The 13th Century

Chapter XII - The 13th Century

The great men of the 13th century were:
1) Innocent III
2) St. Francis
3) Frederick II
4) Thomas Aquinas

Pope Innocent III reigned from 1198-1216. Innocent III was a shrewd politician and assured Papal supremacy in Sicily, Portugal and Aragon. After resistance, King John conceded England under Papal supremacy.

He destroyed the Albigenses, a heretical group in southern France. He "rooted out heresy, happiness, and culture from southern France" (Russell, 442).

He had Emperor Otto deposed by the German people.

"Innocent III was the first great pope in whom there was no element of sanctity" (Russell, 443).

He codified Canon Law, increasing the power of the Curia.

Frederick II became Emperor of the Holy Roman Empire through Innocent's endorsement. Innocent III would die before Frederick II assumed the position of a formidable antagonist to the Church.

Frederick II was the son of Henry IV and Constance (heir to the Sicilian throne). His childhood was marred with Sicilian wars with Muslims, Germans, Pisans, and Genoese.

The culture of Sicily was a combination of Arabic, Italian, Greek, Byzantine and German cultures.

Frederick II spoke six languages fluently and wittily. He was familiar with Arabic philosophy. He was a Hohenstaufen and could thus be considered German. He was culturally akin to Italians however.

Frederick II's problems with the papacy came when he refused to go on crusade. He was excommunicated later by Pope Gregory IX for not going on crusades and waging war in Lombardy.

He married the daughter of the King of Jerusalem and after the king's death calls himself the king of Jerusalem, infuriating the Pope. He integrated Muslims back into Jerusalem, thus further infuriating the Pope.

Eventually peace was restored between Emperor and Pope in 1230.

He systematized the laws of Sicily (where he was also king).

He founded an important university at Naples.

He freed up trade.

He was once again excommunicated in 1237 for waging war against the Lombards.

His successors after his death in 1250 were not as powerful and the Papacy absorbed power and Italy was left divided.

The heresies of the 13th century are important to study:

The Carthi or Albigenses were the largest sect of heresy at the time. They existed primarily in Northern Italy and Southern France. The Carthi were dualists. They regarded the Old Testament God as wicked. They regarded matter as evil. They believed that virtuous men had no resurrection of the body. They believed that the wicked would suffer transmigration into the bodies of animals. For this they were vegetarians, even abstaining from eggs, cheese, and milk. They ate fish because they did not think that fish reproduced sexually. They despised sex, even inside of marriage. They did not object to suicide. They interpreted the New Testament entirely literally. One who was persecuted offered his defense by claiming that he ate meat, lied and swore like any other good Catholic.

The genealogy of the Carthi is interesting. Carthi (from) Bogomiles (in Bulgaria) - a fusion of Manichaeans and Paulicians. The Manichaeans were founded by Mani and once had Augustine as a proponent.

The Paulicians were followers of Marcion. They were an Armenian sect. They rejected:
1) Infant baptism
2) Purgatory
3) The invocation of the saints
4) The Trinity
5) The Jewish elements of Christianity

The other important heresy of the 13th century were the Waldenses. They were followers of Peter Waldo.

Peter Waldo founded the "Poor Men of Lyons". They were originally papally sanctioned, but were condemned for condemning immorality in the clergy too vocally. They then split from the church.

They existed in Lombardy and Bohemia, eventually paving the way for Jan Hus. They still exist today in the Alpines and in the US.

Heresy was combatted by the Pope in founding the Inquisition in 1233 by Pope Gregory IX.

The Inquisition was mainly performed by the Dominican and Franciscans.

The Church was in danger of a revolt in the 13th century, but was saved by mendicant orders.

St. Francis of Assisi was born around 1181 and died in 1226. He was well-to-do, but later devoted himself to poverty, despite furious family members. Pope Innocent III recognized St. Francis' followers as an order around 1210. St. Francis was one of the most lovable men in History and a saint among saints. But after his death the Franciscans fell into a trap.

"If Satan existed, the future of the order founded by Saint Francis would afford him the most exquisite gratification" (Russell, 450). Linehan - this is an off-hand remark that is completely unnecessary to the conversation. It is another cheap shot by Russell.

The Franciscans became another wealthy order in the Church hierarchy after Francis' death. They took an active role in the Inquisition and suppression of free thought.

Saint Dominic (1170 - 1221) devoted himself to combatting heresy. He founded his order in 1215.

