Famous quotes containing the words grey and/or world:
“Let the erring sisters depart in peace; the idea of getting up a civil war to compel the weaker States to remain in the Union appears to us horrible to the last degree.”

“It is clear that everybody interested in science must be interested in world 3 objects. A physical scientist, to start with, may be interested mainly in world 1 objects—say crystals and X-rays. But very soon he must realize how much depends on our interpretation of the facts, that is, on our theories, and so on world 3 objects. Similarly, a historian of science, or a philosopher interested in science must be largely a student of world 3 objects.”
—Karl Popper (1902–1994)
