Damian Byers analyzes the form Husserl gives to the problem of knowledge—the way this form influences the development of the phenomenological method, and the results of its application. In a very clear fashion, Byers presents Husserl’s understanding of the roles of intentionality, idealism, temporalization, and kinesthesia in the constitution of knowledge. Drawing upon all of Husserl’s major texts, he corrects many misapprehensions about Husserl’s doctrines of intentionality and idealism. Byers argues that Husserl’s transcendental phenomenology is both a philosophy of closure and control and a philosophy of openness and vulnerability.
