Famous quotes containing the word science:
“Nor has science sufficient humanity, so long as the naturalist overlooks the wonderful congruity which subsists between man and the world; of which he is lord, not because he is the most subtile inhabitant, but because he is its head and heart, and finds something of himself in every great and small thing, in every mountain stratum, in every new law of color, fact of astronomy, or atmospheric influence which observation or analysis lay open.”
—Ralph Waldo Emerson (1803–1882)
“No science is immune to the infection of politics and the corruption of power.”
—Jacob Bronowski (1908–1974)
“We have lost the art of living; and in the most important science of all, the science of daily life, the science of behaviour, we are complete ignoramuses. We have psychology instead.”
—D.H. (David Herbert)
