Belles Lettres, (or Polite Literature, as it is properly denominated in English.) embraces grammar, logic, rhetoric, poetry, music, mathematics, and the learned languages ; these are usually called the seven Liberal arts. Belles Lettres and Criticism, says Dr. Blair, chiefly consider man as being endowed with those powers of taste and imagination which were intended to embellish his mind, and supply him with rational and useful entertainment. They open a field of investigation peculiar to themselves. All that relates to beauty, harmony, grandeur, and elegance, all that can soothe the mind, gratify the fancy, or move the affections, belong to their province.
