Cesare Cremonini, sometimes Cesare Cremonino (22 December 1550 – 19 July 1631), was an Italian professor of natural philosophy, working rationalism (against revelation) and Aristotelian materialism (against the dualist immortality of the soul) inside scholasticism. He signed his Latin texts Cæsar Cremoninus (and its genitive form Cæsaris Cremonini at the start of some titles), or Cæsar Cremonius.
Considered one of the greatest philosophers in his time, patronized by Alfonso II d'Este, Duke of Ferrara, corresponding with kings and princes who had his portrait, paid twice the salary of Galileo Galilei, he is now more remembered as an infamous side actor of the Galileo affair, being one of the two scholars who refused to look through Galileo's telescope.
- From 1573 to 1590 at the University of Ferrara. Starting at a very young age and considered a great talent, he obtained the patronage of Alfonso II d'Este, Duke of Ferrara (to whom he would dedicate his first major book in 1596). The jealousies caused by this protection helped him to eventually accept a position outside his native province.
- From 1591 until his death at the University of Padua in Padua, then under Republic of Venice rule (succeeding to Jacopo Zabarella), in a chair of natural philosophy and a chair of medicine.
He was so popular in his time that most kings and princes had his portrait and corresponded with him, sometimes consulting him about private and public affairs. At Padua, his salary was twice that of Galileo. He was especially popular among the French intellectuals who called him "le Cremonin" (the Cremonin); even a remote writer such as Jean-Louis Guez de Balzac mentioned him as "le grand Cremonin" (the great Cremonin) in his Lettres.
Metaphysical views 
Following up on the controversy opened in 1516 by Pietro Pomponazzi and continued by Jacopo Zabarella (his predecessors in the chair), Cremonini too taught that reason alone cannot demonstrate the immortality of the soul – his blind adherence to Aristotle implying that he believed in the mortality of the soul. After a paper he wrote about the Jesuits, and public statements he made in favor of laic teachers, the Jesuits in Venice accused him of materialism, then relayed their grievances to Rome. He was prosecuted in 1604 by the Inquisition for atheism and the Averroist heresy of "double truth", and ordered to refute his claims: as was his manner, Cremonini gently refused to retract himself, sheltering himself behind Aristotle's authority. Because Padua was then under tolerant Venetian rule, he was kept out of reach of a full trial.
As for the accusations, and beyond Cremonini's teachings: indeed his personal motto was "Intus ut libet, foris ut moris est" (Latin for "In private think what you wish, in public behave as is the custom"), which was taken by humanists as meaning that a scientific thinker could hold one set of opinions as a philosopher, and another set as a Christian; it was also adopted by European Libertines (brought back to France by his student and confidant Gabriel Naudé). After his death, Cremonini had his tombstone engraved with "Cæsar Cremoninus hic totus jacet" (Latin for "Here lies all of Cremonini"), implying that no soul survived.
His student Naudé (who had been his confidant for three months) qualified most of his Italian teachers as "Atheists" and especially Cremonini as a "déniaisé" ("one who has been wised up, unfoolish, devirginized", the Libertines' word for unbelievers); he added to his friends, translated, "The Cremonin, Professor of Philosophy in Padua, confessed to a few choice Friends of his that he believed neither in God, nor in Devil, nor in the immortality of the soul: yet he was careful that his manservant was a good Catholic, for fear he said, should he believe in nothing, that he may one morning cut my throat in my bed". Later, Pierre Bayle pointed out that Cremonini did not believe in the immortality of the soul (in the "Crémonin" article of his Historical and Critical Dictionary). Gottfried Leibniz, in his 1710 Theodicy, dealing with the Averroists, who "declared that man's soul is, according to philosophy, mortal, while they protested their acquiescence in Christian theology, which declares the soul's immortality", says "that very sect of the Averroists survived as a school. It is thought that Caesar Cremoninus, a philosopher famous in his time, was one of its mainstays". Pierre Larousse, in his opinionated Grand dictionnaire universel du XIXe siècle, stated Cremonini was not a Christian.
Cremonini and Galileo 
At Padua Cremonini was both a rival and a friend of his colleague Galileo. When Galileo announced that he had discovered mountains on the Moon in 1610, he offered Cremonini the chance to observe the evidence through a telescope. Cremonini, by then aware of the Inquisition's power, refused even to look through the telescope and insisted that Aristotle had definitely proved the Moon could only be a perfect sphere. When Galileo decided to move to Tuscany that year, Cremonini warned him that it would bring him under the Inquisition's jurisdiction. Indeed, the next year the Inquisition reviewed Cremonini's case for evidence against Galileo. Years later, in his book Dialogue Concerning the Two Chief World Systems, Galileo would include the character Simplicio, a dogmatic Aristotelian philosopher who was partly based on Cremonini.
Death and legacy 
When Cremonini died in 1631 during the Paduan outbreak of the Italian Plague of 1629-1631, more than 400 students were working with him. His previous students included, alphabetically:
- Theophilos Corydalleus, graduated 1613, a Greek philosopher, had a tremendous influence in the Greek-speaking world during the 17th and 18th centuries
- William Harvey, graduated 1602, an English doctor who was the first to correctly describe the circulation of the blood
- Joachim Jung, graduated 1619, a German mathematician and naturalist popularized by John Ray
- Ioannis Kottounios, an eminent Greek scholar and his successor to the chair of philosophy at Padua
- Giusto Lipsio, an Italian philosopher
- Gabriel Naudé, in 1625–27, a French scholar and Cardinal Mazarin's librarian
- Guy Patin, a French doctor, headmaster of the School of Medicine in Paris
- Antonio Rocco, an Italian philosophy teacher and libertine writer
- Corfitz Ulfeldt, in 1628–29, a famous Danish statesman and traitor
- Flemming Ulfeldt, also in 1628–29, a Danish statesman and military leader, younger brother of Corfitz
He was buried in the Benedictine monastery of St. Justina of Padua (to which he also willed his possessions). His name has been given to several streets ("via Cesare Cremonini" in Cento, "via Cesare Cremonino" in Padua) and an institute ("Istituto Magistrale Cesare Cremonini" in Cento).

Extended bibliography

As was the practice of the time, many of them are made of opuscules, separate treatises grouped in a single binding. (Please note that Latin title spelling can vary depending on their grammatical position in a sentence, such as a "tractatus" becoming a "tractatum" in the accusative case when inside a longer title.)

- Birth in 1550 is by far the most common date, but sometimes 1552 is found (inferred by some from the assertion that he started teaching at age 21 in 1573, see Pierre Bayle or ). Thus, some sources will say "ca. 1550", or "1550 or 1552".
