Philosophically, there is a difference between the brain activity that is associated with thought and the sensations we experience. As Greylorn has pointed out, it has long been understood that electricity plays a major role in brain states that induce thought processes, but the electro-chemical brain states that we can examine with scientific instruments are not the consciousness that we can only access by talking about it. I can tell you all about what I am thinking, but I cannot tell you what the actual physical processes in my head are. I think you need to be clear which you are talking about at any given moment.

My point is only that thought exists as part of the physical world, and as such it has properties.
I think that is almost certainly true. The thing is, people are doing research on what physical processes are involved with what experience. But while philosophy of mind is not my strong suit, I know next to nothing about neurobiology and I couldn't tell you what the latest research has found. What I do know is that the long haired Australian hippy philosopher of mind David Chalmers has, as I have mentioned already, distinguished between brain activity and our conscious sensations, calling the latter 'the hard problem'; as if working out brain activity wasn't hard enough. The brain activity certainly has properties, as you suggest, but it is not clear that altering those properties will have a reliable effect on anything but gross mental states.
Felasco wrote:Whatever those properties might be, they would have an influence on anything made of thought.
They would certainly have an influence on the brain states. Whether they would therefore have a consistent influence on mental states, what one perceives or thinks, is a more complicated issue. How and what one thinks is almost certainly a product not only of the raw electro-chemical activity, but the neural connections ones brain has made; roughly speaking, what state will lead to what connections and hence what later state.

All philosophies are made of thought, and thus all philosophies inherent the properties of thought, just as all creatures made mostly of water inherent the properties of water, even though they may come in many different sizes, forms and shapes etc.
What do you think we can learn about animals that we can learn by studying the properties of water?
Felasco wrote:Point being, to the degree we understand the properties of thought itself, we learn something about all philosophies.
This is a different way to study philosophy. We set aside a debate between this idea and that idea, and study what all ideas have in common. A shift of focus from the content of thought, to the nature of thought.
This is a division of philosophy of mind, Baba Bozo, people do examine thought in that way. The study of the electro-chemical activity inside brains is part of neuroscience; there is a lot of it going on.
Felasco wrote:people think; it doesn't follow that there is something independent of their thinking.
There is something independent of the
content of a particular thought. As example, let's pretend that we'd established that thought is green in color, that is one of thought's properties.
The color of thought would be independent of my opinion of Plato's philosophy. Our opinions on Plato might vary widely, but all our opinions would be green, as they are all made of thought.
I don't follow. What more is there to say about green other than it is green?
