 Reflecting the extraordinary range of his intellectual interests and concerns, the corpus of Humboldt’s writings consists of a wide spectrum of diverse types and genres of texts of which only a small portion was ever published during his lifetime. Until this day all editions of his works have remained incomplete. His texts consist of philosophical reflections, fragments, studies of varying types and length, notes, diaries, as well as entire treatises and monographs with themes ranging from political theory, anthropology, aesthetics, educational theory, literature and history to hermeneutics, ethnology, and last but not least, to philosophy of language and linguistics. Not to be omitted are the political memoranda produced at the time Humboldt held public office, many of which must be counted among his outstanding literary and intellectual achievements. There is in addition also a sizable corpus of translations from the works of Lucretius, Pindar, Aeschylus, Aristophanes and others (GS Vol 8) and of non-Western works such as the Bhagavad Gita as well as his own poetic productions (GS Vol 9). Last but not least, must be considered Humboldt’s extensive and extraordinarily rich correspondence that he maintained with a large number of the important personalities of the age throughout his entire life. Noteworthy among these are his correspondence with his wife Caroline (7 vols.), his brother Alexander, Franz Bopp, Karl-Gustav Brinkmann, Charlotte Diede (Briefe an eine Freundin), Friedrich Gentz, Johann Wolfgang von Goethe, Henriette Herz, Friedrich Jacobi, Christian Gottfried Körner, Friedrich Schiller, August Wilhelm Schlegel, Germaine de Staël, Friedrich Welcker and Friedrich Wolf. An entire group of his correspondence consists of exchanges with scholars in different parts of the world and is concerned with specific issues and problems. The bulk of these communications can be found among his extant linguistic papers where they have come down to us in the order in which Humboldt filed them. His political correspondence forms a separate category and has been published as part of the Academy edition in GS Vol 16, 17.
