Husserl's Ideas for a Pure Phenomenology and Phenomenological Philosophy (1913) is one of the
key texts of twentieth century philosophy. It is the first of Husserl's published works to
present his distinctive version of transcendental philosophy and to put forward the ambitious
claim that phenomenology is the fundamental science of philosophy. In Ideas Husserl introduces
for the first time the conceptual arsenal of his mature phenomenology: the principle of all
principles the phenomenological epoché and reduction pure consciousness and the noema. All
these difficult notions have been influential and controversial in subsequent philosophy both
analytic and Continental. In this commentary thirteen leading scholars of Husserlian
phenomenology set out to clarify and defend Husserl's views connecting them to the vast corpus
of his published and unpublished writings and discussing the main available interpretations in
the existing scholarship. The result is a detailed and comprehensive account of the most
original form of transcendental philosophy since Kant's Critique of Pure Reason.
