Theologians
Thomas Aquinas (Italian: Tommaso d'Aquino, also called Aquinas, alias Doctor Angelicus) was an Italian poet and theologian, philosopher, and major medieval scholastic.
Thomas Aquinas is one of the most important theologians in the history of Western civilization, given the extent of his influence on the development of Roman Catholic theology since the fourteenth century. As a theologian, in his two masterpieces, Summa theologiae and Summa contra gentiles, he created the classical systematization of Latin theology, and as a poet, he wrote some of the most serious and beautiful Eucharistic hymns in the church liturgy. Thomas Aquinas is recognized by the Roman Catholic Church as the foremost Western philosopher and theologian and canonized as a saint.
Cornelius Gerardi Aurelius, also called Goudanus, was a Dutch humanist scholar, writer, and historian.
Aurelius was a permanent canon (monk) of the Augustinian monastic order and is one of the first humanists of the Netherlands in the 16th century. He wrote poetry, historiography, hagiography, political and theological works. Aurelius also corresponded with many of the famous men of his day, especially Erasmus.
Jacques Basnage de Beauval was a French theologian and historian, diplomat and writer.
His father was a prominent lawyer and his grandfather and great-grandfather were pastors, Jacques studied theology and languages at the Academy of Saumur, then at Geneva and Sedan. In 1676, Jacques Basnage was appointed pastor at Rouen during the revocation of the Edict of Nantes, was forced to flee France for Holland, where he worked as a theologian, polemicist, historian, and diplomat in the service of the Grand Pensioner Hensius.
In 1717, on behalf of Holland, Basnage was sent to sign the treaty of the Triple Alliance (France, Holland, England). In the Annals of the United Provinces (1719-1726), compiled from the peace negotiations held at Münster, he displays breadth of vision, wisdom, and impartiality.
About 1719 Jacques Basnage was appointed historiographer of the Dutch states. He wrote several books on the Bible, the history of the Church, and the history of the Jewish people. Among the best known of these are his History of the Religion of the Protestant Denominations (1690), History of the Church of Jesus Christ to the Present Time (1699), written from Protestant positions, and History of the Jews (1706), as well as Jewish Antiquities, or Critical Notes on the Republic of the Jews (1713).
Pierre Bersuire, also known as Petrus Berchorius, was a French medieval writer, Benedictine monk, translator, and encyclopedist.
He was the leading French scholar of his time and friend of Petrarch, author of encyclopedic works on morality, and the first French translator of Titus Livy's History from the Foundation of the City. Very interesting for researchers is Pierre Bersuir's text Ovidius Moralisatus - written in Avignon in 1340 and spreading rapidly, it is a systematic allegorical analysis of the Metamorphoses, aimed at the current situation in church and society.
Bersuire was also an eloquent preacher and author of voluminous sermons.
Bernard Bolzano, full name Bernard Placidus Johann Nepomuk Bolzano, was an Italian-born Czech scientist, mathematician, logician, philosopher and theologian.
Bolzano graduated from the University of Prague and was immediately appointed professor of philosophy and religion at the university. Within a few years, however, Bolzano had already shown himself to be a free thinker with his teachings on the social costs of militarism and the needlessness of war. He called for a complete reform of the educational, social, and economic systems that would direct the nation's interests toward peace rather than armed conflict between states. In 1819, Bolzano was expelled from the university for his beliefs and thereafter turned his full attention to works on social, religious, philosophical, and mathematical issues.
Bolzano held advanced views on logic, mathematical quantities, limits, and continuity. He is the author of the first rigorous theory of real numbers and one of the founders of set theory. In his studies of the physical aspects of force, space, and time, he proposed theories opposed to those advanced by the German philosopher Immanuel Kant. His contributions to logic, in particular, established his reputation as the greatest logician of his time. Much of his work remained unpublished during his lifetime and was not widely disseminated until the late nineteenth and early twentieth centuries, when a number of his conclusions were reached independently.
Bolzano was multi-talented in various fields of science to which he made significant contributions. His published works include The Binomial Theorem (1816), A Purely Analytic Proof (1817), The Functional Model and the Scientific Model (1834), An Attempt at a New Statement of Logic (1837), and The Paradoxes of Infinity (1851).
Among other things, Bolzano was also a great philanthropist. Together with his friends and students, he supported the activities of almshouses, homes for the blind, loan banks for the working class, libraries, and elementary schools in rural areas.
Otto Brunfels (also Brunsfels, Braunfels) was a German theologian, botanist and physician.
After studying theology and philosophy at the University of Mainz, Brunfels went to a Cartesian monastery near Strasbourg and later became interested in botany there. 1524 he opened a school in Strasbourg. In 1530, Brunfels began studying medicine at the University of Basel and two years later became city physician in Bern, where he remained for the rest of his life.
