Famous quotes containing the words natural, selection and/or humans:
“It would seem that man was born a slave, and that slavery is his natural condition. At the same time nothing on earth can stop man from feeling himself born for liberty. Never, whatever may happen, can he accept servitude; for he is a thinking creature.”
—Simone Weil (1909–1943)
“Judge Ginsburg’s selection should be a model—chosen on merit and not ideology, despite some naysaying, with little advance publicity. Her treatment could begin to overturn a terrible precedent: that is, that the most terrifying sentence among the accomplished in America has become, “Honey—the White House is on the phone.””
—Anna Quindlen (b. 1952)
“The land is the host and humans merely guests.”
—Chinese proverb.
