In Part IV we are transferred to the year A.D. 3000. An Elderly Gentleman, attired in very pronounced fashions that have not changed from our day, comes from Bagdad, now the British capital--London being only a park and cities being for the most part abolished. He is an amateur student of history and comes to revisit the home of his remote ancestors but finds it now tenanted only by long-livers who regard him as a child and chaperone and instruct him as such. At first he loquaciously vents his own opinions on a great variety of subjects with the utmost confidence but finally, under the tutelage of a Primary and a Secondary, and at last from contact with an awful Tertiary (for thus those in the first, second, and third century of their lives are known and labeled) he loses confidence, becomes more and more depressed at finding so many things he cannot understand, and has a serious attack of the “discouragement” that is generally the doom of all short-livers who visit these parts. In the end the aged Briton is so confounded by the wisdom that he cannot comprehend that life loses all its attractions and he finally dies of exhaustion at the feet of the Oracle. Napoleon also swaggers and boasts upon the stage, but his ideals, too, are shown to be only characteristic of the short-livers and he is completely subjected. Part V of this Pentateuch is dated A.D. 31,920. Children are now born from eggs, clamoring to get out when about as mature as our youth are at seventeen, so that there are no children in our sense. They are grown-ups, according to our standard, at three or four. Art and science, after incredible labors, are at last able to produce two homunculi, a male and a female. They represent the consummation of circumstantial or mechanical evolution. They appear, talk, will, feel, apparently not as the reflex mechanisms and automata they are but as completely human. They have, however, almost incredible powers of destruction which they turn first against their own fabricator. So dangerous are they that they have to be destroyed because not truly human since they lack the creative urge from within.
