World English Dictionary

Popper (ˈpɒpə)

—n
	Sir Karl. 1902--94, British philosopher, born in Vienna. In The Logic of Scientific Discovery (1934), he proposes that knowledge cannot be absolutely confirmed, but rather that science progresses by the experimental refutation of the current theory and its consequent replacement by a new theory, equally provisional but covering more of the known data. The Open Society and its Enemies (1945) is a critique of dogmatic political philosophies, such as Marxism. Other works are The Poverty of Historicism (1957), Conjectures and Refutations (1963), and Objective Knowledge (1972)

Popperian

—n, —*adj*

Matching Quote

"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
