This interdisciplinary collection of essays examines Leo Tolstoy’s unorthodox and provocative approach to spirituality, as presented in his numerous literary and his philosophico-religious works. The collection includes twelve contributions, especially written for this collection, and its contributors are writers, philosophers, literary critics, and experts for Russian literature. Six of the essays examine Tolstoy’s literary works, while the other six scrutinize more closely his philosophical views. The two central foci of examinations of the included essays are The Kreutzer Sonata and The Kingdom of God is within You.
