The product of many years of reflection on phenomenology, this book is a comprehensive and creative introduction to the philosophy of Edmund Husserl. Natanson uses Husserl's later work as a clue to the meaning of his entire intellectual career, showing how his earlier methodological work evolved into the search for transcendental roots and developed into a philosophy of the life-world. Phenomenology, for Natanson, emerges as a philosophy of origin, a transcendental discipline concerned with consciousness, history, and world rather than with introspection and traditional metaphysical warfare.
