This paper discusses important aspects of Husserl’s phenomenology that were not fully understood until his unpublished manuscripts were studied. The topics covered include the analysis of the constituting corporeal subjectivity, conditions for representifications, I-consciousness, transcendental subjectivity as intersubjectivity, development of phenomenological philosophy, and Husserl’s metaphysics. The findings shed light on Husserl’s deep insights into the nature of consciousness and subjectivity, expanding our understanding of his philosophical contributions.
