1. Tierney, Brian, Foundations of the Conciliar Theory: The Contributions of the Medieval Canonists from Gratian to the Great Schism (Cambridge: University Press, 1955), pp. 246–247. The recent study by Black, A. J., Monarchy and Community: Political Ideas in the Later Conciliar Controversy 1430–1450 (Cambridge: University Press, 1970) shows how, ironic as it seems, political monarchism, both secular and ecclesiastical, was the immediate successor and ideological beneficiary of the mature conciliar doctrine.

The works of Nicholas will be cited from Nicholai de Cusa Opera Omnia iussu et auctoritate Academiae Litterarum Heidelbergensis ad codicum fidem edita (Hamburg: Felix Meiner, 1932) wherever possible. Volume and page number of this edition will be given in parentheses. See Sigmund, Paul E., Nicholas of Cusa and Medieval Political Thought (Cambridge, Massachusetts: Harvard University Press, 1963), pp. 36–37.

The actual vote was taken in December 1436, but the question remained open pending negotiations with the Greeks and with the citizens of Avignon, the place favored by Bagel's majority.
6. Krämer, p. 47. According to the accepted doctrine of the conciliarists the decision of the pars maior should have prevailed. But the minority took the style pars sanior and found additional juridical consolation in the claim that their placet was shouted before the other!

The most recent contribution to the discussion is Meuthen, Erich, “Nikolaus von Kues in der Entscheidung zwischen Konzil und Papst,”in Nikolaus von Kues als Promotor der Ökumene, MFCG 9 (1971): 19–33. In his opinion subsequent research will not substantially alter Koch's conclusion that Cusanus' decision pivoted on aedificatio vs. destructio ecclesiae with the Greek reunion issue as its concrete expression. See n. 10, below.

Other explanations of Cusanus' behavior have ranged from avarice, alleged by Stumpf, Theodor, Die politischen Ideen des Nicolaus von Cues (Cologne, 1865), p. 101 (cited in Sigmund, p. 226 n.) to zealousness for harmony, asserted By Haubst, Rudolf, “Die leitenden Gedanken und Motive der cusanischen Theologie,” MFCG 4 (1964): 257–277. Most scholars have abandoned the single-motive explanations and see Cusanus as influenced by a complex of political or ecclesiastical considerations. For some examples see Bett, Henry, Nicholas of Cusa (London: Methuen, 1932), pp. 22, 28–30; Jacob, E. F., Essays in the Conciliar Epoch (Manchester: Manchester University Press, 1953), pp. 250–251; idem, Essays in Later Medieval History (Manchester: Manchester University Press, 1968), pp. 121–122; Jaspers, Karl, Nikolaus Cusanus (Munich: Deutscher Taschenbuch Verlag, 1968; first published, Munich: R Piper, 1964), pp. 180–190; Vansteenberghe, pp. 56–65; Watanabe, pp. 16, 97–98, 113–114.
12. Ibid., p. 280. In the case of Cesarini such a marked shift of thinking is not evident and one cannot, therefore, speak in terms of a “conversion.” This conclusion is convincingly demonstrated by Christianson, Gerald, “Cardinal Cesarini at the Council of Basel, 1431–1438” (Ph.D. dissertation, University of Chicago 1972), pp. 471–475. Christianson (p. 474 n. ) also rejects the opinion of Watanabe, Morimichi, “The Episcopal Election of 1430 in Trier and Nicholas of Cusa,” Church History: Studies in Christianity and Culture 39 (1970): 315, that the loss of The Manderscheid case was at the root of Cusanus' alienation from Basel. Christianson's observation that it was “unlikely that a man of his [Cusanus'] theological and canonistic training would have abandoned Basel for such a shallow motive” supports the present search for deeper motivation. Watanabe's position reflects that outlined by Vansteenberghe, pp. 56–65. The inadequacy of Sigmund's explanation was pointed out in Cranz's, F. Edward review of Sigmund's book, Speculum 41 (1966): 189–191. Cranz correctly evaluates the change as radical, that is, as altering “almost completely the metaphysical basis of politics and ecclesiology” (p. 191).

In this official capacity he also shared in the papal censure of excommunication leveled against Ulrich. Meuthen, Erich, Das Trierer Schisma von 1430 auf dem Basler Konzil.

23. Although the name Padua immediately suggests Marsilius and the Defensor pacis, his influence on the development of the conciliar theory is not yet clear. Cusanus, for example, confessed that he had not seen Marsilius' work until some ten years after leaving Padua. De concordantia catholica, 2:34 (14:297).
24. Ullmann, Walter, The Origins of the Great Schism (London, 1948), p. 193. Although it is true that Zabarella's nephew, Bartholomew Zabarella, taught at Padua during Cusanus' stay there, some caution must be observed in reading such remarks as that of Meuthen, Erich: “Die Tradition des Zabarella in Padua wurde zur Zeit des Cusanus forgesetzt durch seinen Neffen Bartholomäus Zabarella,” Nikolans von Kues 1401–1464: Skizze einer Biographie (Münster: Aschendorff, 1964), p. 16; or that of Watanabe (following Meuthen): “Zabarella's theories were expounded by his nephew Bartholomew Zabarella …,” “The Episcopal Election,” p. 301. At Basel Bartholomew took the papal side against Cesarini. See Palacký, František et al. , eds., Monumenta conciliorum generalium seculi decimi quinti, 4 vols.

