The pivotal insight that paved Conrad-Martius’ (1880–1966) (CM) way in elucidating the ontological exclusivity of the I, denoted as “I-adhering being” (Ichhaftes Sein), is that despite its peculiarity and incomparability to any other mode of being, only the ontological foundations of the real being in general might enable a faithful comprehension of the I. The phenomenological interpretation suggested in this article presents CM’s ontological understanding of the I vis-a-vis her philosophy of Being, in particular in regard to three of its general characteristics – existence, intelligibility, and self-adherence (Sichheit/Selbsthaftigkeit) – which provide the critical approach to the ontological study of the I. Finally, the understanding of the ontological exclusivity of the I-adhering being is achieved by means of an explication of the joining together of its typical affinities and discrepancies in regard to Being in general.
