Eugen Fink's Sixth Cartesian Meditation, accompanied by Edmund Husserl's detailed and extensive notations, is a pivotal document in the development of one of the dominant philosophical directions of the twentieth century, Husserlian transcendental phenomenology. Meant to follow a systematic revision of Husserl's first five Cartesian Meditations, the Sixth Meditation, written in 1932, constituted a dialogue between Husserl and Fink on the basic principles of phenomenology and on its theoretical limits. The resulting text provides a framework for a radical reinterpretation of phenomenology. Ronald Bruzina's meticulous translation and substantial introduction, detailing the history and importance of the text, make this first English-language edition of Sixth Cartesian Meditation essential reading for students of twentieth-century thought.
