The collection consists chiefly of selected correspondence of Warner Fite. The bulk consists of letters addressed to Fite from Miguel de Unamuno, the Spanish essayist, poet, and philosopher, and Ramiro de Maeztu, also a Spanish political theorist, journalist, and literary critic. Their correspondence revolves around Fite's work, including his book Moral Philosophy, The Critical View of Life. There is a letter from Prof. J. Helder asking Fite to translate a letter (in Spanish) from Unamuno, accompanied by Fite's translation, which includes holograph corrections in Greek. In addition, there are four letters by Fite to "Mrs. Rogers" (Jeanette Blumenthal Rogers) and one letter to Helen Blumenthal Waterman. Other correspondents include the Italian philosopher Benedette Croce, American philosophers and authors William James and George Herbert Palmer, and the Spanish philosopher, essayist, and poet George Santayana.
