" Within the bounds of positivity we say and find it obvious that, in my own experience, I experience not only myself but others—in the particular form: experiencing someone else. The indubitable transcendental explication showed us not only that this positive statement is transcendentally legitimate but also that the concretely apprehended transcendental ego (who first becomes aware of himself, with his undetermined horizon, when he effects transcendental reduction) grasps himself in his own primordial being, and likewise (in the form of his transcendental experience of what is alien) grasps others: other transcendental egos, though they are given, not originaliter and in unqualifiedly apodictic evidence, but only in an evidence belonging to ‘external’ experience. ‘In’ myself I experience and know the Other; in me he becomes constituted—appresentatively mirrored, not constituted as the original. Hence it can very well be said, in a broadened sense, that the ego acquires—that I, as the one who meditatingly explicates, acquire by ‘self-explication’ (explication of what I find in myself) every transcendency: as a transcendentally constituted transcendency and not as a transcendency accepted with naive positivity. Thus the illusion vanishes: that everything I, qua transcendental ego, know as existing in consequence of myself, and explicate as constituted in myself, must belong to me as part of my own essence. This is true only of ‘immanent transcendencies’. As a title for the systems of synthetic actuality and potentiality that confer sense and being on me as ego in my own essentialness, constitution signifies constitution of immanent objective actuality.
