Famous quotes containing the word science:
“In the new science of the twenty-first century, not physical force but spiritual force will lead the way. Mental and spiritual gifts will be more in demand than gifts of a physical nature. Extrasensory perception will take precedence over sensory perception. And in this sphere woman will again predominate.”
—Elizabeth Gould Davis (b. 1910)
“Political liberty, the peace of a nation, and science itself are gifts for which Fate demands a heavy tax in blood!”
—Honoré De Balzac (1799–1850)
“The well-educated young woman of 1950 will blend art and sciences in a way we do not dream of; the science will steady the art and the art will give charm to the science. This young woman will marry—yes, indeed, but she will take her pick of men, who will by that time have begun to realize what sort of men it behooves them to be.”
—Ellen Henrietta Swallow Richards (1842–1911)
