The Crisis was Husserl's last work. It remained unfinished. Nonetheless it is this work which has found more interpreters than any of his other works. For, although it was conceived as an "introduction" to phenomenology — as was also the case with Ideas I, Formal and Transcendental Logic and Cartesian Meditations — the Crisis obviously contains something completely new inasmuch as it documents the often discussed "turn" in Husserl's later philosophy. Although this "turn" evidently cannot mean Husserl's turn away from transcendental phenomenology, his last work is characterized by a thematic treatment of the problems of history and the life-world.