In addition to theological works, Brunfels published works on education, Arabic, pharmacy, and botany. His Herbarium Vivae Icones (1530 and 1536) and Contrafayt Kreüterbuch (1532-1537) contain woodcuts of German plants with their German common names. The 135 original woodcuts are detailed, accurate, and realistic depictions of living plants by the German artist and engraver Hans Weiditz. Brunfels' work contributed to the shift away from medieval outdated herbalism to the establishment of botany as a modern science. Carl Linnaeus considered Brunfels one of the founders of modern botany.
Johannes Busch was a major Dutch clergyman and reformed theologian.
As a monastic reformer and chronicler, the Augustinian canon of Windesheim, Johannes Busch is one of the most prominent figures of the Devotio moderna ("New Piety") movement in Catholicism. With his historiographical works Chronicle of the Monastery of Windesheim and Liber de reformatione monasteriorum he shaped the association of the Windesheim monastery and the late medieval observance movement.
Étienne Chauvin was a French Protestant theologian and philosopher.
Chauvin's philosophy and worldview were entirely Cartesian. After his expulsion from Nîmes, Étienne Chauvin withdrew to Rotterdam, where he preached for several years in the Walloon Church. He was succeeded as professor of Baille at Rotterdam. In 1695 the Elector of Brandenburg appointed him pastor and professor of philosophy, and afterward inspector of the French college at Berlin.
Etienne Chauvin's major work is Lexicon Rationale, sive Thesaurus Philosophicus (1692). He also wrote Theses on the Knowledge of God (1662) and published the New Journal of Scholars (1694-1698).
Jean Charlier de Gerson was a French academic, theologian, preacher and politician of the 14th and 15th centuries.
Jean Charlier de Gerson was Chancellor of the University of Paris from 1395 until 1415, and as such played a major role in the political troubles between the Duke of Orleans and the Duke of Burgundy, subsequently known as the Armagnacs and Burgundians, as well as in the crisis arising from the Great Western Schism.
Nicolas-Louis De la Caille was a French astronomer, abbot and educator.
He studied philosophy and theology, became an abbot, but the craving for science overpowered everything, and he studied astronomy on his own. In 1736, la Caille received a place at the Paris Observatory, in 1739 was appointed professor of mathematics at Mazarini-College in Paris and built his own observatory, where he conducted astronomical observations. In 1741 Lacaille was admitted to the Académie des Sciences.
La Caille was an outstanding astronomer: he observed more than 10,000 stars in the Southern Hemisphere and named 14 of the 88 constellations. In 1752, he made an astronomical expedition to the Cape of Good Hope, where he built an observatory and conducted a huge series of observations, including the discovery and cataloging of 42 nebulae. These studies led to la Caille being called "the father of southern astronomy," and his observations from South Africa of the Moon, Venus, and Mars, combined with similar observations already made in the Northern Hemisphere, led to the calculation of more accurate values for the distances to these bodies.
On his return to Paris two years later, in 1754, he resumed his post and taught at the school of Mazarin, continuing his work at the observatory of the College of Mazarini. Among his pupils was the great chemist Antoine Lavoisier. La Caille was a foreign honorary member of the St. Petersburg Academy of Sciences and a member of the Royal Society of London. His Coelum Australe Stelliferum ("Star Catalog of the Southern Sky") was published in 1763.
Benedictus Spinoza (Spanish: Baruj Espinosa) at birth Baruch Spinoza is a Dutch philosopher-rationalist of Jewish origin, a bright representative of the Age of Enlightenment.
Spinoza was born into a family of Portuguese Jews in Amsterdam, who converted to Christianity but returned to Judaism. As a young man, he was considered an outstanding Talmudic scholar and a promising religious scholar. But, inspired by the philosophical writings of René Descartes and Francis Bacon, the young philosopher soon fell outside the orthodox tradition because of his radical views. In 1656 he was severely excommunicated for heresy.
For the rest of his life, Spinoza spent his modest life grinding lenses and privately teaching philosophy, but he also wrote anonymously published philosophical treatises and secretly exchanged letters with many philosophically inclined luminaries of the wider European Enlightenment. Spinoza's only book, published in 1663 in Amsterdam under his own name, was Renati Des Cartes Principiorum Philosophiae Pars I, & II, More Geometrico demonstrate (Principles of Cartesian Philosophy). These principles served as a preparatory work for many metaphysical views in his most important treatise, Ethics (1677).
