In his Ideas Pertaining to a Pure Phenomenology and to a Phenomenological Philosophy, Edmund Husserl introduces the pure 'I' (reines Ich) as a peculiar, non-constituted transcendence that is not contained in the stream of immanent experience. In the Ideas, however, Husserl does not elaborate much on the consequences of this step regarding the internal time-consciousness.
In this text, using Husserl's analyses in his so-called L-Manuscripts, we are trying to analyze the specific way of being of this pure 'I' in the light of this problem.
