[Note 21]: Cf. here the later communication on the pregenital phases of the sexual development, in which this view is confirmed. See below, "Ambivalence."
[Note 22]: Instead of substantiating this statement by many examples I will merely cite Havelock Ellis (The Sexual Impulse, 1903): "All known cases of sadism and masochism, even those cited by v. Krafft-Ebing, always show (as has already been shown by Colin, Scott, and Féré) traces of both groups of manifestations in the same individual."
[Note 23]: On the other hand the restricting forces of the sexual evolution—disgust, shame, morality—must also be looked upon as historic precipitates of the outer inhibitions which the sexual impulse experienced in the psychogenesis of humanity. One can observe that they appear in their time during the development of the individual almost spontaneously at the call of education and influence.
[Note 24]: Studien über Hysterie, 1895, J. Breuer tells of the patient on whom he first practiced the cathartic method: "The sexual factor was surprisingly undeveloped."
[Note 25]: The well-known fancies of perverts which under favorable conditions are changed into contrivances, the delusional fears of paranoiacs which are in a hostile manner projected on others, and the unconscious fancies of hysterics which are discovered in their symptoms by psychoanalysis, agree as to content in the minutest details.
[Note 26]: A psychoneurosis very often associates itself with a manifest inversion in which the heterosexual feeling becomes subjected to complete repression.—It is but just to state that the necessity of a general recognition of the tendency to inversion in psychoneurotics was first imparted to me personally by Wilh. Fliess, of Berlin, after I had myself discovered it in some cases.
[Note 27]: It is not easy to justify here this assumption which was taken from a definite class of neurotic diseases. On the other hand, it would be impossible to assert anything definite concerning the impulses if one did not take the trouble of mentioning these presuppositions.
[Note 28]: One should here think of Moll's assertion, who divides the sexual impulse into the impulses of contrectation and detumescence. Contrectation signifies a desire to touch the skin.
