An artist is above all a human being, profoundly human to the core. If the artist can't feel everything that humanity feels, if the artist isn't capable of loving until he forgets himself and sacrifices himself if necessary, if he won't put down his magic brush and head the fight against the oppressor, then he isn't a great artist.
Diego RiveraAll art is propaganda. ... The only difference is the kind of propaganda. Since art is essential for human life, it can't just belong to the few. Art is the universal language, and it belongs to all mankind. All painters have been propagandists or else they have not been painters. ... Every artist who has been worth anything in art has been such a propagandist. ... Every strong artist has been a propagandist. I want to be a propagandist and I want to be nothing else. ... I want to use my art as a weapon.
