Famous quotes containing the words concrete and/or wall:
“A sociosphere of contact, control, persuasion and dissuasion, of exhibitions of inhibitions in massive or homeopathic doses...: this is obscenity. All structures turned inside out and exhibited, all operations rendered visible. In America this goes all the way from the bewildering network of aerial telephone and electric wires ... to the concrete multiplication of all the bodily functions in the home, the litany of ingredients on the tiniest can of food, the exhibition of income or IQ.”
—Jean Baudrillard (b. 1929)
“I think we will live through his term, Archie, and I’ll tell you something, old man, if they don’t stop hammering me, first Bryan for not enforcing the Anti-Trust Law and Wall Street for enforcing it, they may succeed in electing me to another term whether I want it or not.”
—William Howard Taft (1857–1930)
