Edmund Husserl, perhaps more than any other philosopher captures the spirit and movement of philosophy in the twentieth century. In this thorough historical study of Husserl's phenomenological method, Donn Welton presents a unique interpretation of the development of Husserl's philosophical position against the background of systematic insight into the phenomenon of horizon – perhaps the single most important issue that motivates and guides Husserl's thought. The Other Husserl expands Husserl's introductory static method into a genetic phenomenology, moving through his transformation of phenomenology into transcendental philosophy in his Ideas Toward a Pure Phenomenology and applying them to issues of perception, discourse, culture, and context elaborated in his later Crisis in European Science. This serious reflection on the meaning of phenomenology is the first book in English to outline the full scope of Husserl's phenomenological method and to argue for its cogency.
