Famous quotes containing the words units, time, ancient and/or history:
“Even in harmonious families there is this double life: the group life, which is the one we can observe in our neighbour’s household, and, underneath, another—secret and passionate and intense—which is the real life that stamps the faces and gives character to the voices of our friends. Always in his mind each member of these social units is escaping, running away, trying to break the net which circumstances and his own affections have woven about him.”
—Willa Cather (1873–1947)
“In the actual world—the painful kingdom of time and place—dwell care, and canker, and fear. With thought, with the ideal, is immortal hilarity, the rose of joy.”
—Ralph Waldo Emerson (1803–1882)
“Neither by night’s ancient fear,
The parting of hat from hair,
Pursed lips at the receiver,
Shall I fall to death’s feather.
By these I would not care to die,
Half convention and half lie.”
—Dylan Thomas (1914–1953)
“The one duty we owe to history is to rewrite it.”
—Oscar Wilde (1854–1900)
