Nicholas of Cusa (1401 – 11 August 1464), also referred to as Nicholas of Kues and Nicolaus Cusanus ( /kjˈsnəs/ ), was a German philosopher, theologian, jurist, and astronomer. One of the first German proponents of Renaissance humanism, he made spiritual and political contributions in European history. A notable example of this is his mystical or spiritual writings on "learned ignorance," as well as his participation in power struggles between Rome and the German states of the Holy Roman Empire.

Germans are a Germanic ethnic group native to Central Europe, who share a common German ancestry, culture and history. German is the shared mother tongue of a substantial majority of ethnic Germans.

Philosophy intellectual and/or logical study of general and fundamental problems

Philosophy is the study of general and fundamental questions about existence, knowledge, values, reason, mind, and language. Such questions are often posed as problems to be studied or resolved. The term was probably coined by Pythagoras. Philosophical methods include questioning, critical discussion, rational argument, and systematic presentation. Classic philosophical questions include: Is it possible to know anything and to prove it? What is most real? Philosophers also pose more practical and concrete questions such as: Is there a best way to live? Is it better to be just or unjust? Do humans have free will?

Theology Study of the nature of deities and religious belief

Theology is the critical study of the nature of the divine. It is taught as an academic discipline, typically in universities and seminaries. It occupies itself with the unique content of analyzing the supernatural, but also especially with epistemology, and asks and seeks to answer the question of revelation. Revelation pertains to the acceptance of God, gods, or deities, as not only transcendent or above the natural world, but also willing and able to interact with the natural world and, in particular, to reveal themselves to humankind. While theology has turned into a secular field, religious adherents still consider theology to be a discipline that helps them live and understand concepts such as life and love and that helps them lead lives of obedience to the deities they follow or worship.


As papal legate to Germany from 1446, he was appointed cardinal for his merits by Pope Nicholas V in 1448 and Prince–Bishop of Brixen two years later. In 1459 he became vicar general in the Papal States.

Papal legate a personal representative of the pope

A papal legate or apostolic legate is a personal representative of the pope to foreign nations, or to some part of the Catholic Church. He is empowered on matters of Catholic faith and for the settlement of ecclesiastical matters.

Pope Nicholas V Pope of Catholic Church from 1447 until 1455

Pope Nicholas V, born Tommaso Parentucelli, was Pope from 6 March 1447 until his death. Pope Eugene made him a cardinal in 1446 after successful trips to Italy and Germany, and when Eugene died the next year Parentucelli was elected in his place. He took his name Nicholas in memory of his obligations to Niccolò Albergati.

A vicar general is the principal deputy of the bishop of a diocese for the exercise of administrative authority and possesses the title of local ordinary. As vicar of the bishop, the vicar general exercises the bishop's ordinary executive power over the entire diocese and, thus, is the highest official in a diocese or other particular church after the diocesan bishop or his equivalent in canon law. The title normally occurs only in Western Christian churches, such as the Latin Church of the Catholic Church and the Anglican Communion. Among the Eastern churches, the Mar Thoma Syrian Church of Kerala uses this title and remains an exception. The title for the equivalent officer in the Eastern churches is syncellus and protosyncellus.

Nicholas of Cusa has remained an influential figure. In 2001, the sixth centennial of his birth was celebrated on four continents and commemorated by publications on his life and work. [2]

Birthplace in Kues

Nicholas was born in Kues (Latinized as "Cusa") in southwestern Germany. He was the second of four children of Johan Krebs (or Cryfftz) and Katherina Roemer. His father was "a prosperous boat owner and ferryman." [3] He entered the Faculty of Arts of the Heidelberg University in 1416 as "a cleric of the Diocese of Trier," studying the liberal arts. He seemed to have left Heidelberg soon afterwards, as he received his doctorate in canon law from the University of Padua in 1423. In Padua, he met with the later cardinals Julian Cesarini and Domenico Capranica and became friends with the mathematician Paolo dal Pozzo Toscanelli. Afterwards, he entered the University of Cologne in 1425 as "a doctor of canon law," which he appears to have both taught and practiced there. In Cologne, he made friends with the scholastic theologian Heymeric de Campo.

