Possibly?

In its article on Leibniz, Wikipedia reports: “No philosopher has ever had as much experience with practical affairs of state as Leibniz, except possibly Marcus Aurelius.” Possibly? Privy Counselor of Justice to the House of Brunswick, trusted adviser to the Electress of Hanover and the Queen of Prussia, and Imperial Court Counselor to the Habsburgs are important positions, beyond the reach of most philosophers, but they hardly compare to being Emperor of Rome.
