After having now carried out the new method of the transcendental reduction in its entirety and after having constructed it itself in a methodological ascent from its lower stratum of a merely phenomenological-psychological reduction, we may well say that it has enriched us enormously in this methodological grounding.

Through the starting point of the non-existence of the experienced world it led our considerations to subjectivity, but only as experiencing and thereby as unaffected by this non-existence.
