Yes and no. To some degree, Suprematism was an anti-rationalist movement. Not only was its founder, Kazimir Malevich, inspired by an anti-rationalist form of Russian Futurist poetry called Zaum, but he was also interested in mythical ideas, hoping his art would inspire the viewer to contemplate or commune with the divine. At the same time, other Suprematism artists such as Alexander Rodchenko rejected these mystical ideas, preferring to make connections with logic, science, and the laws of physics.
