Evidence and reason Alan, that is what we resonate to. We don't get that from you; we get assertion, tortured logic, contadictory reasoning, mangled vocabulary, all topped off with a nice dollop of general slipperiness.
But is it reasonable for you to assume that every thought that comes into your head is the unavoidable result of the forces of nature acting on the material within your brain?
By and large, yes, I would say. One thought triggers another thought, there is a chain reaction, cause and effect. Sometimes thoughts seem to just pop into our head; I think in those cases the precursor event is too subtle or below the level of our awareness for us to be aware of the cause of the effect but that doesn't mean there isn't one. You might recall I have posted up thought experiments in the past that help us to understand that our thoughts have origins that might not be obviously discernible, and the reason being that they originate in the depths of subconsciousness.
Questions for you:
What drives your thoughts?
What perceives your thoughts?
What is a thought?
Not easy to answer I agree, but in part that is due to poor definition of what is meant by 'thought'.
What drives ? I would hazard volition - desire, fear, hope etc.
What perceives my thoughts ? I think my thoughts. 'Perception' would imply there is something other than me involved, some sort of secondary observer. I see no mileage in that.
What is a thought ? how long have you got ? Problem is, there are a variety of neurological phenomena that we might casually call 'thoughts'. It might be a moment of realisation, it might be an idea, it might be a line of reasoning silently verbalised in your head as you do when rehearsing an argument in advance.
I fully accept that it is hard to reconcile ourselves to the fact that the cerebral activity we might see using instrumentation such as an fMRI scanner is the same thing as thoughts, feelings, sensations. But that is what the evidence suggests is the case and I think it better to try to cross that difficult conceptual bridge rather than fall back on make believe which your position amounts to, given there is no evidence at all for souls and so forth. Our scientific understanding of these things is proceeeding apace, the Samsung Galaxy Note 10.1 for instance uses thought control, and we could only build such technology because thoughts are ultimately physiological things which can be measured and weighed like anything else in the material world.
