Thomas Kuhn quote image about scientific progress and new discoveries

Thomas Samuel Kuhn (1922–1996) was one of the influential philosophers of science of the 20th century. In his major work, “The Structure of Scientific Revolutions,” he described the development of science as a sequence of periods of normal science interrupted by scientific revolutions. He is particularly associated with the concept of the paradigm shift and with the idea that different paradigms may be incommensurable.

"The man who is striving to solve a problem defined by existing knowledge and technique is not, however, just looking around. He knows what he wants to achieve, and he designs his instruments and directs his thoughts accordingly. Unanticipated novelty, the new discovery, can emerge only to the extent that his anticipations about nature and his instruments prove wrong... There is no other effective way in which discoveries might be generated." Thomas Kuhn

"Individuals who break through by inventing a new paradigm are almost always either very young men or very new to the field whose paradigm they change. These are the men who, being little committed by prior practice to the traditional rules of normal science, are particularly likely to see that those rules no longer define a playable game and conceive another set that can replace them." Thomas Kuhn
