If the _Oedipus Tyrannus_ is capable of moving modern men no less than it moved the contemporary Greeks, the explanation of this fact cannot lie merely in the assumption that the effect of the Greek tragedy is based upon the opposition between fate and human will, but is to be sought in the peculiar nature of the material by which the opposition is shown. There must be a voice within us which is prepared to recognise the compelling power of fate in _Oedipus_, while we justly condemn the situations occurring in _Die Ahnfrau_ or in other tragedies of later date as arbitrary inventions. And there must be a factor corresponding to this inner voice in the story of King Oedipus. His fate moves us only for the reason that it might have been ours, for the oracle has put the same curse upon us before our birth as upon him. Perhaps we are all destined to direct our first sexual impulses towards our mothers, and our first hatred and violent washes towards our fathers; our dreams convince us of it. King Oedipus, who has struck his father Laius dead and has married his mother Jocasta, is nothing but the realised wish of our childhood. But more fortunate than he, we have since succeeded, unless we have become psychoneurotics, in withdrawing our sexual impulses from our mothers and in forgetting our jealousy of our fathers. We recoil from the person for whom this primitive wish has been fulfilled with all the force of the repression which these wishes have suffered within us. By his analysis, showing us the guilt of Oedipus, the poet urges us to recognise our own inner self, in which these impulses, even if suppressed, are still present. The comparison with which the chorus leaves us— “... Behold! this Oedipus, who unravelled the famous riddle and who was a man of eminent virtue; a man who trusted neither to popularity nor to the fortune of his citizens; see how great a storm of adversity hath at last overtaken him” (Act v. sc. 4). This warning applies to ourselves and to our pride, to us, who have grown so wise and so powerful in our own estimation since the years of our childhood. Like Oedipus, we live in ignorance of the wishes that offend morality, wishes which nature has forced upon us, and after the revelation of which we want to avert every glance from the scenes of our childhood. In the very text of Sophocles’ tragedy there is an unmistakable reference to the fact that the Oedipus legend originates in an extremely old dream material, which consists of the painful disturbance of the relation towards one’s parents by means of the first impulses of sexuality. Jocasta comforts Oedipus—who is not yet enlightened, but who has become worried on account of the oracle—by mentioning to him the dream which is dreamt by so many people, though she attaches no significance to it—
