Famous quotes containing the words modern, warning, sign, shapes and/or colors:
“The ancients of the ideal description, instead of trying to turn their impracticable chimeras, as does the modern dreamer, into social and political prodigies, deposited them in great works of art, which still live while states and constitutions have perished, bequeathing to posterity not shameful defects but triumphant successes.”
—Herman Melville (1819–1891)
“We have not the motive to prepare ourselves for a “life-work” of teaching, of social work—we know that we would lay it down with hallelujah in the height of our success, to make a home for the right man. And all the time in the background of our consciousness rings the warning that perhaps the right man will never come. A great love is given to very few. Perhaps this make-shift time filler of a job is our life work after all.”
—Ruth Benedict (1887–1948)
“The desire to annoy no one, to harm no one, can equally well be the sign of a just as of an anxious disposition.”
—Friedrich Nietzsche (1844–1900)
“Runs falls rises stumbles on from darkness into darkness
and the darkness thicketed with shapes of terror
and the hunters pursuing and the hounds pursuing
and the night cold and the night long and the river
to cross and the jack-muh-lanterns beckoning beckoning
and blackness ahead”
—Robert Earl Hayden (1913–1980)
“In Haydn’s oratorios, the notes present to the imagination not only motions, as, of the snake, the stag, and the elephant, but colors also; as the green grass.”
—Ralph Waldo Emerson (1803–1882)
