You can imagine how rapidly I am reviewing a great number of conditions which are associated with the Oedipus-complex, of practical as well as of theoretical importance. I cannot enter upon their variations or possible inversions. Of its less immediate relations I only wish to indicate the influence which the Oedipus-complex has been found to exert on literary production. In a valuable book, Otto Rank has shown that the dramatists of all times have taken their materials principally from the Oedipus-and incest-complexes, with their variations and disguises. Moreover, we will not forget to mention that the two guilty wishes of Oedipus were recognized long before the time of psychoanalysis as the true representatives of the unrestrained life of impulses. Among the writings of the encyclopedist Diderot we find a famous dialogue, _The Nephew of Ramau_, which no less a person than Goethe has translated into German. In this you may read the remarkable sentence: "_If the little savage were left to himself he would preserve all his imbecility, he would unite the passions of a man of thirty to the unreasonableness of the child in the cradle; he would twist his father's neck and bed with his mother_." There is also one other thing of which I must needs speak. The mother-wife of Oedipus shall not have reminded us of the dream in vain. Do you still remember the result of our dream analysis, that the wishes out of which the dream is constructed so frequently are of a perverse, incestuous nature, or disclose an enmity toward near and beloved relatives the existence of which had never been suspected? At the time we did not trace the sources of these evil impulses. Now you may see them for yourselves. They represent the disposition made in early infancy of the libidinous energy, with the objects, long since given up in conscious life, to which it had once clung, which are now shown at night to be still present and in a certain sense capable of activity. But since all people have such perverse, incestuous and murderous dreams, and not the neurotics alone, we may conclude that even those who are normal have passed through the same evolutionary development, through the perversions and the direction of the libidio toward the objects of the Oedipus-complex. This, then, is the way of normal development, upon which the neurotics merely enlarge. They show in cruder form what dream analysis exposes in the healthy dreamer as well. Accordingly here is one of the motives which led us to deal with the study of the dream before we considered the neurotic symptom. TWENTY-SECOND LECTURE GENERAL THEORY OF THE NEUROSES _Theories of Development and Regression--Etiology_ We have learned that the libidio goes through an extensive development before it can enter the service of reproduction in a way which may be regarded as normal. Now I wish to present to you what importance this fact possesses for the causation of neuroses.
