Famous quotes containing the word planet:
“Thus will the fondest dream of Phallic science be realized: a pristine new planet populated entirely by little boy clones of great scientific entrepeneurs ... free to smash atoms, accelerate particles, or, if they are so moved, build pyramids—without any social relevance or human responsibility at all.”
—Barbara Ehrenreich (b. 1941)
