I seemed to see a ghostly, indistinct figure sitting in a whirling mass of black and brass for a momenta figure so transparent that the bench behind with its sheets of drawings was absolutely distinct; but this phantasm vanished as I rubbed my eyes. The Time Machine had gone.Chap. XII, ¶19
The Time Machine: An Invention
H. G. Wells
A dreamer obsessed with traveling through time builds himself a time machine and, much to his surprise, travels over 800,000 years into the future. The world has been transformed with a society living in apparent harmony and bliss, but as the Traveler stays in this world of the future he discovers a hidden barbaric and depraved subterranean class. Wellss translucent commentary on the capitalist society was an instant bestseller and launched the time-travel genre.
