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

This intriguing and ground-breaking book is the first in-depth study of the development of philosophy of science in the United States during the Cold War. It documents the political vitality of logical empiricism and Otto Neurath's Unity of Science Movement when these projects emigrated to the US in the 1930s and follows their de-politicization by a convergence of intellectual, cultural and political forces in the 1950s. Students of logical empiricism and the Vienna Circle treat these as strictly intellectual non-political projects. In fact, the refugee philosophers of science were highly active politically and debated questions about values inside and outside science, as a result of which their philosophy of science was scrutinized politically both from within and without the profession, by such institutions as J. Edgar Hoover's FBI. It will prove absorbing reading to philosophers and historians of science, intellectual historians, and scholars of Cold War studies.

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
