One Soul To Guide Them All

Averroes (1126-1198) undertook to explain and comment on the works of Aristotle, in an attempt to clarify the Greek philosopher's concepts. One of those concepts was the idea of man's intellect, the debate over which was both stimulating and shocking for the medieval world.

Averroes (in turban); detail, "School of Athens" (Raphael)

Aristotle distinguished between a passive intellect, which is man's predisposition to accept and hold ideas, and an active intellect, which was the agent of analysis and creativity.* The active intellect was an outside force, and the blending or convergence of the external active intellect with the internal passive intellect differed in individuals, which is why we could strive to learn and think and better ourselves intellectually, but we were still different from each other. The connection between active and passive was not the same in each person. This accounted for different and individual personalities.

This was an obvious parallel to Aristotle's Realism: the idea that there exist "universal" abstract concepts—such as "dog"—outside of our direct experience, that allow us to directly experience multiple different dogs with different characteristics (which he called "particulars") and yet understand that they were all dogs.

Averroes explained this further, and created a religious controversy.

If the active intellect was external (and from a divine source) but the less-powerful passive intellect resided in man, and it was the blending of the two that created personality and human intelligence, then what happens at death when the external active intellect is removed? As a divine and lasting and (presumably) unchanging force, it stays as it is, unaffected by its temporary connection to an individual. The human-centered passive intellect dies with the human, the active intellect withdraws, and therefore there is no individual personality that exists anymore.

For Averroes, understanding Aristotle meant that there was no survival after death of a personality. Your personality—what makes you "you"—is gone when you die, and there is no room here for a soul with your personality to exist in an afterlife.

Orthodox Mohammedan theology did not agree with this, nor did Christian theologians such as St. Bonaventure and St. Thomas Aquinas.

Averroes defense against the charge of heresy? That reason forced him to express these thoughts, but that of course he adhered to the truth as explained by his faith.

*Aristotle used the term "intelligences" to refer to the non-physical (divine, or spiritual) forces that moved the celestial spheres. Christian thinkers would later call these "angels."

Nominalism vs Realism

Realism [link]

At the foundation of philosophy is a question: what defines reality? There are several questions that are connected to this. Let us start with: when we say that a lot of different animals are all dogs, to what quality are we referring that makes the Dachsund and the Great Dane both dogs? Is there an essential quality of "dog-ness"? Some universal concept that is inclusive of all dogs, despite the particular differences between breeds?

There it is: universals and particulars.

Realism says that both universals and particulars exist. That is, we recognize that different dogs/houses/trees are those things because, although they have different particulars, there is a universal essence of dogs/houses/trees that exists. Plato and Aristotle were Realists.

Nominalism says that the world is made only of particulars. Things we see are put into categories by our thought processes and our language, not by the existence of some abstract universal. William of Ockham and Jean Buridan were Nominalists.

In the two diagrams shown, we see that in Realism, although John and David have different Particulars, they are defined by their Universal quality as human beings. Nominalism, however, shows John and David only defined by their Particulars. The category of Humanity is created by us. There is no abstract "Humanity" essence that exists independent of John and David.

Nominalism [link]

Getting at the truth produced some fascinating thought experiments. One—The Puzzle of Theseus' Ship—was posed by Plutarch (46-120 CE). The ship of Theseus was preserved in Athens for several generations. As pieces of it decayed, they were replaced with new wood, so that the ship would stay intact. If a thing is based on its particulars, then with the particulars of this ship having changed over the years, is it still Theseus' ship? If there is some universal of Theseus' ship (as Realism says) then it is still his ship. If there are only particulars (as Nominalism says) then it isn't.

British philosopher Thomas Hobbes (1588-1679) took this a step further: if all the removed pieces were assembled into a complete ship, then which is Theseus' ship? Are they both Theseus' ship? He concludes that this would be absurd.

Even the early scholars understood that there were problems with these concepts, and struggled to reconcile the issues. Still, they did their best to understand how reality worked, and how that would help them to understand everything else.

...such as whether we have individual souls. That discussion will take us back to Averroes tomorrow.

And then, Champagne

William of Champeaux (c.1070-1122) was a student of Anselm of Laon, and may have helped to compile the Glossa interlinearis. He may also have been born many years earlier than the date assumed, since he was appointed Master of Notre Dame in 1094, and 24 years old would have been a very young Master to handle some of the issues of the day. He taught at the cathedral school of Notre Dame, and like Anselm was a proponent of Realism.

