About Thomas Kuhn
Thomas Samuel Kuhn (; July 18, 1922 – June 17, 1996) was an American historian and philosopher of science whose 1962 book The Structure of Scientific Revolutions was influential in both academic and popular circles. The book popularized the term paradigm shift, which has since become an English-language idiom. Kuhn made several claims concerning the progress of scientific knowledge: that scientific fields undergo periodic "paradigm shifts" rather than solely progressing in a linear and continuous way, and that these paradigm shifts open up new approaches to understanding what scientists would never have considered valid before; and that the notion of scientific truth, at any given moment, cannot be established solely by objective criteria but is defined by a consensus of a scientific community. Competing paradigms are frequently incommensurable; that is, there is no one-to-one correspondence of assumptions and terms. Thus, our comprehension of science can never rely wholly upon "objectivity" alone. Science must account for subjective perspectives as well, since all objective conclusions are ultimately founded upon the subjective conditioning/worldview of its researchers and participants. In honor of his legacy, the Thomas Kuhn Paradigm Shift Award is awarded by the American Chemical Society to speakers who present original views that are at odds with mainstream scientific understanding. Kuhn interviewed and tape recorded Danish physicist Niels Bohr the day before Bohr's death.
