Famous quotes containing the word science:
“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)
“The true knowledge or science which exists nowhere but in the mind itself, has no other entity at all besides intelligibility; and therefore whatsoever is clearly intelligible, is absolutely true.”
—Ralph J. Cudworth (1617–1688)
