Famous quotes containing the word defects:
“The defects and faults of the mind are like wounds in the body; after all imaginable care has been taken to heal them up, still there will be a scar left behind, and they are in continual danger of breaking the skin and bursting out again.”
—François, Duc De La Rochefoucauld (1613–1680)
“One of our defects as a nation is a tendency to use what have been called “weasel words.” When a weasel sucks eggs the meat is sucked out of the egg. If you use a “weasel word” after another there is nothing left of the other.”
—Theodore Roosevelt (1858–1919)
“We should endeavor practically in our lives to correct all the defects which our imagination detects.”
—Henry David Thoreau (1817–1862)
