He studied history and humanities at the university of Moscow, and, after having gone through his military training in a grenadier regiment, left for Germany where he read political economy in Berlin under Prof. Schmoller.

But, if his truculent character was thus early displayed, his abilities were no less conspicuous; and, though still in his teens, he became lecturer on the Humanities at Tournai, whence, after but a short stay, he returned to Paris, to take his degree of doctor of canon law, and become regent of the college of Navarre.
