Phenomenology is one of the most pervasive and influential schools of thought in twentieth-century European philosophy. This book provides a systematic and comprehensive analysis of the idea of the imagination in Husserl and Heidegger. The author also locates phenomenology within the broader context of a philosophical world dominated by Kantian thought, arguing that the location of Husserl within the Kantian landscape is essential to an adequate understanding of phenomenology both as a historical event and as a legacy for present and future philosophy.
