What are revolutions?

Famous quotes containing the word revolutions:

“Generally speaking, the political news, whether domestic or foreign, might be written today for the next ten years with sufficient accuracy. Most revolutions in society have not power to interest, still less alarm us; but tell me that our rivers are drying up, or the genus pine dying out in the country, and I might attend.”
—Henry David Thoreau (1817–1862)

“We had no revolutions to fear, nor fatigues to undergo; all our adventures were by the fireside, and all our migrations from the blue bed to the brown.”
—Oliver Goldsmith (1728–1774)

“If we glance at the most important revolutions in history, we see at once that the greatest number of these originated in the periodical revolutions of the human mind.”
—Karl Wilhelm Von Humboldt (1767–1835)
