As a rule, an author's correspondence possesses only a secondary interest, but Jacob Burckhardt's letters are of primary interest to students of history because of the nature of the man and of his major writings. It was in his letters, rather than in his lectures or longer works, that Burckhardt most directly addressed the currents of intellectual thought and social and political order-or disorder-of Europe in the nineteenth century. Not only are the letters addressed. to some of the most important thinkers of the time (Nietzsche, Burckhardt's younger colleague at the University of Basel, among them), but also they address some of the most pressing issues and the most important personages of the era. As the translator notes, the "letters, written from 1838 to 1897, have a lightness of touch, an informality and humor, and a breadth of vision that make one realize why he was the most civilized historian of his century. Their contents range across a vast field of interests. Art architecture, history, poetry, music, religion--all stirred him to contagious enthusiasm. His travels led him to Italy, Germany, France, and England, and to his letters we owe delightful and penetrating insights into the character of each country."
