Theories of Generative Art
In the most widely cited theory of generative art Philip Galanter describes generative art systems in the context of complexity theory. In particular the notion of Murray Gell-Mann and Seth Lloyd's effective complexity is cited. In this view both highly ordered and highly disordered generative art can be viewed as simple. Highly ordered generative art minimizes entropy and allows maximal data compression, and highly disordered generative art maximizes entropy and disallows significant data compression. Maximally complex generative art blends order and disorder in a manner similar to biological life, and indeed biologically inspired methods are most frequently used to create complex generative art. This view is at odds with the earlier information theory influenced views of Max Bense and Abraham Moles where complexity in art increases with disorder.
There are two additional points worth noting. Galanter notes that given the use of visual symmetry, pattern, and repetition by the most ancient known cultures generative art is as old as art itself. He also addresses the mistaken equivalence by some that rule-based art is synonymous with generative art. For example, some art is based on constraint rules that disallow the use of certain colors or shapes. Such art is not generative because constraint rules are not constructive, i.e. by themselves they don't assert what is to be done, only what cannot be done.
In a later article Margaret Boden and Ernest Edmonds present an overview of generative art and allied practices to develop a more precise language for critical discussion. They agree that generative art need not be restricted to that done using computers, and that some rule-based art is not generative. They go on to develop a technical vocabulary that includes Ele-art (electronic art), C-art (computer art), D-art (digital art), CA-art (computer assisted art), G-art (generative art), CG-art (computer based generative art), Evo-art (evolutionary based art), R-art (robotic art), I-art (interactive art), CI-art (computer based interactive art), and VR-art (virtual reality art).
In both accounts the term generative art does not describe an art movement, ideology, or theory of aesthetics. The term refers to how the art is made, and does not take into account why it was made or what the content of the artwork is.

Famous quotes containing the words theories of, theories, generative and/or art:
“Whatever practical people may say, this world is, after all, absolutely governed by ideas, and very often by the wildest and most hypothetical ideas. It is a matter of the very greatest importance that our theories of things that seem a long way apart from our daily lives, should be as far as possible true, and as far as possible removed from error.”
—Thomas Henry Huxley (1825–95)
“In the course of a life devoted less to living than to reading, I have verified many times that literary intentions and theories are nothing more than stimuli and that the final work usually ignores or even contradicts them.”
—Jorge Luis Borges (1899–1986)
“Hence, a generative grammar must be a system of rules that can iterate to generate an indefinitely large number of structures. This system of rules can be analyzed into the three major components of a generative grammar: the syntactic, phonological, and semantic components.”
—Noam Chomsky (b. 1928)
“American thinking, when it concerns itself with beautiful letters as when it concerns itself with religious dogma or political theory, is extraordinarily timid and superficial ... [I]t evades the genuinely serious problems of art and life as if they were stringently taboo ... [T]he outward virtues it undoubtedly shows are always the virtues, not of profundity, not of courage, not of originality, but merely those of an emasculated and often very trashy dilettantism.”
—H.L. (Henry Lewis)
