cultivated (person) n.: bel esprit

Momigliano [showed] that the “antiquarians” of the sixteenth and seventeenth centuries were neither maniacal collectors nor narrow specialists, but strong and disciplined minds, philosophically well-equipped scholars [and] Gibbon, who detested the bel esprit side of the Enlightenment, was the heir of these scholars, and he knew it. (Marc Fumaroli, The Antiquarian as Hero, The New Republic, 05/28/2001.)

This word, when used in the above sense, can also be a synonym for intelligent, polished, refined or urbane.
