KUHN AND PHILOSOPHY*

Extract

Initially trained as a physicist, Kuhn became a leading and extraordinarily influential figure in the history of science. He saw his work in the history of science as contributing to a novel philosophical conception of the nature of science. At the outset of Structure, for example, Kuhn announces his intention to replace the “development-by-accumulation” model he associates with the philosophical tradition before him—including, in particular, what he calls “early logical positivism”—with a new model of radical conceptual discontinuity or incommensurability. Structure was written during Kuhn's tenure teaching philosophy and history of science at Berkeley, and, shortly after its publication, he took up a new post as professor of philosophy and history of science at Princeton. From 1983 until his death in 1996 Kuhn was professor of philosophy at MIT, where he attempted further to articulate his conception of incommensurability, taking account of developments in linguistics and philosophy of language.

1 Kuhn, Thomas, The Structure of Scientific Revolutions (Chicago, 1970)Google Scholar begins by rejecting this model in chapter 1, although Kuhn does not there explicitly associate it with logical positivism. In chapter 9 of Structure, 98, however, he rejects the view, “closely associated with early logical positivism,” that “would restrict the range and meaning of an accepted theory so that it could not possibly conflict with any later theory that made predictions about some of the same natural phenomena.” Kuhn there opposes this view, and argues for incommensurability, using the example of Einsteinian relativity theory.

21 Carnap, Aufbau, §179. Carnap (ibid.) also explains the corresponding divergence with the Marburg school: “According to the conception of the Marburg School . . . the object is the eternal X, its determination is an incompletable task. In opposition to this it is to be noted that finitely many determinations suffice for the constitution of the object—and thus for its univocal description among the objects in general. Once such a description is set up the object is no longer an X, but rather something univocally determined—whose complete description then certainly still remains an incompletable task.”

22 As I indicated above, Carnap's mature standpoint adopts Wissenschaftslogik as the substitute for all forms of traditional epistemology, including the epistemology of the Aufbau.

30 Although he does acknowledge Cassirer's influence, Cohen, H. Floris, The Scientific Revolution (Chicago, 1994), 543Google Scholar, nonetheless contends that “only Burtt, Dijksterhuis, and Koyré were to elaborate such views [on the mathematization of nature] into detailed examinations of the birth of early modern science.” This contention is gainsaid by the text of Das Erkenntnisproblem itself, however, which treats Kepler, Galileo, Descartes, Bacon, and Newton (along with Copernicus, Bruno, Leonardo, Gilbert, Gassendi, Hobbes, Boyle, and Huygens) in quite considerable detail.

31 Meyerson, Identity and Reality, 388–9 (the quotation is from vol. 2 of Das Erkenntnisproblem).

32 Cassirer, Substance, 323–5. The passage continues, “But these [functional orders and coordinations (Ordnungen und Zuordungen)] do not exclude the moments of difference and change but only achieve determination in and with them. It is not manifoldness as such that is annulled [aufgehoben] but [we attain] only a manifold of another dimension: the mathematical manifold takes the place of the sensible manifold in scientific explanation. What thought requires is thus not the dissolution of diversity and change as such, but rather their mastery in virtue of the mathematical continuity of serial laws and serial forms” (ibid., original emphasis).

33 Koyré, Galileo, 223: “E. Cassirer, in his Erkenntnisproblem, vol. I, expresses the opinion that Galileo resurrected the Platonist ideal of scientific knowledge; from which follows, for Galileo (and Kepler), the necessity for mathematising nature . . . Unfortunately (at least in our opinion) Cassirer turns Plato into Kant. Thus, for him, Galileo's ‘Platonism’ is expressed by his giving priority to function and law over being and substance.”

35 Kuhn, Structure, 101–2.

36 See ibid., 206–7, which rejects all talk of convergence over time on the grounds that there is, “I think, no theory-independent way to reconstruct phrases like ‘really there’; the notion of a match between the ontology of a theory and its ‘real’ counterpart in nature now seems to me illusive in principle.” Kuhn continues (now speaking “as a historian”), “I do not doubt, for example, that Newton's mechanics improves on Aristotle's and that Einstein's improves on Newton's as instruments for puzzle-solving. But I can see in their succession no coherent direction of ontological development.”
