Famous quotes containing the word power:
“I hate this shallow Americanism which hopes to get rich by credit, to get knowledge by raps on midnight tables, to learn the economy of the mind by phrenology, or skill without study, or mastery without apprenticeship, or the sale of goods through pretending that they sell, or power through making believe you are powerful, or through a packed jury or caucus, bribery and “repeating” votes, or wealth by fraud.”
—Ralph Waldo Emerson (1803–1882)
“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)
“His nature is too noble for the world;
He would not flatter Neptune for his trident,
Or Jove for’s power to thunder.”
—William Shakespeare (1564–1616)
