Throughout this session I had ‘Where is my Mind?’ by the Pixies in my head as the question we were tackling was: Where is the mind located?
A.) In our brain? Our Body? Neither?
B.) When/Where do we end?
We studied this painting by Johannes Vermeer titled ‘Woman in Blue Reading a Letter’ 1662/63.
Robert quipped ‘It’s interesting how painting – just coloured pigment on a surface – makes one imagine a person, a life…’ and explained how, although this ‘woman’ is not actually there, there is still a life behind (or within) the painting. We as observers can’t tell what the woman is thinking or feeling, and further yet, where the feeling is; in the paint or in our minds? I said ‘perhaps it’s in the artist’s mind, as they are the only person who could have known for sure what the letter was about, and what the woman would have been feeling’, but Robert quickly came back to the original concept: ‘But where is the thought?’.
Annoying, right?! I come out of these lectures wanting to float around and say ‘what is life? What is life?’ over and over. But nonetheless I keep coming back, because it’s interesting stuff.
Theory time!
Internalism: The theory that the mind is in the brain.
People who went/go by this theory are (from left to right) William James (b 1842), Hermann Von Helmholtz (b. 1821) and Chris Frith (b. 1942).
Helmholtz believed that experience is subjective, that our sight is made by our brains, the things we see are not actually in the real world.
Backing that theory up is Chris Frith who believes, for example, we are not seeing a tree for what it is, we are seeing a picture of it in our head.
This is the general belief within science today, that thoughts are generated by the brain, an organ inside our head.
This theory has basically been proved by DECODING NEURAL SIGNALS: Scanning someone’s brain whilst they are having a thought. With the use of a machine invented by Jack Gallant – a researcher at the University of California, Berkeley – a person’s thoughts can actually be reconstructed and projected on a screen as an image. This person will watch a movie, and their brain patterns (being cleverly scanned and recorded) will basically match the movie. The image will be fuzzy and somewhat off colour but the basic shapes and movements that are going on in the original movie will be reflected in the person’s brain scans. This kind of means that viewing and imagining are the same thing.
Whoah.
Below is an example of the outcome of this experiment.
Robert said: ‘You will never find a specific location of the brain for consciousness, as it is all conscious at the same time‘. He explained that there are ‘Neural Correlates‘ but this is not evidence as to why we think.
Externalism: The theory that the mind is not in the brain.
Robert introduced us to a phenomena called ‘Change Blindness‘ which is a flashing image in which something changes and generally goes unnoticed. This is essentially how magicians work.
Humans can only focus so much; the world is what we see/perceive/interact with, and this becomes our reality. If something goes unnoticed by us, it pretty much doesn’t have an existence as far as we’re concerned.
A way of summing up the Externalist view is: ‘We are not our brains, it’s the outside world which we rely on.’
(Clark, Philosopher, 2008) Believes by using technology we are spreading our minds out into the physical world. E.g. if one was to know a friend’s phone number off by heart and call them, or not know their number off by heart but instead find it saved on one’s phone and then call them, the outcome would be the same. I suppose this is the Quantum Physics way of saying technology is latching onto our brains…? Eating our brains?… Zombies? Basically, technology is giving us the tools we need to bridge the gap between our non-material minds and the material world.
Leonardo DaVinci believed that when it comes to Externalism and Internalism, we only have to choose between them if we put boundaries on them both. DaVinci being the ‘No Lines’ man disliked the idea of outlining objects/figures when drawing them, as lines don’t actually exist. When it comes to drawing there are no real lines, just dark shapes against light shapes. As humans we can never be sure where we end and where objects begin, it is only because we place boundaries on everything in life that we have an idea of what reality is.
I grabbed another quote from Robert saying: ‘Skin is a permeable membrane that does not separate us but connect us to the world’. Which basically backs up what DaVinci was going on about. The idea of the part boundaries play in our perception of reality is really interesting.
