The Crisis of European Sciences and Transcendental Phenomenology, Husserl's last great work, is important both for its content and for the influence it has had on other philosophers. In this book, which remained unfinished at his death, Husserl attempts to forge a union between phenomenology and existentialism.

Husserl provides not only a history of philosophy but a philosophy of history. As he says in Part I, "The genuine spiritual struggles of European humanity as such take the form of struggles between the philosophies, that is, between the skeptical philosophies--or nonphilosophies, which retain the word but not the task—and the actual and still vital philosophies. But the vitality of the latter consists in the fact that they are struggling for their true and genuine meaning and thus for the meaning of a genuine humanity."

In Experience and Judgment, Husserl explores the problems of contemporary philosophy of language and the constitution of logical forms. He argues that, even at its most abstract, logic demands an underlying theory of experience. Husserl sketches out a genealogy of logic in three parts: Part I examines prepredicative experience, Part II the structure of predicative thought as such, and Part III the origin of general conceptual thought. This volume provides an articulate restatement of many of the themes of Husserlian phenomenology.
