Dualism: the theory that the mind is a seperate entity to the physical body.
- The close relationship between the brain and the mind. Have a beer; alcohol travels through the system and begins to interfere with the transfer of electrical signals in the brain. Sure, after one beer the effects aren't too noticable, but from about five beers onwards there is a noticable change in the body, and, more importantly, the mind. Motor skills become hampered, the ability for complex thinking and risk analysis is severely reduced, and many more. In this case a direct correlation between changing circumstances in the physical brain and the conscious mind can be seen.
A further example is brain damage. Our lecturer made the example of a railroad worker who had a metal spike driven clean through the front half of his head in an explosion and survived. At first it seemed like he was no different, until a few uncertainties began to appear. He was no longer able to hold down his job and drifted from one to the other, losing his family in the process. It became clear that the man had lost the ability to make long term plans, or even acknowledge anything further than the direct short-term future. The correlation between parts of the brain and different aspects of the mind suggests that the mind is directly tied to the body. Damage or changes to the brain = damage or changes to the mind.
- If the mind is a non-physical entity, then how does it interact with the body? Touching an object sends an electrical signal along the nerve fibre and up the spine and to the brain - a completely physical process. How, if the mind is non-physical, would it recieve this signal. How would it then send it?
There's a few more very powerful criticisms of the dualist theory, but I can't remember them off the top of my head. I used to think that the mind was seperate from the body, but now I've got a much different theory which I've been meaning to post but I haven't got around to. I guess I'm still contemplating it a bit.
A very good point. It depends on what kind of consciousness is referred to, though. Yes, it was an act of mind - they were responding to the stimuli of rain, which can be seen as the 'access to information' part of consciousness. They were not 'self-aware' of the act though (I think it's safe to say). They were not thinking in terms of an ego, "oh, I should stop chirping now" and I doubt they were aware of their decision though. Consciousness is dependent on intelligence. The higher up the order of intelligence in the animal kingdom you go, the more self-awareness you get. Cimpanzees, for example, are able to recognise themselves in the mirror.
Hmm... well basically my idea on consciousness is that it is a phenonemon that enables the brain and body to form a model of its environment and therefore interact with it in complex ways. I was going to explain it some more but I've kinda run out of steam haha. I'll try and explain it some more later.

Actually, when I get trashed, there still is a conscience - there still are ethics, but I just choose to completely ignore them.
I was almost alcohol poisoned (if I didn't puke over a gallon of w/e I ate and drank that night I would have probably landed in the hospital). But that whole night, I was doing stupid crap, and the whole time... there was always this voice for a split second "you shouldn't do this, you are drunk right now", and then me going "nah, I don't care it's fun". And I also have brief memories of my head being a garbage can with the voice in the back of my head going "never again... never again...", and it was right. I still get drunk once in a while, but I keep it at a controllable level now.
And the guy with spike going through his head - it's also possible that his mind just simply lost the ability to use that part of his brain. You can argue that "he" is still there, just as "I", my super-ego was "still there" the night I almost went to far.
