Famous quotes containing the word themes:
“In economics, we borrowed from the Bourbons; in foreign policy, we drew on themes fashioned by the nomad warriors of the Eurasian steppes. In spiritual matters, we emulated the braying intolerance of our archenemies, the Shi’ite fundamentalists.”
—Barbara Ehrenreich (b. 1941)
