Famous quotes containing the word license:

—Henry David Thoreau (1817–1862)
“Purchasing power is a license to purchase power.”
—Raoul Vaneigem (b. 1934)
“Nature is mythical and mystical always, and works with the license and extravagance of genius. She has her luxurious and florid style as well as art.”
—Henry David Thoreau (1817–1862)
