These facts seem to me reducible to a single explanation. There are in every man latent tendencies, which may remain latent throughout his life, but may also be awakened and revealed by some accidental occurrence. They might be called hereditary, since they are found in an inherited organism; but it would be quite as correct to call them innate. In any case, it is very difficult to prove that they are a survival, and above all a resurrection of once existing tendencies. 2. Personal unconsciousness arising from cœnæsthesia, _i.e._, from the internal sensations collectively. This imperceptibly brings us down to consciousness, from the moment when the affective state can be verified without induction. A certain disposition, a certain manner of feeling, is the direct and immediate cause of association. It is permanent or transitory. If permanent, it answers to the temperament or disposition. As the subject is cheerful, melancholy, erotic, or ambitious, an unconscious selection is exercised on the ideas arising in consciousness; an artist and a practical man, in face of the same object, have two totally distinct modes of association. If transitory, it corresponds, in the same individual, to states of health and sickness, to changes of age; each one of these distinct states produces a distinct selection. The unity of certain dreams, in spite of the apparent difference of associations, has its easily discovered cause in an organic or affective disposition—fatigue, depression, oppression, circulatory or digestive troubles, sexual excitement. The simplicity and frequency of these facts will permit us to dispense with insisting upon them. 3. Personal unconsciousness, a residuum of affective states connected with anterior perceptions, or with events of our life. This emotional residuum, although latent, is no less active, and can be recovered by analysis. This case, one of the most important connected with our subject, has recently been studied by Lehmann[115] under the name of displacement (_Verschiebung_) of the sentiments, and by Sully under the name of _transference_ of feelings; this second denomination seems to me the clearer and more accurate of the two. ----- Footnote 115: _Hauptgesetze_, etc., pp. 268, 250-357; Sully, _The Human Mind_, ii. 78; cf. _Outlines of Psychology_, p. 349. -----
