Objects, people, abstract forms are often used in paintings to portray ideas. What types of objects, forms, or figurative representations change the psychology of the human ideals of truth? These are things that may shape thoughts and everyday decisions.
Marinetti founded the Futurist movement in the early 20th century Italy to revolutionize poetry, changing its orientation from the past to the future. He excoriated the museum and exalted the machine, rejected motionlessness and approved speed, disdained pacifism and praised violence. Eventually this kind of thinking led to Italian fascism, but prior to that unhappy occurrence, it did influence much timeless avant-garde art in many media (including painting) dissociated from politics.
That question is really a reflection of the multi-disciplinary work of René Magritte.
