Famous quotes containing the word quotations:
“Reading any collection of a man’s quotations is like eating the ingredients that go into a stew instead of cooking them together in the pot. You eat all the carrots, then all the potatoes, then the meat. You won’t go away hungry, but it’s not quite satisfying. Only a biography, or autobiography, gives you the hot meal.”
—Christopher Buckley, U.S. author. A review of three books of quotations from Newt Gingrich. “Newtie’s Greatest Hits,” The New York Times Book Review (March 12, 1995)
“A book that furnishes no quotations is, me judice, no book—it is a plaything.”
—Thomas Love Peacock (1785–1866)
