Famous quotes containing the words major, concrete and/or structures:

    “You should hurry up ... and acquire the cigar habit. It’s one of the major happinesses. And so much more lasting than love, so much less costly in emotional wear and tear.”
    —Aldous Huxley (1894–1963)

    “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)

    “If there are people who feel that God wants them to change the structures of society, that is something between them and their God. We must serve him in whatever way we are called. I am called to help the individual; to love each poor person. Not to deal with institutions. I am in no position to judge.”
    —Mother Teresa (b. 1910)
