Better than any other single work, Daniel enables us to understand the significance of the transition Buber made from his early mysticism to the philosophy of dialogue. The book is written in the form of five dialogues, in each of which Daniel and his friends explore a crucial philosophical problem--the nature of interconnection of unity, creativity, action, form, and realization as these illuminate the relations of man to God and the world. Daniel occupies a central position in Buber's life work.
