Famous quotes containing the word heart:
“How frail the human heart must be—
a mirrored pool of thought.”
—Sylvia Plath (1932–1963)
“Royalty is a government in which the attention of the nation is concentrated on one person doing interesting actions. A Republic is a government in which that attention is divided between many, who are all doing uninteresting actions. Accordingly, so long as the human heart is strong and the human reason weak, Royalty will be strong because it appeals to diffused feeling, and Republics weak because they appeal to the understanding.”
—Walter Bagehot (1826–1877)
“My heart pumps yet the poison draught of you.”
—William Empson (1906–1984)