Bernkastel-Kues Place in Rhineland-Palatinate, Germany

Bernkastel-Kues is a well-known winegrowing centre on the Middle Moselle in the Bernkastel-Wittlich district in Rhineland-Palatinate, Germany. The town is a state-recognized health resort (Erholungsort), seat of the Verbandsgemeinde of Bernkastel-Kues and birthplace of one of the most famous German polymaths, the mediaeval churchman and philosopher Nikolaus von Kues (Cusanus).

Latinisation of names, also known as onomastic Latinisation, is the practice of rendering a non-Latin name in a Latin style. It is commonly found with historical proper names, including personal names, and toponyms, and in the standard binomial nomenclature of the life sciences. It goes further than romanisation, which is the transliteration of a word to the Latin alphabet from another script.

Heidelberg University public research university in Heidelberg, Baden-Württemberg, Germany

Heidelberg University is a public research university in Heidelberg, Baden-Württemberg, Germany. Founded in 1386 on instruction of Pope Urban VI, Heidelberg is Germany's oldest university and one of the world's oldest surviving universities. It was the third university established in the Holy Roman Empire.

Following a brief period in Cologne, Nicholas returned to his hometown and became secretary to Otto of Ziegenhain, the Prince–Archbishop of Trier. Otto appointed him canon and dean at the stift of Saint Florinus in Koblenz affiliated with numerous prebends. In 1427 he was sent to Rome as an episcopal delegate. The next year he travelled to Paris to study the writings of Ramon Llull. At the same time he rejected a calling by the newly established University of Leuven. He acquired great knowledge in the research of ancient and medieval manuscripts as well as in textual criticism and the examination of primary sources. In 1433 he identified the Donation of Constantine as a fake, confirmed by Lorenzo Valla a few years later, and revealed the forgery of the Pseudo-Isidorian Decretals . He made friends with the Austrian astronomer Georg von Peuerbach and advocated a reform of the Julian calendar and the Easter computus, which, however, was not realized until the introduction of the Gregorian calendar in 1582.

Elector of Trier Prince-Elector of the Holy Roman Empire

The Elector of Trier was one of the Prince-Electors of the Holy Roman Empire and, in his capacity as archbishop, administered the archdiocese of Trier. The territories of the electorate and the archdiocese were not, however, equivalent.

Canon (priest) Ecclesiastical position

A canon is a member of certain bodies subject to an ecclesiastical rule.

A dean, in a church context, is a cleric holding certain positions of authority within a religious hierarchy. The title is used mainly in the Anglican Communion, the Roman Catholic Church, and many Lutheran denominations. A dean's assistant is called a subdean.

After the Archbishop Otto of Trier had died in 1430, Pope Martin V appointed the Speyer bishop Raban of Helmstatt his successor. Nevertheless, the Electorate was contested by opposing parties, and in 1432 Nicholas attended the Council of Basel representing the Cologne dean Ulrich von Manderscheid, one of the claimants, [4] who hoped to prevail against the new Pope Eugene IV. Nicholas stressed the determining influence of the cathedral chapter and its given right to participate in the succession policy, which even places the pope under an obligation to seek a consent. His efforts were to no avail in regard to Ulrich's ambitions; however, Nicholas' pleadings earned him a great reputation as an intermediary and diplomat. While present at the council, he wrote his first work, De concordantia catholica (The Catholic Concordance), a synthesis of ideas on church and empire balancing hierarchy with consent. This work remained useful to critics of the papacy long after Nicholas left Basel. [5]

Pope Martin V pope

Pope Martin V, born OttoColonna, was Pope from 11 November 1417 to his death in 1431. His election effectively ended the Western Schism (1378–1417).

