psychic pleasure, and only the excess remains in consciousness as psychic lust. This also undergoes an increase, since, either through reflex spinal influence or through a peculiar coloring in the sensorium of sensory impressions, a kind of hallucination of bodily pleasure takes place, with a vague localization of the objectively projected sensation. In the self-torture of religious enthusiasts (fakirs, howling dervishes, religious flagellants) there is an analogous state, only with a difference in the quality of pleasurable feeling. Here the conception of martyrdom is also apperceived without its pain, for consciousness is filled with the pleasurably colored idea of serving God, atoning for sins, deserving Heaven, etc., through martyrdom." This statement cannot be said to clear up the matter entirely; but it is fairly evident that, when a woman says that she finds pleasure in the pain inflicted by a lover, she means that under the special circumstances she finds pleasure in treatment which would at other times be felt as pain, or else that the slight real pain experienced is so quickly followed by overwhelming pleasure that in memory the pain itself seems to have been pleasure and may even be regarded as the symbol of pleasure. There is a special peculiarity of physical pain, which may be well borne in mind in considering the phenomena now before us, for it helps to account for the tolerance with which the idea of pain is regarded. I refer to the great ease with which physical pain is forgotten, a fact well known to all mothers, or to all who have been present at the birth of a child. As Professor von Tschisch points out ("Der Schmerz," _Zeitschrift für Psychologie und Physiologie der Sinnesorgane_, Bd. xxvi, ht. 1 and 2, 1901), memory can only preserve impressions as a whole; physical pain consists of a sensation and of a feeling. But memory cannot easily reproduce the definite sensation of the pain, and thus the whole memory is disintegrated and speedily forgotten. It is quite otherwise with moral suffering, which persists in memory and has far more influence on conduct. No one wishes to suffer moral pain or has any pleasure even in the idea of suffering it.
