A Theory About The Growth of Knowledge
"Evolutionary epistemology" can also refer to a theory that applies the concepts of biological evolution to the growth of human knowledge, and argues that units of knowledge themselves, particularly scientific theories, evolve according to selection. In this case, a theory—like the germ theory of disease—becomes more or less credible according to changes in the body of knowledge surrounding it.
One of the hallmarks of evolutionary epistemology is the notion that empirical testing does not justify the truth of scientific theories, but rather that social and methodological processes select those theories with the closest "fit" to a given problem. The mere fact that a theory has survived the most rigorous empirical tests available does not, in the calculus of probability, predict its ability to survive future testing. Karl Popper used Newtonian physics as an example of a body of theories so thoroughly confirmed by testing as to be considered unassailable, but which were nevertheless overturned by Einstein's bold insights into the nature of space-time. For the evolutionary epistemologist, all theories are true only provisionally, regardless of the degree of empirical testing they have survived.
Popper is considered by many to have given evolutionary epistemology its first comprehensive treatment, though Donald T. Campbell coined the phrase in 1974 (Schilpp, 1974).

Famous quotes containing the words theory, growth and/or knowledge:
“No one thinks anything silly is suitable when they are an adolescent. Such an enormous share of their own behavior is silly that they lose all proper perspective on silliness, like a baker who is nauseated by the sight of his own eclairs. This provides another good argument for the emerging theory that the best use of cryogenics is to freeze all human beings when they are between the ages of twelve and nineteen.”
—Anna Quindlen (20th century)
“Here commences what was called, twenty years ago, the best timber land in the State. This very spot was described as “covered with the greatest abundance of pine,” but now this appeared to me, comparatively, an uncommon tree there,—and yet you did not see where any more could have stood, amid the dense growth of cedar, fir, etc.”
—Henry David Thoreau (1817–1862)
“Test of the poet is knowledge of love,
For Eros is older than Saturn or Jove;
Never was poet, of late or of yore,
Who was not tremulous with love-lore.”
—Ralph Waldo Emerson (1803–1882)
