Of the numerous books and articles about Eucken which have appeared in Europe, it will be sufficient to mention: "Rudolf Eucken. Die Erneuerer des deutschen Idealismus", by Theodor Kappstein (Berlin-Schöneberg: Bucherlag der "Hilfe"); "Rudolf Eucken's Werk, Eine neue idealistische Lösung des Lebensproblems", by Kurt Kesseler (Bunzlau: Kreuschmer, 1911); "Eucken's dramatische Lebensphilosophie", by Otto Braun (Zeitschrift für Philosophie und Philosophische Kritik, 1909); "Rudolf Eucken's Christenthum", by Ludwig von Gerdtell (Verlag von Becker). On Eucken's seventieth birthday, January 5, 1916, the Zeitschrift für Philosophie published a Festschrift devoted to his work. "La philosophie de M. Rudolph Eucken", by Emile Boutroux (Académie des Sciences morales et politiques, 1910).
It is unnecessary to give a list of articles about Eucken in American magazines because any library that contains the files will have a periodical index, but a few references may be given: "Religious Philosophy of Eucken", Harvard Theological Review (vol. 2, p. 465, 1909); "Eucken and St. Paul", by Richard Roberts, Contemporary Review (vol. 97, p. 71); "Religious Philosophy of Eucken", by Baron F. von Hügel, Hibbert Journal (vol. 10, p. 660); "Eucken's Philosophy of Life", by W. Fite, The Nation (vol. 95, p. 29); "Eucken's New Gospel of Activism", Current Literature (vol. 53, p. 67); "Idealism of Rudolf Eucken", by S. H. Mellone, International Journal of Ethics (vol. 21, p. 15).
There are two excellent expositions of Eucken's philosophy in English, by his students and translators: "Rudolf Eucken's Philosophy of Life", by W. R. Boyce Gibson (Macmillan), and "An Interpretation of Rudolf Eucken's Philosophy", by W. Tudor Jones (Putnam). A briefer compendium, "Eucken: A Philosophy of Life", by A. J. Jones, has appeared in a series of handy volumes known as "The People's Books" (New York: Dodge Publishing Company). Meyrick Booth (Ph.D. of Jena) has published "Rudolf Eucken: His Philosophy and Influence," London (Unwin, 1913).