Benedict Spinoza defended the philosophical life from religious persecution and advocated a new, liberal, democratic regime to support that life. Although Spinoza was often persecuted as an atheist in his time, his writings played an important role in shaping philosophy, theology, and politics in the centuries to come. Of all the philosophers of the seventeenth century, Spinoza is one of the most relevant today.
Jacopo Filippo di Bergamo, or Giacomo Filippo Forèsti (Latin: Iacobus Philippus Bergomensis) was an Italian Augustinian monk, theologian and chronicler.
Jacopo di Bergamo was born into a noble family, received his ecclesiastical education at the local monastery, and early showed a penchant for literary work. After traveling in Europe, he took the tonsure and was abbot of monasteries, engaged in their improvement.
He is known as the author of a number of significant early printed works, a chronicler and biblical scholar. His Supplementum chronicarum (1483) is a universal chronicle that survived many subsequent editions. And De claris mulieribus, published in 1497, contains the first account of the voyage of the discoverer Columbus.
Ralph Waldo Emerson was an American philosopher, lecturer and poet, one of the most prominent thinkers and writers in the United States, and the originator of transcendentalism.
Ralph studied at Boston State Latin School and then at Harvard College (later Harvard University), began to preach, but soon doubted his chosen path and resigned his ministry. Emerson went to Europe, where new acquaintances and knowledge led him to new thoughts, and, returning to the United States in 1833, he began writing his famous book "Nature", where he first formulated a philosophy called transcendentalism. Soon other thinkers rallied around him, forming a group of like-minded thinkers.
In the essay "Nature," published in 1836, and in the following works, "The American Scholar" and "An Address in the School of Theology," Emerson consistently developed his ideas. Emerson's doctrine of the self-sufficiency and self-reliance of the individual stems from his view that a person need only look into his own heart to receive the spiritual guidance that has hitherto been the prerogative of the official churches. One must then have the courage to be oneself and trust the inner power within oneself, living one's life according to the commandments one has intuitively derived. These thoughts are not new, but Emerson put them in imaginative and accessible language.
Emerson's speeches led to his being ostracized at Harvard for many years. However, the informal Transcendental Club, founded in 1836, was joined and supported by his young students. The world fame of the brilliant thinker Emerson brought his "Essays" in two volumes, published in 1841 and 1844. As the main representative of transcendentalism, Emerson gave direction to the religious, philosophical and ethical movement, which above all emphasized belief in the spiritual potential of each person.
A later work of confession, The Conduct of Life (1860), demonstrates the author's developed humanism and full awareness of human limitations. The voluminous collection of poems cemented Emerson's reputation as a major American poet.
Francis Junius the Elder, born François du Jon, was a French linguist, exegete and professor of Reformed theology, and diplomat.
Junius first studied law and then theology and became a student of Jean Calvin and Theodore Beza in Geneva. For his success and knowledge of languages he was appointed minister at Antwerp, but was forced to flee to Heidelberg in 1567.
In collaboration with Immanuel Tremellius he wrote one of the significant translations of the Bible into Latin, and his theological work De Vera Theologia is the most important work on Reformed dogmatics. Some of du Jon's works were published in 1882 by Abraham Kuyper in his Reformed Library. His son François du Jon the Younger (1591 - 1677) became a noted art historian and founder of Germanic philology.
Martin Luther King Jr, born Michael King, is an American preacher, leader of the Black Civil Rights Movement in the United States, and Nobel Laureate.
His father was the famous Baptist missionary and leader of the Civil Rights Movement Martin Luther King Sr. (1899-1984). He studied medicine and law at Morehouse College, then earned a bachelor's degree in theology at Crozer Theological Seminary in Pennsylvania, followed by a doctorate in theology at Boston University. And beginning in 1955, King Jr. became active in the community with protests over segregated seating on public buses.
On September 20, 1958, the first assassination attempt was made on Martin. Isola Ware Curry, a mentally unstable Harlem woman, stabbed King with a metal letter opener at a department store where he was signing copies of Stride Toward Freedom as part of a tour to promote the book.
Martin Luther King, Jr. was a driving force behind such watershed events as the Montgomery Bus Boycott and the 1963 March on Washington, which resulted in the historic Civil Rights Act (1964) and Voting Rights Act (1965). He was a prominent African American leader of the civil rights movement of the 1950s and 1960s. In 1964, Martin Luther King, Jr. was awarded the Nobel Peace Prize for his activism for civil rights and social justice. King also actively opposed the Vietnam War, calling for an end to the bombing, negotiations, and the withdrawal of U.S. troops.
