Science fiction is a modern genre. Though writers in antiquity sometimes dealt with themes common to modern science fiction, their stories made no attempt at scientific and technological plausibility, the feature that distinguishes science fiction from earlier speculative writings and other contemporary speculative genres such as fantasy and horror. The genre formally emerged in the West, where the social transformations wrought by the Industrial Revolution first led writers and intellectuals to extrapolate the future impact of technology. By the beginning of the 20th century, an array of standard science fiction "sets" had developed around certain themes, among them space travel, robots, alien beings, and time travel (see below Major science fiction themes). The customary "theatrics" of science fiction include prophetic warnings, utopian aspirations, elaborate scenarios for entirely imaginary worlds, titanic disasters, strange voyages, and political agitation of many extremist flavours, presented in the form of sermons, meditations, satires, allegories, and parodies-exhibiting every conceivable attitude toward the process of techno-social change, from cynical despair to cosmic bliss.
