Perversions acquired by suggestion or auto-suggestion should be combated by suppression of the depraved examples which cause them, as well as by treatment by suggestion. It is needless to say that sexual perverts should always abstain from alcoholic drinks. FOOTNOTES: [4] English translation by F.J. Rebman: Rebman Co., New York. [5] For further information on this subject see _Marshall's_ "Syphilology and Venereal Disease," (London, Balliere, Tindall & Co.); also _Marshall's_ translation of _Fournier's_ "Treatment and Prophylaxis of Syphilis," (New York: Rebman Co.) [6] _Krafft-Ebing_ describes bestiality (connection with animals) and pederasty under the general term of sodomy, but points out that the original meaning of sodomy used in Genesis (Chapter XIX) signified pederasty, _i.e._, anal coitus between men. CHAPTER IX SUGGESTION IN SEXUAL LIFE--AMOROUS INTOXICATION =Suggestion. Cerebral Activity. Consciousness. Subconsciousness and Amnesia. Auto-suggestion.=--The explanation of the phenomena of hypnotism and suggestion by Liébeault and Bernheim has been a veritable scientific revelation for human psychology. Unfortunately it has remained to a great extent unknown to the public and the majority of medical men and jurists. Even at the present day, this subject is regarded either in the light of magic and occult phenomena, or as being connected with imposture and charlatanism. This results from the incapacity of most men to think in a psychological and philosophical manner, to observe for themselves and to take into account the connection which exists between the mind and cerebral activity. I must point out the common error of many physicians, who do not understand the psychological nature of hypnotism, and who place it, like Dubois, in antinomy with psychotherapy. Hypnotism and suggestion in the waking state are one and the same thing; but what the physicians I have mentioned understand by suggestion in the waking state--psychotherapy, action by will power, etc.--is only a chaos of misapplied terms and psychological phenomena, only half understood by them. Sleep by suggestion is only one of the phenomena of suggestion. I must refer the reader to Bernheim's book on "_La Suggestion et ses Applications à la Thérapeutique_," and to my book on hypnotism ("_Der Hypnotismus und die Suggestive Psychotherapie._" Stuttgart, 1902), for I cannot enter into the details here. I will, however, attempt to make clear the action of suggestion in order to explain its connection with the sexual sensations and sentiments.
