What seems to suggest various avant-garde and artistic experimentalism movements from futurism to cubism, from expressionism to surrealism, from Picasso to the great masters of informal art is a Beauty of challenge. The avant-garde art does not arise the issue of Beauty. It is understood without saying that the new images are "beautiful" in terms of art and that should produce the same pleasure that feel the contemporaries of Rafael and Giotto in front of their works” asserts Umberto Eco (Eco, 2005). The phenomenon is due to the fact that the challenge of avant-garde tear down all aesthetic canons, observed at the moment. Art no longer aims to offer images of natural beauty, no longer occasion for calm pleasure of contemplation the harmonious forms. Instead, it wants to lead to an interpretation of the world from a different optic, wants to return to archaic or exotic models: the universe of dreams or ill mentally fantasies, visions experienced under the drugs influence, rediscovering matter, chaotic household objects current location in contexts unlikely (new object, Dadaist movement etc.), unconscious impulses, of uncertainties, of confusion, of neutrality. The study aims to explore Beauty and ugly in terms of neutrosophic concept.
