Theories of Vision and Light: Magic and Science

Tuesday, August 10th, 2010

First of all, it’s been a while since I had the time to post here. Ever since I started the full-time PhD, research has naturally taken precedence to my other interests. But, the Esoteric Coffeehouse blog has never been fully out of the picture and I’ve been thinking of ways to resuscitate it. Given my reduced amount of time available, I have decided that I will have to sacrifice some of the quantity of information that I can provide in this blog. Instead, the ‘new’ version of the Esoteric Coffeehouse will run shorter posts, perhaps with some pointers where to read further on some information. I also tend to make it more informal by providing more of my own thoughts and experiences on studying esotericism. Well, we’ll see how it goes.  

I’ve been looking at light and vision theories for the past week. As it turns out, up to the modern period there existed two main competing models: the ‘intromission’ and ‘extramission’ theory. The intromission is similar to the way we understand vision today: as light ‘entering’ our eyes and projecting the shape of perceived things within. This theory was supported mainly by Aristotelian and atomistic philosophers and was made an official part of science by Johannes Kepler. The extramission theory, on the other hand, was favoured by Pythagoras, Plato, Euclid, Galen and the Neoplatonists. According to it, the eyes ‘emit’ light, throwing ‘arrows’ that reflect one’s emotional state. Interestingly, this theory fits very well with the popular beliefs in the evil eye or love at first sight. In both cases, the onlooker projects his/her feelings of hate or love. The light emanation is imprinted within the soul of the person looked at.

Today, the triumph of science and its wholehearted adoption of the intromission theory has rendered the idea that eyes can project light obsolete. This is in fact ironic, since early mathematicians and physicists tended to support the extramission perspective, using Euclidean geometry to show how light projects outside the eye. However, interest in psychological phenomena has been challenging the official scientific perspective. The reality of the sense of being stared at from behind or through CCTV has been proven through empirical research by Rupert Sheldrake and others. Sheldrake is currently making the argument that the intromission theory should be revised. It would be interesting to think about the consequences of the idea that eyes may send forth rays of light and how that might affect our understanding of the ’superstitions’ of popular magic.

If you want to read more, Rupert Sheldrake’s articles are available on the web here and here. I also recommend David C. Lindberg’s scholarly studies, particularly Theories of Vision from al-Kindi to Kepler (1981), a preview of which can be found on Google Books.

Soft Technology, Alchemy and Escapism: A Critique of Avatar (I)

Thursday, January 14th, 2010

Happy New Year to all. Since it is the beginning of the year, I thought I’d experiment a little and write from time to time some commentaries on esoteric ideas related to popular culture. And what better way to start than with a review of the movie Avatar.

While I was watching Avatar, the concept of mundus imaginalis coined by historian and philosopher Henri Corbin kept crossing my mind in regards to the world of Pandora. Mundus imaginalis  is, simply put, the world of imagination – a world we project out of our mind. To us today this may be a poetic expression, but to traditional esoteric thought, this world was as real as we are, an intermediary place between this world and the divine one. It was a place we could access in our dreams and visions by the aid of a so-called ‘third eye’.

It is a phenomenon of our contemporary imagination to present this spiritual world as more accessible. What could make us transcend the barrier between our mundane universe and this magical one? The answer often is: technology. In Avatar, we see that technology (of a very expensive and sci-fi kind) can turn Jake Sully into an avatar capable of interacting with the world of imagination, symbolized by Pandora’s Navi people. We can see technology facilitating the forbidden interaction between the elusive Navi and the human beings.

But how does this apology for avatar technology reconcile with the explicit denial of technology amongst the idealistic Navis? After all, the Navis reject all complex machines and prefer hunting with spears and arrows. The movie’s answer is, by differentiating between ‘good’ technology and ‘bad’ technology. The good technology is the ‘soft’ kind: the one of computers and complex systems. It is this technology that allows one to ascend to the forbidden world of the Navis. Remarkably this world, we learn, is built on the same principles as soft technology. Grace the scientist puts it plainly: the Home Tree is a neural network connecting all trees on the planet. And if that wasn’t clear enough, we have the very explicit image of the Navi ‘jacking in’ the planetary system with their hair (Naughty as I am, I briefly wondered why would Jack and the Navi girl need to have sex the usual human way when they seemed to make love through their hair just fine).

