 According to Stein, nothing in the emergence of an experiential phase is determined. It does not make any phenomenological sense to inquire into determining causes here; experiences simply “flow along” in a “stream of consciousness” and constitute “an undivided and indivisible continuum” (1922: 11[9]). What constitutes their (diachronic and experiential) unity is the “originally generating” or “ultimately constituting” (ursprünglich zeugend, letzt-konstituierend) stream itself (1922: 12[10]). This, in turn, is unified by the irreducible experiential fact that all experiences “emanate from one I” (1922: 15[13]).
