The present book is a collection of 9 essays, emerging from a long and intense research collaboration among scholars coming from different backgrounds and traditions. As the book subtitle suggests, these essays focus on the ethical, religious, and political aspects of Wittgenstein's thought, which are illustrated and investigated with reference to their complex interaction with Wittgenstein's philosophical method and his conception of philosophy, on the one hand, and with his conception of language and human agency on the other.
