The Open Society and Its Enemies (Princeton Classics)

by Karl Popper

But it does so not by eradicating our prejudices all at once; it can eliminate them only one by one. The classical case in point is again Einstein’s discovery of our prejudices regarding time. Einstein did not set out to discover prejudices; he did not even set out to criticize our conceptions of space and time. His problem was a concrete problem of physics, the re-drafting of a theory that had broken down because of various experiments which in the light of the theory seemed to contradict one another. Einstein together with most physicists realized that this meant that the theory was false. And he found that if we alter it in a point which had so far been held by everybody to be self-evident and which had therefore escaped notice, then the difficulty could be removed. In other words, he just applied the methods of scientific criticism and of the invention and elimination of theories, of trial and error. But this method does not lead to the abandonment of all our prejudices; rather, we can discover the fact that we had a prejudice only after having got rid of it.
