"The idea that the "I" is more than just the present experience but something that can, as one and the same, have various experiences and could have other experiences, without this sameness being reducible to anything else (e.g. to any inter-experiential relations), has its root in the fact that every experience in its mere being-experienced essentially already implies a synchronic and diachronic transcendence of "me" qua consciousness with regard to this experience, a transcendence in which the being-experienced of the experience itself consists."
