![]() ![]() The 'revolutionary paradigm shift' is, not a smooth adaptation of prior theories. As more anomalous observations become 'well corroborated' as ad hoc adjustments and auxiliary hypotheses begin to contradict one another as theories become self-contradictory in order to account for anomalies without transcending the paradigm, then the scientist, and the scientific community as a whole has to rethink the guiding principles of the paradigm. Only as anomolies begin to accrue, do they have an effect. Thus the cycle goes on indefinitely.Īn anomaly, for Kuhn, is an 'observational' result which the theory (or theories) within a paradigm is unable to account for but which has been produced within the paradigm. The work of normal science once again is to develop, articulate and specify the theory or theories embodied in the new paradigm and as before anomalies will appear leading to a further crisis and again, eventually, a paradigmatic shift. This is Kuhn's conception of 'progress' in science. The new paradigm is characterised, eventually, by its ability to explain all that the old paradigm could, plus some of the anomalies. there is a 'revolutionary paradigm shift'. A revolution takes place and a new paradigm replaces the old one, i.e. This work leads inevitably to anomalies, to adjustments to theories within a particular paradigmatic conception, then ultimately to irresolvable anomalies and ad hoc amendments leading to a 'crisis' in the paradigm. The sequence of events in science, according to the mechanism proposed by Kuhn, is from a pre-paradigmatic (or non-scientific stage) to the emergence of a paradigm that marks the beginning of the scientific stage of the subject as it allows for 'normal' scientific work to progress. A paradigm provides pragmatic guides to normal scientific activity in the shape of exemplary procedures and examples of work which exemplify the nature of the paradigmatic constraints on the scientist. A paradigm embodies a subliminal metaphysical core that is quite incontrovertible but which is rarely explicit. Kuhn tends to view these guiding principles in two ways.įirst, in a metaphysical sense. Kuhn regards a paradigm as a framework that constrains scientific activity through the embodiment of a set of guiding principles. Such revolutions embody a fundamental shift of ideas and are not evident in the usual practice of science.Ī paradigm is thus the prevailing conceptualisation of science (or of a scientific discipline) within which scientists operate in order to address problems. Paradigm shifts are relatively rare and constitute revolutions in theory. Anomolies are observed phenomena that cannot be explained by existing scientific theory. ![]() This shift comes about as a result of the inability of the prevailing conceptualisation to deal with anomolies. The model presupposes that science 'grows' through shifts in the basic conceptions operated by the scientific community. It thus emphasises the developmental nature of the progress of science. Kuhn's paradigm thesis is a model of the mechanism by which science 'progresses'. The paradigmatic model of the production of scientific knowledge derives from the work of Thomas Kuhn. See Kuhn's paradigmatic model for more detail. As a result of extensive discussion and usage in fields beyond the philosophy and history of science, the term paradigm has adopted diverse meanings to the extent that the original Kuhnian conception of the paradigm theory of science has been fundamentally corrupted in some cases. It has been developed widely in the social sciences. This work is most closely associated with the historian of science Thomas Kuhn. The paradigm serves to provide a taken-for-granted view of basic accepted scientific propositions. It provides the guiding principles that enable science. A paradigm, in this sense, is an overarching conceptualisation of science within which scientists operate. ![]() ![]() In the philosophy of science, paradigm refers to a model of the nature of the development of science. ![]()
