The aim of this translation is the same as that of the original work. Each is the outcome of experience in university instruction in philosophy, and is intended to furnish a manual which shall be at once scientific and popular, one to stand midway between the exhaustive expositions of the larger histories and the meager sketches of the compendiums. A pupil of Kuno Fischer, Fortlage, J.E. Erdmann, Lotze, and Eucken among others, Professor Falckenberg began his career as Docent in the university of Jena. In the year following the first edition of this work he became Extraordinarius in the same university, and in 1888 Ordinarius at Erlangen, choosing the latter call in preference to an invitation to Dorpat as successor to Teichmuller."
