Famous quotes containing the word expression:
“Here and there a bird sang, a rose silenced her expression of him, and all the gaga flowers wondered. But they puzzled the wanderer with their vague wearinesses.”
—John Ashbery (b. 1927)
“While I shall not vote for the prohibition amendment, I would like to see a good, wholesome expression of temperance sentiment.... Personally I do not resort to force—not even the force of law—to advance moral reforms. I prefer education, argument, persuasion, and above all the influence of example—of fashion.”
—Rutherford Birchard Hayes (1822–1893)
“I do not know whether there be, as a rule, more vocal expression of the sentiment of love between a man and a woman, than there is between two thrushes. They whistle and call to each other, guided by instinct rather than by reason.”
—Anthony Trollope (1815–1882)
