Gregory Bateson in the context of Cybernetics

Meta-communication is a secondary communication (including indirect cues) about how a piece of information is meant to be interpreted. It is based on the idea that the same message accompanied by different meta-communication can mean something entirely different, including its opposite, as in irony. The term was brought to prominence by Gregory Bateson to refer to "communication about communication", which he expanded to: "all exchanged cues and propositions about (a) codification and (b) relationship between the communicators".

Ray L. Birdwhistell (September 29, 1918 – October 19, 1994) was an American anthropologist who founded kinesics as a field of inquiry and research. Birdwhistell coined the term kinesics, meaning "facial expression, gestures, posture and gait, and visible arm and body movements". He estimated that "no more than 30 to 35 percent of the social meaning of a conversation or an interaction is carried by the words." Stated more broadly, he argued that "words are not the only containers of social knowledge." He proposed other technical terms, including kineme, and many others less frequently used today.

Birdwhistell had at least as much impact on the study of language and social interaction generally as just nonverbal communication because he was interested in the study of communication more broadly than is often recognized. Birdwhistell understood body movements to be culturally patterned rather than universal. His students were required to read widely, sources not only in communication but also anthropology and linguistics. "Birdwhistell himself was deeply disappointed that his general communicative interests and goals were not appropriately understood." Collaborations with others, including initially Margaret Mead and Gregory Bateson, and later, Erving Goffman and Dell Hymes had huge influence on his work. For example, the book he is best known for, Kinesics and Context, "would not have appeared if it had not been envisaged by Erving Goffman" and he explicitly stated "the paramount and sustaining influence upon my work has been that of anthropological linguistics", a tradition most directly represented at the University of Pennsylvania by Hymes.

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.

Norbert Wiener (November 26, 1894 – March 18, 1964) was an American computer scientist, mathematician, and philosopher. He became a professor of mathematics at the Massachusetts Institute of Technology (MIT). A child prodigy, Wiener later became an early researcher in stochastic and mathematical noise processes, contributing work relevant to electronic engineering, electronic communication, and control systems.

Wiener is considered the originator of cybernetics, the science of communication as it relates to living things and machines, with implications for engineering, systems control, computer science, biology, neuroscience, philosophy, and the organization of society. His work heavily influenced computer pioneer John von Neumann, information theorist Claude Shannon, anthropologists Margaret Mead and Gregory Bateson, and others.