The Dominicans were even more active in the Inquisition. They were devoted to learning. Dominicans provided two great philosophers intent on reconciling Aristotle to Christ:
1) Albertus Magnus
2) Thomas Aquinas

The Franciscans produced three great philosophers:
1) Roger Bacon
2) Duns Scotus
3) William of Occam

Chapter 14 - Franciscan Schoolmen

The Franciscans and Dominicans were bitter rivals. The Franciscans were less orthodox. They were disinclined to accept the authority of Thomas Aquinas (a Dominican).

The Franciscans produced Roger Bacon, Duns Scotus, William of Occam, Saint Bonaventura and Matthew of Aquasparta.

Roger Bacon lived from 1214-1294. Bacon was a philosopher and a man of science. Science was mixed up with black magic and alchemy at the time so Bacon was in constant danger of being labeled a heretic. He was placed under a no-publish edict by the head of the Franciscans, but commanded by the papal legate to England to write his philosophy for the benefit o the Pope. He wrote three books in a very short time:
1) Opus Majus
2) Opus Minus
3) Opus Tertium

He was imprisoned for condemning clerics for ignorance. He was imprisoned 14 years and died shortly after being released. He was experimental by nature; encyclopedic but not systematic. He was a good geographer and a good mathematician. He thought logic was useless and wrote on alchemy.

He believed there were four causes for ignorance:
1) frail and unsuitable authority
2) influence of custom
3) the opinion of the unlearned crowd
4) the concealment of ignorance by apparent wisdom

All ignorance produces the evils that plague mankind. The fourth is the worst.

He considers Aristotle to be the chief philosopher and Avicenna the price.

He sees no fault in finding truth from the heathen and quotes Avicenna, Averroes, Alfarabi and Albumazar.

He sees mathematics as the only unrivaled source of certitude.

He believed that the intellect is separate from the soul.

Modern times praise Bacon because he places experimentation as a source of knowledge in higher esteem than argumentation as a source.

He believed in magic and astrology.

He is more respected now than he was in medieval times.

St. Bonaventura (1221-1274) was the General of the Franciscan order. He believed in the ontological argument for God. He believed in Platonic Ideas and saw Aristotelianism as in opposition to Christianity. He quoted Augustine extensively but ignored Pagan and Arab philosophies.

Matthew of Aquasparta (1235-1302) was a follower of Bonaventura. He opposed Aquinas from an Augustinian point of view. He quotes Aristotle, Avicenna, Anselm, the pseudo-dionysius and chiefly, Augustine.

He believed that Plato's ideas produce wisdom, but not knowledge and Aristotle produced knowledge but not wisdom. He sought to sync the two.

Duns Scotus (1270-1308) was Scottish and joined the Franciscans at Oxford University. He fought Aquinas on the immaculate conception and won the argument. He was Augustinian but less severe than other Franciscans.

Franciscans often disagreed with Aquinas because he was Aristotelian and the Franciscans were Platonic (through Augustine).

Scouts was a moderate realist, believed in Free Will and leaned somewhat to Pelagianism.

He held that there was no difference between being and essence.

He focused on evidence, things knowable without proof. There were three kinds of evidence:
1) Principles known by themselves
2) Things known by experience
3) our own actions

Without divine illumination no one can know anything.

He held the the principle of individuation (what makes one thing not identical with another) was due to form, not matter.

William of Occam is the second most important scholastic philosopher next to Aquinas. He lived circa 1290-1350. He was a pupil, then a rival of Scotus. He was excommunicated by Pope John XXII and took refuge with Emperor Louis (who was likewise excommunicated).

Dante (1265-1321) was an influential commentator in this age. Marsiglio of Padua (1270-1342) was a friend of William of Occham and a great political force of the time (in theory, not action). Marsiglio and William sought to preserve the Catholic faith, but fought against papal absolutism.

William's political works are done in a philosophical disputation style. William is best known for Occam's razor "it is vain to do with more what can be done with fewer" (Russell, 472).

In logic, William of Occam was a homilist.

He set to free logic and theory of knowledge from the basis of metaphysics and theology.

He holds that there are six metaphysical terms:
1) being
2) thing
3) something
4) one
5) true
6) good

He holds universals are things that can be predicated to many.

William of Occam believed perception to be the definition of knowledge.

His work encouraged scientific research.

After William of Occam there were no great scholastic philosophers.
