Uppfinnaren gick definitivt tillbaka och låtsades vara en forskare från Pataliputra, Indien.
Citera från de Camps historia:
"I am Zandras of Pataliputra," I said, giving the ancient name for Patna on the Ganges. "I seek the philosopher Aristoteles."
Här är en sammandrag från Wikipedia :
Speculating that small changes in history might have profound consequences on the present day world, scientist Sherman Weaver appropriates a prototype time machine to project himself back to the era of Philip II of Macedon. There he hopes to meet Aristotle. Believing that the influential ancient philosopher's lack of interest in experiment had retarded scientific progress through much of subsequent history, Weaver aims to nudge the savant in what he considers the proper direction - with the intention of creating a different Twentieth Century dominated by a super-science hundreds of years in advance of ours.
Weaver pretends to be a conventional traveler from India. Equipped with modern-day marvels, he attempts to demonstrate to his new acquaintance (Aristotle) the value of experimentation in the furtherance of knowledge. Weaver's task is complicated by the malicious mischief of Aristotle's students, the coterie of young Prince Alexander (subsequently Alexander the Great), and by being suspected as a spy for the King of Persia, against whom Philip is about to go to war. He is ultimately forced to defend himself with a handgun he has brought, and is on the point of being executed as a spy and murderer when he is snapped back into the present day when the effects of his time projection wear off.
Weaver finds himself in a world very different from the one he left – but not in the way he hoped. Aristotle, convinced that the tedious accumulation of experimental knowledge is beneath the dignity of civilized philosophy, and that it is a waste of time attempting to catch up to "India" in that regard, turns out to have come down strongly against the notion in his writings. The result is a backward present of petty states considerably behind Weaver's original timeline in technology. His own United States is not even a dream, its physical confines being controlled by various Amerindian nations influenced by but having long since thrown off any subjection to the civilizations of the Old World. Enslaved in one such state, Weaver is only delivered from endless drudgery after many years when his scholarly talents are finally recognized.
The narrative of the story is set forth by Weaver in a lengthy letter to an acquaintance curious as to his remarkable background, in which he concludes that he would have done better to leave well enough alone.
