The voice of the intellect is a soft one, but it does not rest until it has gained a hearing. Ultimately, after endlessly repeated rebuffs, it succeeds. This is one of the few points in which it may be optimistic about the future of mankind, but in itself it signifies not a little.

"We can postulate that there must be diseases founded on a conflict between ego and super-ego. Analysis gives us the right to infer that melancholia is the model of this group, and then we should put in a claim for the name of "narcissistic psychoneuroses" for these disorders."

It sounds like a fairy-tale, but not only that; this story of what man by his science and practical inventions has achieved on this earth, where he first appeared as a weakly member of the animal kingdom, and on which each individual of his species must ever again appear as a helpless infant... is a direct fulfilment of all, or of most, of the dearest wishes in his fairy-tales. All these possessions he has acquired through culture. Long ago he formed an ideal conception of omnipotence and omniscience which he embodied in his gods. Whatever seemed unattainable to his desires - or forbidden to him - he attributed to these gods. One may say, therefore, that these gods were the ideals of his culture. Now he has himself approached very near to realizing this ideal, he has nearly become a god himself. But only, it is true, in the way that ideals are usually realized in the general experience of humanity. Not completely; in some respects not at all, in others only by halves. Man has become a god by means of artificial limbs, so to speak, quite magnificent when equipped with all his accessory organs; but they do not grow on him and they still give him trouble at times... Future ages will produce further great advances in this realm of culture, probably inconceivable now, and will increase man's likeness to a god still more.

Dream's evanescence, the way in which, on awakening, our thoughts thrust it aside as something bizarre, and our reminiscences mutilating or rejecting it — all these and many other problems have for many hundred years demanded answers which up till now could never have been satisfactory.
