Famous quotes containing the word vigilant:
“You are the current of the frozen stream,
Shadow invisible, ambushed and vigilant flame.”
—Allen Tate (1899–1979)
“I count him a great man who inhabits a higher sphere of thought, into which other men rise with labor and difficulty; he has but to open his eyes to see things in a true light, and in large relations; whilst they must make painful corrections, and keep a vigilant eye on many sources of error.”
—Ralph Waldo Emerson (1803–1882)
“The only free road, the Underground Railroad, is owned and managed by the Vigilant Committee. They have tunneled under the whole breadth of the land.”
—Henry David Thoreau (1817–1862)
