Book excerpt: John Rogers here addresses the literary and ideological consequences of the remarkable, if improbable, alliance between science and politics in seventeenth-century England. He looks at the cultural intersection between the English and Scientific Revolutions, concentrating on a body of work created in a brief but potent burst of intellectual activity during the period of the Civil Wars, the Interregnum, and the earliest years of the Stuart Restoration. Rogers traces the broad implications of a seemingly outlandish cultural phenomenon: the intellectual imperative to forge an ontological connection between physical motion and political action.