A medieval university lecture

He also may have studied under the Nominalist Roscellinus of Compèigne. The Nominalists believed that universal/abstract concepts of Realism (which existed independent of our perceptions of things (think of Plato's myth of the cave) did not exist. Instead, there are only particular things: there is this chair and that chair, but no universal and abstract chair from which your and my chair derive. Words were either significant or made up. A significant word was intimately connected with the concept it described. Examples of words that are not significant are "chimaera" and "blictrix" and "hircocervus" because they are not real things. The extension of this approach leads to difficulties, because (as we know) we can talk about things that are untrue.

William, however, rejected Nominalism. He and Anselm of Laon were Realists. William is considered by some to be the founder of an extreme form of Realism, perhaps as a result of refining his views during debates with Peter Abelard.

One of the most famous students in Paris was Peter Abelard, more of whose writings have survived and been widely read than William's. Abelard debated with William numerous times over these concepts and others. Although Abelard (according to his own biographical work) lost every time, he calls William a jealous and defeated and discredited man, and claims that William was driven from the Paris schools. Even so, Abelard followed William in order to study under him further, which may be more telling than Abelard's criticisms of a man to whom he lost several arguments.

It is true that William left Paris. He went to the Abbey of St. Victor just outside of Paris. Two of his students from this time were Hugh of St. Victor and Bernard of Clairvaux, both of whom would greatly distinguish themselves. William continued to gain the attention of his superiors, as well, who moved him wherever they felt the need for a calm head and a devout reformer.

...and then, Champagne.

Champagne is a sparkling wine produced via a secondary fermentation in the bottle that produces carbonation. It is properly only made from grapes grown in the Champagne Valley region in northeast France, the boundaries of which are determined by law. This Champagne wine was first made notable when it was used at special occasions such as French coronation festivities. It was William in 1114, in his capacity as bishop of Chalons-sur-Champagne, who issued the Grande charte champenoise (Great Champagne Chart). This "defined the agricultural and viticultural possessions of the Abbey of Saint-Pierre-aux-Monts, thus giving rise to the modern Champagne wine region." [reference] Although the boundaries since then have been amended a few times, it was William of Champeaux, extreme Realist and theologian, who first determined what could rightly be called "champagne."

*I apologize for not being better at explaining philosophical concepts; also, I do not even want to try to get into more detail, lest I get us both bogged down.

Anselm of Laon Explains the Bible

Anselm of Laon (d.15 July 1117) studied under one of the great names of the day, St. Anselm of Bec, whom I teased about here. He became a master of the new scholastic theology, and helped establish two schools of theology and created a new way to read the Bible.

Scholastic theology was a blend of two traditions: patristic learning (that is, writings from the fathers of the early church, such as Augustine), and the reasoning skills derived from reading the non-Christian thinkers such as Greek philosophers and Jewish scholars (which at this point were usually available because of Islamic scholars). The Scholastics were no longer content to shake their heads and simply accept apparent inconsistencies in the Bible. Their goal was to order and understand the entire world, and that meant first understanding the Bible.

17th century edition of Anselm's Bible

Consequently, Anselm produced an edition of the Bible called the Glossa interlinearis, so-called because his commentary was written above or next to each line.* Anselm's work was groundbreaking in that it presented a discussion and explanation for the Bible in an easily accessible manner, verse by verse.

His other notable contribution to theology was at the university in Paris, which he co-founded with William of Champeaux. Here theologians promoted Realism, the philosophy that our reality is independent of our beliefs, perceptions, and language. For Realists, truth is understood as one learns of and conforms to reality.

Anselm of Laon became so well-known for his understanding of theology that, when he moved to Laon to start a school there, scholars traveled to study with him. One of these, Peter Abelard, would be expelled from the school by Anselm in 1113 after debates over the validity of Realism, but would go on to become, in his turn, one of the groundbreaking theologians of the next generation. Anselm, though not well known now, would have been happy to know that his glosses on the Bible were re-printed several times over the following centuries.

*Modern scholars think it more likely that the Glossa was compiled by Anselm's students after his death, using Anselm's lectures and (now lost) writings.  This was one of two chief commentaries on the Bible. The other was the Glossa ordinaria of Walafrid Strabo (808-849).