Council of Florence 17th ecumenical council

The Seventeenth Ecumenical Council of the Roman Catholic Church was convoked as the Council of Basel by Pope Martin V shortly before his death in February 1431 and took place in the context of the Hussite wars in Bohemia and the rise of the Ottoman Empire. At stake was the greater conflict between the Conciliar movement and the principle of papal supremacy.

Initially as conciliarist, Nicholas approached his university friend Cardinal Julian Cesarini, who had tried to reconcile pope and council, combining reform and hierarchic order. Nicholas supported transfer of the council to Italy to meet with the Greeks, who needed aid against the Ottoman Turks. He arbitrated in the conflict with the Hussites. Between the summer of 1437 and early 1438 he was a member of the delegation sent to Constantinople with the pope's approval to bring back the Byzantine emperor and his representatives to the papally summoned Council of Florence of 1439, which was attempting to bring the Eastern Orthodox Church into union with the Western Catholic Church. The reunion achieved at this conference turned out to be very brief. Nicholas would later claim (in the postfaced dedicatory letter of On Learned Ignorance, which Nicholas finished writing on 12 February 1440) that he had chosen to write on this metaphysical topic because of a shipboard experience of divine illumination while on the ship returning from this mission to Constantinople.

After a successful career as a papal envoy, he was made a cardinal by Pope Nicholas V in 1448 or 1449. In 1450 he was both named Bishop of Brixen, in Tyrol, and commissioned as a papal legate to the German lands to spread the message of reform. This latter role, his 'Great Legation' of 1450–1452, involved travel of almost 3000 miles, preaching, teaching and reforming. He became known as the "Hercules of the Eugenian cause." [6] His local councils enacted reforms, many of which were not successful. Pope Nicholas canceled some of Nicholas' decrees, and the effort to discourage pilgrimages to venerate the bleeding hosts of Wilsnack (the so-called Holy Blood of Wilsnack) was unsuccessful. His work as bishop between 1452 and 1458 – trying to impose reforms and reclaim lost diocesan revenues – was opposed by Duke Sigismund of Austria. The duke imprisoned Nicholas in 1460, for which Pope Pius II excommunicated Sigismund and laid an interdict on his lands. Nicholas of Cusa returned to Rome, but was never able to return to his bishopric.

He died at Todi in Umbria on 11 August 1464. Sigismund's capitulation came a few days after Nicholas's death. [7]

Upon his death, Cusanus's body was interred in the church of San Pietro in Vincoli in Rome, probably near the relic of Peter's chains; but it was later lost. His monument, with a sculpted image of the cardinal, remains. Two other tombstones, one medieval and one modern, also are found in the church. In accordance with his wishes, his heart rests within the chapel altar at the Cusanusstift in Kues. To this charitable institution that he had founded he bequeathed his entire inheritance; it still stands, and serves the purpose Nicholas intended for it, as a home for the aged. The Cusanusstift also houses many of his manuscripts.


Nicholas of Cusa was noted for his deeply mystical writings about Christianity, particularly on the possibility of knowing God with the divine human mind – not possible through mere human means – via "learned ignorance." Cusanus wrote of the enfolding of creation in God and their unfolding in creation. He was suspected by some of holding pantheistic beliefs, but his writings were never accused of being heretical. [8] Physicist and philosopher Max Bernhard Weinstein wrote that Nicholas was, to a certain extent, a Pandeist. [9] Nicholas also wrote in De coniecturis about using conjectures or surmises to rise to better understanding of the truth. The individual might rise above mere reason to the vision of the intellect, but the same person might fall back from such vision.

Theologically, Nicholas anticipated the profound implications of Reformed teaching on the harrowing of Hell (Sermon on Psalm 30:11), followed by Pico della Mirandola, who similarly explained the descensus in terms of Christ’s agony.

