Famous quotes containing the word science:
“What would life be without art? Science prolongs life. To consist of what—eating, drinking, and sleeping? What is the good of living longer if it is only a matter of satisfying the requirements that sustain life? All this is nothing without the charm of art.”
—Sarah Bernhardt (1845–1923)
“The method of political science ... is the interpretation of life; its instrument is insight, a nice understanding of subtle, unformulated conditions.”
—Woodrow Wilson (1856–1924)
