Famous quotes containing the word single:
“Philosophy is written in this grand book—I mean the universe—
which stands continually open to our gaze, but it cannot be understood unless one first learns to comprehend the language and interpret the characters in which it is written. It is written in the language of mathematics, and its characters are triangles, circles, and other geometrical figures, without which it is humanly impossible to understand a single word of it.”
—Galileo Galilei (1564–1642)
“...Negroes must concern themselves with every single means of struggle: legal, illegal, passive, active, violent and non- violent.... They must harass, debate, petition, boycott, sing hymns, pray on steps—and shoot from their windows when the racists come cruising through their communities.... The acceptance of our condition is the only form of extremism which discredits us before our children [ellipses in source].”
—Lorraine Hansberry (1930–1965)
“We know only a single science, the science of history. One can look at history from two sides and divide it into the history of nature and the history of men. However, the two sides are not to be divided off; as long as men exist the history of nature and the history of men are mutually conditioned.”
—Karl Marx (1818–1883)