30. Sigmund, p. 280. The radical nature of the change becomes clearer when one realizes that Cusanus was actively pursuing conciliar projects at least until the end of 1436 and did not break with Basel until the summer of 1437. By October 1438 he was representing the pope at the Nürnberg Reichstag. In the interim he traveled to Constantinople as a member of the so-called minority party but in fact as a papal representative.
31. “Nun autem exitus causarum ostendit veritatem de concilio ycomenico cum Grecis habito; exitus edocuit electionem ociam eorum, qui in numero minores fuerunt, veram et sanctam fuisse, quoniam ibi reductio et unio facta est, hic scisma.” Cusanus-Texte: IV.

35. Gill, Joseph, The Council of Florence (Cambridge: University Press, 1959) manages to communicate something of that sense of impatience with theological hairsplitting felt by both sides. As Bessarion pointed out, the ancient theologians revered by either Greeks or Latins were actually saying the same thing even though their words were different [!]. Ibid., p. 240. For the complete text of Bessarion's remarks see Migne, , Patrologia Graeca, 161:543–612.
36. Without presuming to deny “the central importance of literary preoccupations in Renaissance humanism” spoken of by Kristeller, Paul Oskar, Renaissance Thought: The Classic, Scholastic and Humanist Strains (New York: Harper and Row, Harper Torchbook edition, 1961), p. 11, it is the broad cultural phenomenon which humanism had become by the early fifteenth century that interests us here. Studies construing the terms “humanist” and “humanism” more narrowly were understandably forced to regard Cusanus as only marginally a humanist, if at all. See, for example, Seidlmayer, Michael, “Nikolaus von Cues und der Humanismus,” in Humanismus, Mystik und Kunst in der Welt des Mittelalters, vol. 3 of Studien und Texte zur Geistesgeschichte des Mittelalters, ed. by Koch, Josef (Leiden and Cologne: E. J. Brill, 1953), p. 3; Sigmund, p. 30; Meuthen, , Skizze, p. 32 and Garin, Eugenio, “Cusano e i platonici italiani del quattrocento,” in Nicolo' da Cusa, Relazioni tenute al Convegno Interuniversitario di Bressanone nel 1960 (Florence: G. C. Sansoni, 1962), pp. 75–100. In what seems to be a significant modification of an earlier position, the recent article of Kristeller, Paul Oskar, “A Latin Translation of Gemistos Plethon's De fato by Johannes Sophianos Dedicated to Nicholas of Cusa,” in Nicolo' Cusano agli inizi del mondo moderno:Atti del Congresso internazionale in occasione del V centenario della morte de Nicolo' Cusano, Bressanone, 6–10 settembre 1964 (Florence: G. C. Sansoni, 1970), p. 177 allegedly “strengthens the case for Cusanus' close connection both with Renaissance humanism and with the philosophical traditions of Platonism, connections that have been doubted or minimized by some recent students of the subject.” This article cites nearly all of the standard works dealing with the early humanist connections of Cusanus as well as those describing the humanist MSS possessed by Cusanus. The reader might also be referred to the comments of Trinkaus, Charles, In Our Image and Likeness: Humanity and Divinity in Italian Humanist Thought (London: Constable, 1970), 1:14–15.

47. Ibid., pp. 117–127. About Poggio, for instance, Martines concludes (p. 127) that “owing to his lucrative affiliation with the papal curia, owing to his humanistic connections, his commercial acumen, and his Florentine friendships, Ser Poggio (later Messer) managed to raise his family to the economic level of the city's oligarchical households.”

Similar sentiments were expressed by many others, among them the archbishop of Mainz: “Se ammirari, quod cum haberet latam et amplam diocesim et provinciam, quod simplex in sacro concilio tantam vocem habere deberet sicut sui ambasiatores …” Quoted in Meuthen, “Entscheidung,” p. 32 n. On the composition of the Council of Basel see Ourliac, “La sociologie,” pp. 5–32.
56. Whitehead's remarks about the “enlargement of thought” produced by travel find confirmation in this experience of Cusanus. “An individual who travels meets strangers on terms of kindliness. He returns home, and in his person and by his example promotes the habit of thinking dispassionately beyond the tribe. The history of rational religion is full of tales of disengagement from the immediate social routine.” The result is the development of a “world-consciousness” as contrasted with a “social consciousness”.

67. Cusanus' letter of August 4, 1439 to Tommaso Parentucelli asks him to urge Traversari on in translating Proclus: “Dimisi apud generalem Cameldunensium Proclum de theologia Platonis ut transferret. Supplico instantissime, quoniam nune vacare liberius poterit. Solicita eum.” Koch, , Briefweschel, Ep. 3, p. 35.

68. The emotional breakdown described by Pius II corroborates the distinct impression, gained after a careful study of Cusanus' life and works, that Nicholas was not a happy person. See Gabel, and Gragg, , Memoirs, pp. 227–230.

70. This judgment is based on a study of Codd. Vat. Lat. 1244 and 1245 containing the collected sermones. The only extensive edition is that of Jacques Lefevre d'Etaples, Paris, 1514. These heavily edited selections—Excitationum libri X—were undoubtedly chosen because they dealt with themes beloved by the humanists, and taken by themselves they are therefore somewhat misleading.