Cornelius Agrippa: the Renaissance Magician and Faustian Hero

Wednesday, October 21st, 2009

Today I want to talk about Heinrich Cornelius Agrippa (1486-1535), the most famous (or infamous) Renaissance magician. He is the author of one of the well-known compendium of Renaissance esotericism, On the Occult Philosophy (or De Occulta Philosophia), which is still admired by people interested in magic today.

Agrippa was a German wanderer, much like his contemporary, Paracelsus. He traveled almost all his life between Germany, France and Italy, and switched professions just as easily as he switched countries. He was a theologian, a lawyer, a physician and a hired soldier. He claimed to have acquired both a law and medicine degree In the meantime, he wrote revolutionary treatises on Renaissance magic, the vanity of knowledge, the status of women in society and Virgin Mary. Most of these he refrained to publish until late in his life.

Agrippa was an unconventional scholar; for instance, in an era when women were seen as inferior and even instruments of the devil, he affirmed that they were in fact superior to men and more spiritual than them. His defense of the female sex caused quite a sensation in the period. In his De Vanitate Scientiarium, On the Vanity of all Sciences, he rejected all forms of knowledge as empty and purposeless. Even today scholars of Agrippa’s works are baffled by his universal rejection of knowledge. He was certainly an unusual iconoclast, an unique character that built and destroyed all at once.

Paracelsus, the Man and His Natural Philosophy (I)

Wednesday, September 16th, 2009

There is hardly a more controversional figure in the history of ideas than Paracelsus, by his real name Theophrastus Bombast of Hohenheim (1493-1541). He was many things to many people: a hero to some, a quack to other, a devil’s doctor, a German nationalist or a drunkard. Perhaps he was all these things, because, by comparison to most other historical figures, he was impossible to frame. In fact, Paracelsus created a world of his own and a mythology that has never ceased to fascinate since his premature death at 47.

Inevitably, any scholarly analysis of Paracelsus is bound to reduce something from his larger-than-life self. Scholars simply do not have the tools to tackle his complexity. The same is the situation of his works. He wrote a wondrous amount, and another wondrous amount was added unto him by his faithful followers. Like a religious figure, he created a veritable ‘tradition’ of writings that were attributed to him. This huge compendium is still awaiting a contemporary analysis, despite efforts in this direction (notably Kurt Goldammer).

Paracelsus was a religious figure of sorts; many people called him ‘Lutherus Medicorum’, the Luther of physicians. He didn’t like it; even though he lived during the turmoil of Luther’s Reform, he remained a faithful, if unorthodox Catholic. Instead, he proposed his own version of the world, a peculiar mixture of natural philosophy, alchemy, magic and Christianity. He was in fact the quintessential representative of the Renaissance; a man convinced of his mission of reforming people’s views of the world and of Christianity. He believed there was no inherent contradiction between the analysis of the natural world (we now call this ‘science’) and religion; in fact, Christianity was the very basis of this analysis.

The Renaissance Love Philosophy and Magic

Thursday, September 10th, 2009

It’s autumn, the leaves are yellowing and I am back. I’m happy to say that my MA dissertation in Western Esotericism is off and I will be starting my PhD in Western Esotericism. Yup, I can’t get enough of it.

In case you’re wondering (and even if you are not), my thesis was called “The Impact of Jan Baptista Van Helmont’s Theory of Love, Desire and Universal Sympathy on his ‘Christian Philosophy’”. I hope it sounds heavy enough. I will try to write an article on Van Helmont some time soon; he was a physician and an alchemist in the tradition of Paracelsus who lived at the beginning of the 17th century.

For now, I would like to write a bit on the Renaissance love philosophy and its relationship with magic. The story begins with the first Renaissance philosopher, Marsilio Ficino (end of the 15th century). Today he is remembered mainly as the translator of Plato’s treatises from Greek into Latin. History has not been very kind to him, even as he was in many ways the reason the Renaissance ever existed. Ficino re-introduced Plato, the Neoplatonists and Hermetic thinking in the discourse of his contemporary age and hence ignited a revolution of consequences.

I will not go into the depths of Ficinian philosophy now except in so far as he was the creator of a pervasive love philosophy in his era. Of course, if you asked Ficino, he would never recognize that he created it (back then originality was not well regarded). Perhaps he really didn’t. He simply tried to restore the courtly love tradition of the Middle Ages, whose chief representatives were Francesco Petrarch, Dante Alighieri and Guido Cavalcanti. He also looked farther back to Plato himself for inspiration.
