "Ontology in Application" discusses questions such as those relating to free will and our conception of the human being. The book is a tribute to Edmund Runggaldier on the occasion of his 65th birthday. Its seventeen papers are authored by such distinguished scholars as Lynne Rudder Baker, Franz von Kutschera, E. J. Lowe, Otto Muck, Paul Weingartner, Timothy Williamson, and many others.

Otto Muck (*1928) verbindet in seinem Denken analytische Philosophie und Wissenschaftstheorie mit bleibend gultigen Einsichten der aristotelisch-scholastischen und transzendentalphilosophischen Traditionen. Zentral ist dabei eine integrative Konzeption von Metaphysik: Metaphysik erstellt keine Zusatz- oder Alternativtheorien zu anderen Wissenschaften, sondern expliziert den fundamentalen kategorialen Rahmen, in dem speziellere wissenschaftliche Begrifflichkeiten und Theorieansatze konstituiert werden und ihre Problemlosungsfahigkeit entfalten. Die Essays in diesem Band widmen sich auch Mucks Wahrheitsauffassung, der Rolle von Retorsionsargumenten, seiner Konzeption von wissenschaftlichen und weltanschaulichen Erklarungen sowie theologischen Anwendungen seines Denkens. Beitrage von E. Runggaldier, C. Kanzian, H. Weidemann, G. Siegwart, W. Loffler, H.-D. Mutschler und N. Wandinger."
