What does it mean to think of philosophy in the condition of modernism, in which its relation to its past and future has become a relevant problem? This book argues that the writings of Wittgenstein, Heidegger, and Kierkegaard are best understood as responsive (each in their own way) to such questions. Through detailed analysis of these authors' most influential texts, Stephen Mulhall reorients our sense of the philosophical work each text aims to accomplish, engendering a critical dialogue between them from which the elements of a new conception of philosophy might emerge.