On April 4, 1968, King was assassinated by gunfire on the balcony of the Lorraine Motel in Memphis. James Earl Ray, a petty criminal who had escaped from a maximum-security prison a year earlier, was blamed for the murder. Years after his death, Martin Luther King Jr. became the most famous African-American leader of his era. Today, he has a reputation as a visionary leader who was deeply committed to achieving social justice through nonviolent means. In 1983, President Ronald Reagan signed into law a U.S. federal day in King's honor; it is observed nationwide on the third Monday in January.
Marin Mersenne (also Marinus Mersennus or le Père Mersenne) was a French mathematician, physicist, philosopher and theologian, and music theorist.
Mersenne was educated at the Jesuit college of La Fleche and went on to study theology in Paris. He also became a member of the Order of the Minims and taught philosophy and theology at Nevers. He developed his ideas about the essence of the world and knowledge, insisting on the importance of experimentation and observation, and contrasted the rational natural world with human reason.
Beginning in 1635, Mersenne founded the Académie Parisienne, the forerunner of the French Academy of Sciences, where France's leading mathematicians and natural philosophers gathered. It provided a forum for the exchange of ideas among scientists and promoted the works of René Descartes and Galileo. The scientist's most famous achievement in mathematics was finding a formula for generating prime numbers, known today as Mersenne's Numbers. In 1644, Mersenne published his studies of Mersenne numbers and their relationship to prime numbers. His work in number theory and arithmetic proved pivotal to the development of mathematics in the seventeenth century.
He corresponded with many other scientists of the era, such as René Descartes, Blaise Pascal, and Pierre Fermat. However, his contributions extend much further, through his role in disseminating the work of the outstanding minds of his time. Mersenne traveled extensively throughout Europe, bringing new scientific ideas to France. He was an important mediator in the exchange of knowledge and contributed to the advancement of science in his era.
Joachim of Fiore, also known as Joachim de Fiore, and Gioacchino da Fiore, was an Italian mystic, theologian and philosopher of history, a great medieval thinker with a beautiful symbolic imagination.
Fiore was a prolific writer and explored the hidden meaning of the life of the apostles and the scriptures. At the end of the twelfth century Joachim had a high international reputation.

He retired to the mountains to lead a contemplative life, and in 1196 he founded the Order of San Giovanni in Fiore. In his Book of the Harmony of the New and Old Testaments, Fiore set forth a theory of history and traced correspondences in the Old and New Testaments. In "An Exposition of the Apocalypse" he explored the symbols of the Antichrist, and in "The Ten-String Psalter" he set forth his doctrine of the Holy Trinity. A man of vivid imagination, he was proclaimed a prophet and condemned as a heretic.
Augustine of Hippo (Latin: Aurelius Augustinus Hipponensis), also known as Saint Augustine, was a theologian and philosopher of Berber origin and the bishop of Hippo Regius in Numidia, Roman North Africa. His writings influenced the development of Western philosophy and Western Christianity, and he is viewed as one of the most important Church Fathers of the Latin Church in the Patristic Period.

Together with King James of Aragon and St. Peter Nolasco, he founded the Order of Our Lady of Ransom. The monks of this Order devoted themselves to saving Christians captured by the Moors. One of Raimondo of Peñafort's main goals was the conversion of Jews and Muslims to Christianity, and to achieve this goal he ordered Arabic and Hebrew to be studied and taught in the higher schools run by the Dominicans. He was also among those who founded the Inquisition in Catalonia.
Raimondo died at the age of 100 in Barcelona in 1275 and was canonized by Pope Clement VIII in the same year.
William of Rennes was a 13th-century French Roman Catholic monk, poet, theologian, and expert in canon law.
His commentaries and annotations on the works of the revered Catholic saint Raymond of Peñafort enjoyed almost equal authority in most manuscripts and early editions on academic theology and canon law. William of Rennes also wrote the epic of King Arthur, which is of interest to scholars of literature in that it was the first attempt to transform a medieval hero into a hero of classical eras.
Giovanni Vincenzo Petrini was an Italian priest and theologian, philosopher, mathematician, and expert in mineralogy.
Along with Scipio Breislacus, Petrini was one of the founders of Italian volcanology. He taught philosophy and mathematics, theology, but specialized in mineralogy and created the Mineralogical Cabinet in Nazareth. This museum was famous in Europe and was visited, among others, by Emperor Joseph II, who gave him rare specimens from the lands of the Empire and especially from Hungary.
Giovanni Petrini was the author of the catalog Gabinetto mineralogico del Collegio Nazareno ("The Mineralogical Cabinet of the Nazarene Collegium, described by external features and distributed by component parts" (Rome, 1791-1792). The specimens in it are classified according to a standard structure: salts, earths, bitumens, combustibles, and metals. There is also a section on gemstones.
