Note 152 — Chapter IV · SPACE AND TIME

So the events of my dreams, though not occupying any place in the temporal series of the events of waking life, are so far logically connected with that series as both sets of events stand in relation to certain identical elements of psychical temperament and disposition. Another interesting case is that of so-called “dual personality.” The experience of both the two alternating personalities can be arranged in a single temporal series only because of the way in which both sets are inwoven with the systematic interests of other men, whose personality does not alternate, or alternates with a different rhythm. If all mankind were subject to simultaneous alternations of personality, the construction of a single time-series for all our experiences would be impossible. In this discussion I have throughout followed the full and thorough treatment of the problem by Mr. Bradley, Appearance and Reality, chap. 18.