Science and mathematics

Most of Nicholas of Cusa's mathematical ideas can be found in his essays, De Docta Ignorantia (Of Learned Ignorance), De Visione Dei (On the Vision of God) and On Conjectures. He also wrote on squaring the circle in his mathematical treatises.

From the Catholic Encyclopedia (1913 edition):

The astronomical views of the cardinal are scattered through his philosophical treatises. They evince complete independence of traditional doctrines, though they are based on symbolism of numbers, on combinations of letters, and on abstract speculations rather than observation. The earth is a star like other stars, is not the centre of the universe, is not at rest, nor are its poles fixed. The celestial bodies are not strictly spherical, nor are their orbits circular. The difference between theory and appearance is explained by relative motion. Had Copernicus been aware of these assertions he would probably have been encouraged by them to publish his own monumental work. [10]

Like Nicole Oresme, Nicholas of Cusa also wrote about the possibility of the plurality of worlds. [11] [12]

Norman Moore tells us in The Fitz-Patrick Lectures of 1905:

In medicine he introduced an improvement which in an altered form has continued in use to this day. This improvement was the counting of the pulse which up to his time had been felt and discussed in many ways but never counted. ...Nicholas of Cusa proposed to compare the rate of pulses by weighing the quantity of water run out of a water clock while the pulse beat one hundred times. ...The manufacture of watches with second-hands has since given us a simpler method of counting, but the merit of introducing this useful kind of observation into clinical medicine belongs to Nicholas of Cusa. [13]


In 1433, Nicholas proposed reform of the Holy Roman Empire and a method to elect Holy Roman Emperors. Although it was not adopted by the Church, his method was essentially the same one known today as the Borda count, which is used in many academic institutions, competitions, and even some political jurisdictions, in original form and a number of variations. His proposal preceded Borda's work by over three centuries. [14]

Nicholas' opinions on the Empire, which he hoped to reform and strengthen, were cited against papal claims of temporal power in the sixteenth and seventeenth centuries. Protestant writers were happy to cite a cardinal against Rome's pretensions. Protestants, however, found his writings against the Hussites wrong. Nicholas seemed to Protestants to give the church too much power to interpret Scripture, instead of treating it as self interpreting and self-sufficient for salvation, the principle of sola scriptura. [15]

Nicholas' own thought on the church changed with his departure from Basel. He tried arguing that the Basel assembly lacked the consent of the church throughout the world, especially the princes. Then he tried arguing that the church was unfolded from Peter (explicatio Petri). [16] This allowed him to support the pope without abandoning ideas of reform. Thus, he was able to propose to Pius II reform of the church, beginning with the pope himself. Then it was to spread through the Roman curia and outward throughout Christendom. [17]

Nicolas of Cusa noted that government was founded on the consent of the governed:

Accordingly, since by nature all men are free, any authority by which subjects are prevented from doing evil and their freedom is restrained to doing good through fear from penalties, comes solely from harmony and from the consent of the subjects, whether the authority reside in written law or in the living law which is in the ruler. For if by nature men are equally strong and equally free, the true and settled power of one over the others, the ruler having equal natural power, could be set up only by the choice and consent of the others, just as a law also is set up by consent. [18] [19]

Nicholas and other religions

Shortly after the Fall of Constantinople in 1453, Nicholas wrote De pace fidei, On the Peace of Faith. This visionary work imagined a summit meeting in Heaven of representatives of all nations and religions. Islam and the Hussite movement in Bohemia are represented. The conference agrees that there can be una religio in varietate rituum, a single faith manifested in different rites, as manifested in the eastern and western rites of the Catholic Church. The dialog presupposes the greater accuracy of Christianity but gives respect to other religions. [20] Less irenic but not virulent, is Cusanus' Cribratio Alchorani, Sifting the Koran, a detailed review of the Koran in Latin translation. While the arguments for the superiority of Christianity are still shown in this book, it also credits Judaism and Islam with sharing in the truth at least partially. [21]

