Famous quotes containing the word expression:
“The true poem is not that which the public read. There is always a poem not printed on paper,... in the poets life. It is what he has become through his work. Not how is the idea expressed in stone, or on canvas or paper, is the question, but how far it has obtained form and expression in the life of the artist. His true work will not stand in any princes gallery.”
—Henry David Thoreau (18171862)
“But the wise know that foolish legislation is a rope of sand, which perishes in the twisting; that the State must follow, and not lead the character and progress of the citizen; the strongest usurper is quickly got rid of; and they only who build on Ideas, build for eternity; and that the form of government which prevails, is the expression of what cultivation exists in the population which permits it.”
—Ralph Waldo Emerson (18031882)

—Rutherford Birchard Hayes (18221893)
