Today considered a landmark of twentieth-century intellectual history, I and Thou is also one of the most important books of Western theology. In it, Martin Buber, heavily influenced by the writings of Frederich Nietzsche, united the proto-Existentialists currents of modern German thought with the Judeo-Christian tradition, powerfully updating faith for modern times. Since its first appearance in German in 1923, this slender volume has become one of the epoch-making works of our time. Not only does it present the best thinking of one of the greatest Jewish minds in centuries, but has helped to mold approaches to reconciling God with the workings of the modern world and the consciousness of its inhabitants.
