Famous quotes containing the words black, hole and/or system:
“In families children tend to take on stock roles, as if there were hats hung up in some secret place, visible only to the children. Each succeeding child selects a hat and takes on that role: the good child, the black sheep, the clown, and so forth.”
—Ellen Galinsky (20th century)
“Wondrous hole! Magical hole! Dazzlingly influential hole! Noble and effulgent hole! From this hole everything follows logically: first the baby, then the placenta, then, for years and years and years until death, a way of life. It is all logic, and she who lives by the hole will live also by its logic. It is, appropriately, logic with a hole in it.”
—Cynthia Ozick (b. 1928)
“The system was breaking down. The one who had wandered alone past so many happenings and events began to feel, backing up along the primal vein that led to his center, the beginning of hiccup that would, if left to gather, explode the center to the extremities of life, the suburbs through which one makes one’s way to where the country is.”
—John Ashbery (b. 1927)
