Hempel's proposal of covering laws which explain historical events has a certain plausibility, but can never be actually realized due to the chaotic nature of history. The natural laws that would govern both individual lives and greater history would be nonlinear; consequently, in the terminology of chaos theory, the final states of both are extremely sensitive to initial conditions. Initial conditions would need to be exactly known in order to account correctly for historic phenomena, especially for causes and effects which span long, historically interesting, lengths of time. Covering-law history therefore fails because the details of initial conditions are generally unknowable. Since this constraint diminishes as the time over which covering laws operate is divided into smaller consecutive intervals of scenes, covering-law explanations resolve into those having a narrative temporal structure

In the light of two unpublished letters from Carnap to Kuhn, this essay examines the relationship between Kuhn's The Structure of Scientific Revolutions and Carnap's philosophical views.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

I criticize conceptual pluralism, as endorsed recently by John Dupre and Philip Kitcher, for failing to supply strategies for demarcating science from non-science. Using creation-science as a test case, I argue that pluralism blocks arguments that keep creation-science in check and that metaphysical pluralism offers it positive, metaphysical support. Logical empiricism, however, still provides useful resources to reconfigure and manage the problem of creation-science in those practical and political contexts where pluralism will fail
