We compare Carnap's and Kuhn's views on science. Although there are important differences between them, the similarities are striking. The basis for the latter is a pragmatically oriented semantic conventionalist picture of science, which suggests that the view that post-positivist philosophy of science constitutes a radical revolution which has no interesting affinities with logical positivism must be seriously mistaken.

In the light of two unpublished letters from Carnap to Kuhn, this essay examines the relationship between Kuhn's The Structure of Scientific Revolutions and Carnap's philosophical views. Contrary to the common wisdom that Kuhn's book refuted logical empiricism, it argues that Carnap's views of revolutionary scientific change are rather similar to those detailed by Kuhn. This serves both to explain Carnap's appreciation of The Structure of Scientific Revolutions and to suggest that logical empiricism, insofar as that program rested on Carnap's (...) shoulders, was not substantially upstaged by Kuhn's book.

The central ideas of logical, or scientific, empiricism as it developed during the twenties and early thirties in Vienna and in Berlin, grew out of collaborative efforts of scientifically interested philosophers and philosophically interested scientists. Those thinkers noted that while the claims made by the physical sciences were amenable to objective test by experiment and observation, the pronouncements put forward by metaphysics were incapable of any such objective critical appraisal. And while hypotheses advanced in the physical sciences would eventually be (...) accepted or rejected and thus lead to the growth of a body of objective scientific knowledge, the problems and pronouncements of metaphysics, inaccessible to objective appraisal, kept reappearing over and over again.
