Marinetti expressed a passionate loathing of everything old, especially political and artistic tradition. "We want no part of it, the past", he wrote, "we the young and strong "Futurists!"" The Futurists admired speed, technology, youth and violence, the car, the airplane and the industrial city, all that represented the technological triumph of humanity over nature, and they were passionate nationalists. They repudiated the cult of the past and all imitation, praised originality, "however daring, however violent", bore proudly "the smear of madness", dismissed art critics as useless, rebelled against harmony and good taste, swept away all the themes and subjects of all previous art, and gloried in science.