Cusanus' attitude toward the Jews was not always mild; on 21 September 1451 he ordered that Jews of Arnhem were to wear badges identifying them as such. The De pace fidei mentions the possibility that the Jews might not embrace the larger union of una religio in varietate rituum, but it dismisses them as politically insignificant. This matches the decrees from Cusanus' legation restricting Jewish activities, restrictions later canceled by Pope Nicholas V. [22]


Nicholas was widely read, and his works were published in the sixteenth century in both Paris and Basel. Sixteenth-century French scholars, including Jacques Lefèvre d'Étaples and Charles de Bovelles, cited him. Lefèvre even edited the Paris 1514 Opera. [23] Nonetheless, there was no Cusan school, and his works were largely unknown until the nineteenth century, though Giordano Bruno quoted him, while some thinkers, like Gottfried Leibniz, were thought to have been influenced by him. [24] Neo-Kantian scholars began studying Nicholas in the nineteenth century, and new editions were begun by the Heidelberger Akademie der Wissenschaften in the 1930s and published by Felix Meiner Verlag. [25] In the early twentieth century, he was hailed as the "first modern thinker," [26] and much debate since then has centered around the question whether he should be seen as essentially a medieval or Renaissance figure. Societies and centers dedicated to Cusanus can be found in Argentina, Japan, Germany, Italy and the United States. His well-known quote about the infinity of the universe is found paraphrased in the Central Holy Book of the Thelemites, The Book of the Law, which was "received" from the Angel Aiwass by Aleister Crowley in Cairo in April 1904: "In the sphere I am everywhere the centre, as she, the circumference, is nowhere found."

In The Pursuit of God (1948), A.W. Tozer refers to Nicholas as someone who had a vibrant Christian spirituality, stating in Chapter 7, "I should like to say more about this old man of God. He is not much known today anywhere among Christian believers, and among current Fundamentalists he is known not at all. I feel that we could gain much from a little acquaintance with men of his spiritual flavor and the school of Christian thought which they represent…."

The Brethren of the Common Life was a Roman Catholic pietist religious community founded in the Netherlands in the 14th century by Gerard Groote, formerly a successful and worldly educator who had had a religious experience and preached a life of simple devotion to Jesus Christ. Without taking up irrevocable vows, the Brethren banded together in communities, giving up their worldly goods to live chaste and strictly regulated lives in common houses, devoting every waking hour to attending divine service, reading and preaching of sermons, labouring productively, and taking meals in common that were accompanied by the reading aloud of Scripture: "judged from the ascetic discipline and intention of this life, it had few features which distinguished it from life in a monastery", observes Hans Baron.

Conciliarism was a reform movement in the 14th-, 15th- and 16th-century Catholic Church which held that supreme authority in the Church resided with an Ecumenical council, apart from, or even against, the pope. The movement emerged in response to the Western Schism between rival popes in Rome and Avignon. The schism inspired the summoning of the Council of Pisa (1409), which failed to end the schism, and the Council of Constance (1414–1418), which succeeded and proclaimed its own superiority over the Pope. Conciliarism reached its apex with the Council of Basel (1431–1449), which ultimately fell apart. The eventual victor in the conflict was the institution of the Papacy, confirmed by the condemnation of conciliarism at the Fifth Lateran Council, 1512–17. The final gesture however, the doctrine of Papal Infallibility, was not promulgated until the First Vatican Council of 1870.

During Pius II's pontificate, Balbi was the most prolific translator of Greek patristics in Rome, probably using the Greek manuscripts in Bessarion's own library. One of the quattrocento defenders of Plato, he translated for Cusanus the epitome of Platonic Philosophy, Disciplinarium Platonis epitome, of the 2nd-century philosopher Albinus and the immense Theologica Platonica of Proclus in 1462, and circulated it in manuscript. Giovanni Andrea Bussi printed his translation of Alcinous, and Cusanus cast Balbi and Bussi as interlocutors in his dialogue De lì non aliud in the winter of 1462.
