Ideas II has been the source of several issues in the broader phenomenological literature. Some of these issues focus on the particular aims of that work and its place within the system of transcendental constitutive and genetic Phenomenology. Others are concerned with its significance in the development of Husserl's thought on the possibility and direction of a phenomenological philosophy of natural science (still under discussion), along with a systematic phenomenological grounding of the human sciences. Furthermore, the manuscript of Ideas II seems to have contributed to the formation of Heidegger's views on the nature and status of Husserl's Phenomenology and of Phenomenology in general. Thus, an examination of the actual meaning of the analyses in Ideas II would contribute significantly to the understanding of a variety of important issues in phenomenological philosophy.
