This volume presents, for the first time in English, Husserl's seminal 1923/24 lecture course First Philosophy (Erste Philosophie) together with a selection of material from the famous research manuscripts of the same time period. The lecture course is divided into two systematic, yet interrelated parts ("Critical History of Ideas" and "Theory of the Phenomenological Reduction"). It has long been recognized by scholars as among the most important of the many lecture courses he taught in his career. Indeed it was deemed as crucially important by Husserl himself, who composed it with a view toward eventual publication. It is unsurprising, then, that First Philosophy is the only lecture course that is consistently counted among his major works. In addition to furnishing valuable insights into Husserl's understanding of the history of philosophy, First Philosophy is his most sustained treatment of the phenomenological reduction, the central concept of his philosophical methodology. The selection of supplemental texts expands on the topics treated in the lectures, but also add other themes from Husserl's vast oeuvre. The manuscript material is especially worthwhile, because in it, Husserl offers candid self-criticisms of his publicly enunciated words, and also makes forays into areas of his philosophy that he was loath to publicize, lest his words be misunderstood.
