Paradoxes and Contradictions is the sequel to Harry's Time Tours. It an an expansive and humorous overview of human development. Harry D. Black was born in 1982 in a different space-time. He studied Physics, programming, and time travel in college. After graduation, he was hired by Ouranos Corporation, the big time travel company, and he wrote software for them for several years, then he was transferred to training and troubleshooting. In 2014 for unknown reasons he was ejected from that space-time into this one. He arrived with a time machine and much of the documentation for it. This volume of Harry's activities is primarily about what happened subsequent to the Gods complaining about belligerent behavior of humans. Harry improved the matter, but physics required that what had happened couldn't be changed in this space-time.Paradoxes and Contradictions further details the life and activities of Harry and his partner, Mary. Highlights include bringing some people from the past into the Twenty-first century to cure them of what killed them, including Pope Joan, Edgar Allan Poe, and H. P. Lovecraft. The Gods asked how the universe could be improved. Harry's opinion was that it would be difficult or impossible to improve it, because of the deterministic nature of space-time. Harry's Interstellar subsidiary develops all of the Earth-like planets available, making Harry even wealthier. There is more potential in the Interstellar division, but it also produces problems, and as Earthers seek to escape Earth in greater numbers, there certainly will be more problems. In his centuries long career, remember the advantage of the pandemic virus, Harry changes history in the hope of improving the present, but he had already told the clients (the Gods) that it wouldn't work right; it only causes the space-time to bifurcate, so this space-time would be unchanged, but the newly created space-time would have the change. As you should remember, the Really Great Pandemic created the situation behind most of Harry's activities, when it eliminated more than ninety percent of the Earth's population, and the enhancements to Everett's Universal Wave Theory that Devlin made in many versions of apace-time provided the tools that Harry needed. For fun and profit, he plunders buried loot, and Lovecraft recovers the actual Ark of the Covenant. And he even added to evolution, by accident.But Harry is more interested in the how and why, rather than simply the actions. In the course of other events, readers will also learn more about the Gods and Goddesses, such as what is the story with Ekwamedha? And does Hebe actually make people younger?Also learn the truth about some events in antiquity: What really happened to Atlantis? And where was it? You may not care what will happen in the twenty-seventh century, but some of that history lies at your fingertips, and saving people who had died in the past can be interesting. Pope Joan was a woman of her time, the Dark Ages, but that didn't prevent her from becoming educated, taking holy orders in the ninth century and being elected Pope, but it also resulted in her going into labor during a procession a few years later, and she would have died from injuries inflicted by people who didn't want the Pope bearing children. But after the Really Great Pandemic, there will be demand for women as priests, but Christianity will be dying by then, and the old Faith has no trouble accommodating women, but imagine how Pope Joan will think about that. readers regret that Edgar Allan Poe died as he did; Harry and Mary did something about that. T hey saved him from that original death and brought him to the twenty-second century to cure him of the underlying problems, and he has lived happily since then. H.P. Lovecraft was treated similarly. Paradoxes and Contradictions will expand your understanding of the past, present, and future, and of the philosophical underpinnings of all.
