The Space Merchants

Science fiction is a genre of fiction dealing with imaginary but more or less plausible content such as future settings, futuristic science and... technology, space travel, aliens, and paranormal abilities. Exploring the consequences of scientific innovations is one purpose of science fiction, making it a "literature of ideas". Science fiction is largely based on writing rationally about alternative possible worlds or futures. It is similar to, but differs from fantasy in that, within the context of the story, its imaginary elements are largely possible within scientifically established or scientifically postulated laws of nature . The settings for science fiction are often contrary to known reality, but most science fiction relies on a considerable degree of suspension of disbelief, which is facilitated in the reader's mind by potential scientific explanations or solutions to various fictional elements. Science fiction elements include: Science fiction is difficult to define, as it includes a wide range of subgenres and themes.

Satire is primarily a literary genre or form, although in practice it can also be found in the graphic and performing arts. In satire, vices,... follies, abuses, and shortcomings are held up to ridicule, ideally with the intent of shaming individuals, and society itself, into improvement. Although satire is usually meant to be funny, its greater purpose is often constructive social criticism, using wit as a weapon. A common feature of satire is strong irony or sarcasm—"in satire, irony is militant"—but parody, burlesque, exaggeration, juxtaposition, comparison, analogy, and double entendre are all frequently used in satirical speech and writing. This "militant" irony or sarcasm often professes to approve of the very things the satirist wishes to attack. Satire is nowadays found in many artistic forms of expression, including literature, plays, commentary, and media such as lyrics. The word satire comes from the Latin word satur and the subsequent phrase lanx satura. Satur meant "full," but the juxtaposition with lanx shifted the meaning to "miscellany or medley": the expression lanx satura literally means "a full dish of various kinds of fruits.

Fiction is the form of any narrative or informative work that deals, in part or in whole, with information or events that are not factual, but... rather, imaginary—that is, invented by the author. Although fiction describes a major branch of literary work, it may also refer to theatrical, cinematic or musical work. Fiction contrasts with non-fiction, which deals exclusively with factual events, descriptions, observations, etc. . Realistic fiction, although untrue, could actually happen. Some events, people, and places may even be real. This is termed "faction". It can be possible that in the future imagined events could physically happen. For example, Jules Verne's novel From The Earth To The Moon, which at that time was just a product of his rich imagination, was proven possible in 1969, when Neil Armstrong and Buzz Aldrin set foot on the Moon, and the team returned safely to Earth. Realistic fiction strives to make the reader feel as if they're reading something that is actually happening—something that though not real, is described in a believable way that helps the reader make a picture as if it were an actual event.

Speculative fiction is an umbrella term encompassing the more fantastical fiction genres, specifically science fiction, fantasy, horror, supernatural... fiction, superhero fiction, utopian and dystopian fiction, apocalyptic and post-apocalyptic fiction, and alternate history in literature as well as related static, motion, and virtual arts. Speculative fiction as a category ranges from ancient works to both cutting edge, paradigm-changing and neotraditional works of the 21st century. Speculative fiction can be recognized in works whose authors' intentions or the social contexts of the versions of stories they portrayed is now known, since ancient Greek dramatists such as Euripides whose play Medea seems to have offended Athenian audiences when he fictionally speculated that shamaness Medea killed her own children instead of their being killed by other Corinthians after her departure, and whose Hippolytus, narratively introduced by Aphrodite, Goddess of Love in person, is suspected to have displeased his contemporary audiences because he portrayed Phaedra as too lusty.
