“Paris in the twentieth century” contains the characteristic features of the “classic” Jules Verne. This is called science fiction,. but that he rather had scientific foresight (in the novel there is already a subway , Vehicles with internal combustion engine , Powered by Hydrogen, and faxes , and computing machines, and electric cars and more). But the admiration for scientific and technical genius that we are familiar with from other works of the writer is combined with a warning to humanity: a civilization where two gods are worshiped - a machine and money, carries a threat of spiritual degradation. And finally, another shade of novelty: instead of traveling and adventures, the plot is based on a love story.
