In Lev Shestov: Existential Philosopher and Religious Thinker, Michael Finkenthal explores the evolution of Lev Shestov’s philosophical and religious intellectual contributions. The hermeneutical effort is mainly based on the Shestovian oeuvre, but his thought is considered in light of existential philosophies in their evolution from Pascal, Nietzsche, and Kierkegaard to those of the twentieth century. Shestov’s «deconstruction» of philosophy is discussed parallel to the analysis of the formation of his religious thought and its relevancy in the context of efforts by Buber, Rosenzweig, and Levinas to redefine Judaism.
