I would disagree. I feel that it was the English Enlightenment, Locke, et.al, who most influenced the Founders. The extremisms of Voltaire, Rousseau, and more dangerously St. Juste, are not found in the balanced work that is the Constitution. Also there is genuine effort to protect the minority from the evils of the untrammeled majority. Something the French Revolution lacked and Europe lacks even today.
Most definitely. Many have noted the great contrasts between the successful American and failed French revolutions. The Americans, as de Toqueville noted, found it impossible to separate God and government whereas the French have never recovered from the tryst with secularism.
