<DIV>Hopkins begins his study with Plato's written and unwritten theories of eid&#234; and Aristotle's criticism of both. He then traces Husserl's early investigations into the formation of mathematical and logical concepts, charting the critical necessity that leads from descriptive psychology to transcendentally pure phenomenology. An investigation of the movement of Husserl's phenomenology of transcendental consciousness to that of monadological intersubjectivity follows. Hopkins then presents the final stage of the development of Husserl's thought, which situates monadological intersubjectivity within the context of the historical a priori constitutive of all meaning. An exposition of the unwarranted historical presuppositions that guide Heidegger's fundamental ontological and Derrida&#8217;s deconstructive criticisms of Husserl&#8217;s transcendental phenomenology concludes the book. By following Husserl's personal trajectory Hopkins is able to show the unity of Husserl's philosophical enterprise, challenging the prevailing view that Husserl&#8217;s late turn to history is inconsistent with his earlier attempts to establish phenomenology as a pure science.
