On the philosophy of history in general, see the works of Herder (Ideen zur Philosophie der Gesch. der Menschheit), Fred. Schlegel, Hegel (1840, transl. by Sibree, 1870), Hermann (1870), Rocholl (1878), Flint (The Philosophy of History in Europe. Edinb., 1874, etc.), Lotze (Mikrokosmus, bk. viith; 4th ed.1884; Eng. transl. by Elizabeth Hamilton and E. E. C. Jones, 1885, 3d ed.1888). A philosophy of church history is a desideratum. Herder and Lotze come nearest to it
