In Dynamics of Reason, Michael Friedman uses the example of Galilean rectilinear inertia to support his defense of scientific rationality against postpositivist skepticism. However, Friedman's treatment of the case is flawed, such that his model of scientific change fails to fit the historical evidence. I present the case of Galileo, showing how it supports Friedman's view of scientific knowledge but undermines his view of scientific change. I then suggest reciprocal iteration as an amendment of Friedman's view that better accounts for scientific change.
