Is it significant, as the Conclusion suggests, that the Sorbonne is located between the Panthéon and the Préfecture de Police? French philosophy is associated with greatness and exercises considerable influence through the education system and grant funding, but in the wrong hands it could be an instrument of state control. The proximity of religious buildings to the Sorbonne also suggests that their influence has not been vanquished by the scepticism that characterized French philosophy from Descartes onward. The history of the French state has been driven by debates and fundamental questions about non-religious foundations of legitimacy. The history of French philosophy is marked by similar traits.
