Famous quotes containing the word essential:
“Webster never goes behind government, and so cannot speak with authority about it. His words are wisdom to those legislators who contemplate no essential reform in the existing government; but for thinkers, and those who legislate for all time, he never once glances at the subject.... Comparatively, he is always strong, original, and, above all, practical. Still, his quality is not wisdom, but prudence.”
—Henry David Thoreau (1817–1862)
