Douglas Hofstadter in the context of Gödel, Escher, Bach

Systems novel is a literary genre named by Tom LeClair in his 1987 book In the Loop: Don DeLillo and the Systems Novel, and explored further in LeClair's 1989 book, The Art of Excess: Mastery in Contemporary American Fiction. LeClair used systems theory to critique novels by authors including Thomas Pynchon, William Gaddis and Ursula K. Le Guin. Citing Fritjof Capra's description of systems theory as a "new vision of reality", LeClair invoked ideas from thinkers such as James Lovelock, Gregory Bateson and Douglas Hofstadter to analyse how the novels in question depicted processes and relationships within social, cultural, economic and political systems. LeClair's systems novels were all "long, large and dense" and all in some way striving for "mastery", showing similarity to Moby-Dick and Absalom, Absalom! in "range of reference, artistic sophistication, and desire for profound effect."

Subsequent critics widened the geographical range but mostly adhered to the notion that systems novels were typically large and dense, making the concept overlap with other critical terms such as encyclopedic novel and maximalism. This weakened its usefulness as a genre definition, but with the rise of the internet, the systems novel has come to be seen as reflecting the conditions of network culture. The term is now used in at least two different ways, stemming from LeClair's thesis though with different emphases. One highlights bulk, broadness of scope, range of content and greatness of ambition. The other highlights engagement with scientific and technological concepts such as information theory, complexity and emergence. Some systems novels fit both categories, though not all.

In economics and game theory, a participant is considered to have superrationality (or renormalized rationality) if they have perfect rationality (and thus maximize their utility) but assume that all other players are superrational too and that a superrational individual will always come up with the same strategy as any other superrational thinker when facing the same problem. Applying this definition, a superrational player who assumes they are playing against a superrational opponent in a prisoner's dilemma will cooperate while a rationally self-interested player would defect.

This decision rule is not a mainstream model in game theory and was suggested by Douglas Hofstadter in his article, series, and book Metamagical Themas as an alternative type of rational decision making different from the widely accepted game-theoretic one. Hofstadter provided this definition: "Superrational thinkers, by recursive definition, include in their calculations the fact that they are in a group of superrational thinkers."

Over a period of 24 years (January 1957 – December 1980), Martin Gardner wrote 288 consecutive monthly "Mathematical Games" columns for Scientific American magazine. During the next 5+1⁄2 years, until June 1986, Gardner wrote 9 more columns, bringing his total to 297. During this period other authors wrote most of the columns. In 1981, Gardner's column alternated with a new column by Douglas Hofstadter called "Metamagical Themas" (an anagram of "Mathematical Games"). The table below lists Gardner's columns.

Twelve of Gardner's columns provided the cover art for that month's magazine, indicated by "[cover]" in the table with a hyperlink to the cover.
