Thomas Kuhn: a snapshot - The Philosophers' …

Kuhn took the incommensurability that prevented him from properly understanding Aristotle to be at least partly a linguistic, semantic matter. However, progress is not impossible, and one school may make a breakthrough whereby the shared problems of the competing schools are solved in a particularly impressive fashion.

In normal science the key theories, instruments, values and metaphysical assumptions that comprise the disciplinary matrix are kept fixed, permitting the cumulative generation of puzzle-solutions, whereas in a scientific revolution the disciplinary matrix undergoes revision, in order to permit the solution of the more serious anomalous puzzles that disturbed the preceding period of normal science.

This conservative resistance to the attempted refutation of key theories means that revolutions are not sought except under extreme circumstances. Musgrave, A. While this term suggests that normal science is not dramatic, its main purpose is to convey the idea that like someone doing a crossword puzzle or a chess problem or a jigsaw, the puzzle-solver expects to have a reasonable chance of solving the puzzle, that his doing so will depend mainly on his own ability, and that the puzzle itself and its methods of solution will have a high degree of familiarity.

Furthermore, this fact is hidden both by the continued use of the same term and by the same distortion of history that has affected our conception of Ptolemy and Copernicus. Turning to the philosophy of science, it was clear by the end of the s that the centreground was now occupied by a new realism, one that took on board lessons from general philosophy of language and epistemology, in particular referentialist semantics and a belief in the possibility of objective knowledge and justification.

His most obvious achievement was to have been a major force in bringing about the final demise of logical positivism. Thus, if paradigms are the measures of attempted puzzle-solutions, then puzzle-solutions developed in different eras of normal science will be judged by comparison to differing paradigms and so lack a common measure.

Indeed, before Kuhn, there was little by way of a carefully considered, theoretically explained account of scientific change. Kuhn's work has also been used in the Arts and Humanities, such as by Matthew Edward Harris to distinguish between scientific and historical communities such as political or religious groups : 'political-religious beliefs and opinions are not epistemologically the same as those pertaining to scientific theories'.

In one, solutions are compounds, in the other mixtures. Personality may play a role in the acceptance of a theory, because, for example, one scientist is more risk-averse than another c, —but that is still a relationship to the scientific evidence. Consensus on the puzzle-solution will thus bring consensus on these other aspects of a disciplinary matrix also.

Perspectives Antihumanism Empiricism Rationalism Scientism. Although Kuhn asserted a semantic incommensurability thesis in The Structure of Scientific Revolutions he did not there articulate or argue for the thesis in detail. Non-Euclidean geometry s Uncertainty principle Nyhart — Angela N. According to Kuhn, it is the incompleteness and imperfection of the existing data-theory fit that define the puzzles that characterise normal science.

On the one hand, positivists required of a science that it should be verifiable by reference to its predictive successes. In , Kuhn accepted a post at the University of California—Berkeley, where in he became a full professor of history of science.
