Yes, that’s right, it says it all in the title. Not that I don’t intend to do my University work, it’s just that before I can get my mind in gear to try and understand the intricacies of computational mind theory, I need to prime my own mind somehow. So a blog it is.
The course I am studying is the level 3 philosophy offered by the Open University. I completed level 2 last (academic) year and surprised myself by coming out of it with a distinction. So the obvious next step, is level 3. The not-so-obvious ‘other’ step, is social science, which I am also studying, mostly because I needed one more course to complete my degree, and there was nothing else left I was really interested in. (so far the social science is quite interesting, if light)
The social science course is ‘level 1’ (are you following this?) – meaning it is roughly equivalent to first year study – so full of fluff, hand-holding, broad but with not much detail. Unfortunately for me, when I started studying with the OU (about 3 years ago) – I hadn’t really planned to get a degree, I signed up purely for the creative writing courses, which I completed, and then though “why not?”
The only small problem is that thanks to my impulsive approach to education, every-time I revert back a ‘level’ I have to put up with the introductory elements that presume you have just started learning – as the assumption is you will study a couple of level 1 courses, followed by level 2, and then onto the third level. I on the other hand have gone:
Year 1: Creative writing level 2
Year 2: Creative writing level 3
Year 3: Western Philosophy level 2 / History of the arts level 1
Year 4: Philosophy of the mind Level 3 / Social Science level 1
So it’s a mixed bag of difficulty and subjects, but I’m getting through them (I’m on year 4 now, my final year before receiving a BA Honours, all being well)
But why am I telling you all this? Well, because I tried yesterday to get ahead on my philosophy and absorb three chapters of theory of mind in one go, only to find my own mind melting somewhat when I arrived upon computational theory. As far as I can tell from what I gleamed before I shut down, is that CTM (computational theory of mind) believes our thoughts to be a semantic syntax, used, like a computer would use a programme, to respond to and trigger physical and mental processes. However – it’s not as easy as all that.
So far, the philosophers I have covered in the first section on ‘the mind’, have said that we (our minds) are simply our outward behaviours, or we are the inner things that cause our behaviours , or that we are disembodied immaterial substance that communicates with, but is not part of, the material body (which I rather like but the upshot of Descartes rigid doctrine is that animals don’t feel pain – which is rubbish). But as with all Philosophy, none of them have a very clear advantage over the others, and some (CTM) are overly complicated to arrive at only a slightly different conclusion, that still has all the pitfalls of most other theories.
For example, to put it simply, if our thoughts are just the programming language of our bodies and our other thoughts, who is doing the programming? And why don’t advanced computers have any signs of free-will? Why the need for a biological component at all? Why don’t self-aware calculators spring from the dust? (I like that last one, I might use it for a short story).
This is hardly a comprehensive critique of this theories – if my essay looked like this I would be in for a hard time – but these questions are begged, and rarely, if ever answered.
A warning for you who may fall into these conversations with someone who thinks they ‘get it’ or know the answer – they don’t. This debate has raged for thousands of years, and will rage for thousands more. Advances in neuroscience have brought a new dimension to understanding what we are in our ‘eds, but not answered anything to do with the simplest thought ‘I am’ – which is what Descartes was getting at, even if he felt the need to place this in a rigid doctrine to try and encompass his particular faith.
My favourite dichotomy, put forward by David Hume, is that the self is a ‘fiction’ cause by the rapid mental processes, merely creating the illusion of a greater whole. It’s very easy to place this in an constructed argument as follows:
A. An illusion requires an observer.
B. The self is an illusion.
Therefore: The self requires an observer.
In the semantic logic of philosophy, if statement A and B are true, and the conclusion encapsulates both statements, the proposition must be true. This is a sound and valid argument, and one that defeats most theories of mind that try to ‘cut out’ the observer. Simply replace statement A with ‘A programme requires a programmer’, B with ‘The self is a programme’ and we have a similar conclusion, with ‘observer’ replaced by ‘programmer’, which arguably, is the same thing.
There is a lot of semantic and even syntactic argument in philosophy, as if we can unlock truth with combinations of words, or derail theories with scrutiny of the language used. This is necessary, as these concepts have a certain precision that needs to be communicated, so sloppy language can dilute conclusions. This is exactly what happened with Hume when he used the word fiction. A fiction can’t exist in a vacuum. (cue jokes about hoovering up Jane Eyre…)
Anyway, as I said, I just needed to get my mind going a bit, and this is a bit of a ramble. Maybe you found it interesting, maybe you didn’t – but I’m off now to try and wrap my head around the details of CTM, and as interesting as it will be, I never expect it will answer these questions, I feel it is one of those causal riddles that lie at the heart of everything and we may never know – but we must try, as it keeps us linked to ourselves as energetic and intelligent beings, seemingly blessed with the rationality to have these debates out of all living things, a task we must at least acknowledge.
