Although the title of Kuhn’s essay specifies revolutions, his presentation has a broader scope, namely, the nature of scientific enterprise. His perspectives developed from consideration of the sequence of steps, from ancient Greece to the present, that resulted in twentieth century physical science. His philosophy of science stems, primarily, from historical study. He has, however, also considered psychology and sociology and applied them to the scientific endeavor as a whole. His approach is an interdisciplinary one.
In each of the thirteen short chapters, a single idea is set forth, usually drawing heavily on examples from the history of physics, chemistry, or astronomy, as would be expected given the author’s background. Yet the examples are secondary in importance to the notions that they are being invoked to explicate. Although familiarity with the physical science being cited is very helpful to the reader, lack of such knowledge is by no means a complete barrier to comprehension of Kuhn’s points.
Two features which distinguish Kuhn’s writing on the philosophy of science are his belief that revolution (not evolution) marks the development of science and his introduction of a set of terms to characterize scientific activity. Some of these terms were given new or expanded meanings by Kuhn and became identified with a “Kuhnian” approach. They have been seized upon by some readers and applied in fields widely divergent from the physical sciences.
Kuhn’s thinking about the development of science may be briefly summarized. At most given times, scientists pursuing a “mature” science practice “normal science” and teach it to their students, initiating them and training them to carry on in the then-established tradition for their particular discipline. For sciences which have reached a state of “maturity,” a “paradigm” has been established by consensus among the practitioners. For Kuhn, the term...
