illness are, if not entirely wiped out by the amnesia, at least partially obliterated. Without fail important details have disappeared from the general picture of such a recent memory, or are placed by false memories. Indeed it happens almost regularly that just before the completion of an analysis, certain memories of recent experiences suddenly come to light. They had been held back all this time, and had left noticeable gaps in the context. We have pointed out that such a crippling of the ability to recall is characteristic of hysteria. In hysteria symptomatic conditions also arise (hysterical attacks) which need leave no trace in the memory. If these things do not occur in compulsion-neuroses, you are justified in concluding that these amnesias exhibit psychological characteristics of the hysterical change, and not a general trait of the neuroses. The significance of this difference will be more closely limited by the following observations. We have combined two things as the meaning of a symptom, its "whence," on the one hand, and its "whither" or "why," on the other. By these we mean to indicate the impressions and experiences whence the symptom arises, and the purpose the symptom serves. The "whence" of a symptom is traced back to impressions which have come from without, which have therefore necessarily been conscious at some time, but which may have sunk into the unconscious--that is, have been forgotten. The "why" of the symptom, its tendency, is in every case an endopsychic process, developed from within, which may or may not have become conscious at first, but could just as readily never have entered consciousness at all and have been unconscious from its inception. It is, after all, not so very significant that, as happens in the hysterias, amnesia has covered over the "whence" of the symptom, the experience upon which it is based; for it is the "why," the tendency of the symptom, which establishes its dependence on the unconscious, and indeed no less so in the compulsion neuroses than in hysteria. In both cases the "why" may have been unconscious from the very first.
