¹ Dr. Karl A. Menninger discussing causes of high blood pressure before a conference of physicians. On this occasion “primal fear” was indicated as a clue (New York Times, April 20, 1948). Should not the historian of diplomacy in a deeper, more searching analysis of the fear of “encirclement” make use of this clue?

⁸ Did the United States and the New World go to war to redress the balance of the Old? It ought not to be considered election year maliciousness to refer for one of the first steps in this direction to statements by Henry Wallace, Democratic candidate for the Vice- Presidency in 1940, during that campaign. He told California audiences at that time that Japan's accession to the Axis meant “that the old balance of power upon which the U. S. relied for safety is now gone.Only if we are speedy and efficient in our defense can we keep aggressor nations, or any combination of them, from coming to this country … The old balance of power under which the Monroe Doctrine was easily defended is gone. We must look to our own defenses, relying on ourselves to repel any aggression.” UP dispatch from Los Angeles, September, 1940.

¹⁰ As an illustration: Long before publicists wrote of the state system in Europe as the necessary, unavoidable, quasi-lawlike connection and interdependence of the states there was Galileo's Didlogo dei due massimi sistemi del mondo (1632). Only around 1700 was the concept ‘system’ applied to the relationships between states.An anti-French author of the Spanish War of Succession wrote in 1701 Le portage du lion de la fable.II. partie, English translation The Fable of the Lion's Share verified in the pretended partition of the Spanish Monarchy, 1701, Repr. StateTracts III, 129 ff., addressing himself to the pope by saying that the Holy Father “certainly knew‘the system of Europe’ too well not to know that religion played no role in it.” A German encyclopedia of about the same time—Hübner's, JohannReales Staats, Zeitungsund Conversationslexicon, 1st ed.Leipzig, 1704Google Scholar (I amusing the 4th edition of 1709)—does not yet register this new concept which is certainly marking a further step in the secularization of politics, asGalileo had done in another time and place. According to this encyclopedia “Systema is such a bookin which a whole doctrine is extensively proposed. In astronomy it means the miraculous composition of the sky and earth.” For the further developmentof the concept of the European state system during the 18th century see Doerries, Heinrich, “Russlands Eindringen in Europa in der Epoche Peters des Grossen,” Osteuropmsche Forschungen N.

¹⁴ A large part of the above interpretation follows Hind, Arthur Mayger, A Catalogue of Early Italian Engravings preserved in the Departmentof Prints and Drawings in the British Museum, London, 1910, text vol., pp. 276 ff.Google Scholar, substantially reprinted in his Early Italian Engraving, New York London, 1938, text vol., pp. 251 ff. The woodcut is at length described by Schreiber, W. L., Handbuch der Holzund Metallschnitte des XV. Jahrhunderts, Leipzig, 1927, IV, 103.Google Scholar Schreiber is inclined todate the woodcut, which is of South German origin, perhaps from near the Bodensee, earlier than the engraving, while Hind insists on the priority of the latter. The woodcut is from the National Gallery of Artand is printed with their kind permission; knowledgeof it I owe to Professor E. Panofsky of Princeton. The 16th century German woodcut is in the Munich State Library and is reproduced in the Ullstein-Weltgeschichte, ed. Walter Goetz, Berlin, 1908–1925, vol. IV.

³⁴ A history in nuce of Edward Grey's diplomacy could be written in terms of the balance of power. His diplomacy was guided by that very idea, but the radicals within his own party, the heirs of Cobden and Bright, with their dislike of what went with the phrase balance of power, kept it from appearing in his parliamentary speeches and memoirs, both of which were designed to defend his diplomacy and the after all disastrous entry of England into the war in 1914.
