By the end of the eighteenth century, the French dominated the world of science. And although science and politics had little to do with each other directly, there were increasingly frequent intersections.

Charles Gillispie explores how the links between science and polity in France were related to governmental reform, modernization of the economy, and professionalization of science and engineering.
