Henry Flynt (born 1940 in Greensboro, North Carolina) is an American philosopher, musician, writer, activist, and artist connected to the 1960s New York avant-garde.

He became interested in logical positivism as a teenager, and later attended Harvard University on a scholarship, where he studied mathematics alongside companions Tony Conrad and John Alten.

In 1961, Flynt coined the term "concept art"[9] in the proto-Fluxus book An Anthology of Chance Operations[10] (co-published by Jackson Mac Low and La Monte Young), released in 1963,[11] alongside works by Fluxus artists such as George Brecht and Dick Higgins.

[15] Flynt read publicly from his text, From Culture to Veramusment, at Walter De Maria's loft on February 28, 1963—an act which can, in hindsight, be considered performance art.

[4] Flynt briefly performed violin with the Velvet Underground in 1966 as a fill-in for John Cale, and received guitar lessons from Lou Reed.

[6] In 1966, he recorded several rehearsal demo tapes with Walter De Maria, Art Murphy, and Paul Breslin in the garage rock band the Insurrections,[5] which were later compiled and released in 2004 on Locust Music as I Don't Wanna.

With Catherine Christer Hennix, Flynt formed the jazz-rock group Dharma Warriors in 1978, initially including Arthur Russell on keyboard.

[19] Flynt's early philosophical writings on logic and epistemology, including the 1961 draft of Philosophy Proper, was published in Milan in the book Blueprint for a Higher Civilization (1975).

Deriving broadly from his early arguments around "cognitive nihilism" and positivism, Flynt's work aims to overturn the dogmatic scientism and apparent coherence of contemporary scientific and mathematical discourse.

[20] In the late 1970s, he organized several meetings on the "crisis in physics" in an attempt to identify the areas where modern science represses incoherent or irrational logics in order to propagate its "objective" worldview.

[22] These concepts continue his work in sketching a worldview which would supersede scientific objectification and dissolve contemporary determinations of objective reality.
