experiment with objects. Impact and influences While Surrealism is typically associated with the arts, it has impacted many other fields. In this sense, Surrealism does not specifically refer only to self-identified "Surrealists", or those sanctioned by Breton, rather, it refers to a range of creative acts of revolt and efforts to liberate imagination. In addition to Surrealist theory being grounded in the ideas of Hegel, Marx and Freud, to its advocates its inherent dynamic is dialectical thought. Surrealist artists have also cited the alchemists, Dante, Hieronymus Bosch, the Marquis de Sade, Charles Fourier, Comte de Lautréamont and Arthur Rimbaud as influences. May 68 Surrealists believe that non-Western cultures also provide a continued source of inspiration for Surrealist activity because some may induce a better balance between instrumental reason and imagination in flight than Western culture. Surrealism has had an identifiable impact on radical and revolutionary politics, both directly — as in some Surrealists joining or allying themselves with radical political groups, movements and parties — and indirectly — through the way in which Surrealists emphasize the intimate link between freeing imagination and the mind, and liberation from repressive and archaic social structures. This was especially visible in the New Left of the 1960s and 1970s and the French revolt of May 1968, whose slogan "All power to the imagination" quoted by The Situationists and Enragés from the originally Marxist “Rêvé-lutionary“ theory and praxis of Breton's French Surrealist group. Postmodernism and popular culture Many significant literary movements in the later half of the 20th century were directly or indirectly influenced by Surrealism. This period is known as the Postmodern era; though there is no widely agreed upon central definition of Postmodernism, many themes and techniques commonly identified as Postmodern are nearly identical to Surrealism. First Papers of Surrealism presented the fathers of surrealism in an exhibition that represented the leading monumental step of the avant-gardes towards installation art. Many writers from and associated with the Beat Generation were influenced greatly by Surrealists. Philip Lamantia and Ted Joans are often categorized as both Beat and Surrealist writers. Many other Beat writers show significant evidence of Surrealist influence. A few examples include Bob Kaufman, Gregory Corso, Allen Ginsberg, and Lawrence Ferlinghetti. Artaud in particular was very influential to many of the Beats, but especially Ginsberg and Carl Solomon. Ginsberg cites Artaud's "Van Gogh – The Man Suicided by Society" as a direct influence
