Because they are made of dense concentrations of neurons.
I'm honestly not sure what you're trying to ask. I've tried to answer the best I can, even stating, "My brain has the capacity to determine if things are true by testing the evidence that it receives and seeing if that evidence is self-consistent and also consistent with other true things it has determined." You immediately dismissed that by claiming that that was how my brain did it, not me, despite the fact that I have made it very clear that my position is that I am my brain.
If I draw a point on a piece of paper, and then draw a series of secondary points that are all an equal distance from the first point, but off in different directions, those secondary points will form the outline of a circle. But how can they be circular? What is it that gives those points circularity? You might say that it is because they are all the same distance from a single point, but that doesn't explain how the secondary points obtain circularity.
That's what it's like trying to discuss this with you.
The mental events are the result of electrochemical signals acting across brain matter.
So you think that a complex system that has trillions of connections and is constantly changing is going to be predictable?
Have you never heard of chaos theory? We can't even predict the flow of water coming out of a tap, how do you expect to predict this? The three-body problem is simple compared to the brain, and we can't predict that either. Your optimism is naive.
Oh, how condescending. You're going to answer my question as a reward to me for having a go. Yay! I get a participation trophy!
And your participation trophy is a complete non answer. You have nothing. You can't support your position, and you have several times backflipped on your position. You've got nothing of value to discuss.
Q1. I don't follow your answer. How does being made made of dense concentrations of neurons make something capable of truth acquisition?
Q2. Something is circular when it uses it's conclusion as part of it's premise. Using a brain process as a means of testing your brain process is circular. I'm hoping to hear a reasonable answer, not any answer.
Q3.I don't get your point here. If you don't know how matter has intentionality just say so.
S1. If the The mental events are the result of electrochemical signals acting across brain matter then the mental events are not the brain matter or the electrochemical signals. So what are they under materialism/physicalism?
S2. There is small range of indetermination sure, but it is also largely predictable. We know where the water is going when it comes out of the tap, and we know where it isn't going and thats the majority of the room. There is only a small range of uncertainty. To go from being determined to purely random doesn't solve your problem of being useful in regards to the truth. All you have done is change the statement from "you haven't thought about X", to "you haven't thought about X", or your "statements are purely random". If you want to appeal to chaos theory than you have just made the case that every statement you make is more likely false than true.
I wasn't trying to be condescending. I am trying to be fair toward your questions because you will not be able to provide an answer toward my questions because they are hard problems. I was also trying to say that I recognize that you are trying to answer these questions.
I can certainly say to you that you have nothing. You can't support your position, and you have several times backflipped on your position. You've got nothing of value to discuss. I haven't backflipped you just haven't been reading my statements well. Remember 503? The difference between our two theories is that one is material and one is immaterial. The former should be described by physics and chemistry, the later should not. So expecting me to be able to describe the soul with physics and chemistry is misguided. A soul is something that can only be apprehended, and it appears to be a metaphysical necessity given that physicalism and materialism fail to account for what is there, and fail to provide the means to account for the acquisition of truth. It turns out that there is a metaphysical thing in this world whose properties are
only changed by 2 things in the entire world! You know what that is? Other minds, and meaning. Minds are changed by love, Minds are changed by compassion, and they are changed by hatred, frustration, and anger. Chemicals are produced for these things but it is the meaning that changes the heart of the mind. There is no place for a reductionist account of consciousness in this world.
