Famous quotes containing the word burs:
“Have we no culture, no refinement,—but skill only to live coarsely and serve the Devil?—to acquire a little worldly wealth, or fame, or liberty, and make a false show with it, as if we were all husk and shell, with no tender and living kernel to us? Shall our institutions be like those chestnut burs which contain abortive nuts, perfect only to prick the fingers?”
—Henry David Thoreau (1817–1862)
