You can't see oxygen either but do you believe in that? YES!!! Exactly, that was my point in the first place. Just because you cant see something doesnt mean that it doesnt exist. Thoughts are caused by the complex movements and interactions of a range of very, very small chemicals that aren't significantly larger that O2 molecules. Never mind the limits of human vision and the practicalities of being able to see inside the head of a living person, the laws of physics would prohibit us from seeing/recognising them in any meaningful way. We can however stick electrodes in peoples brains and evoke or invoke a wide range of thoughts and emotions. We can give drugs to people, with known mechanisms of action, which can influence their thoughts and emotions. Brain injury either traumatic or otherwise can result in people being unable to have or process certain kinds of thoughts, the list goes on and on. Exactly, but i still havent see how a human thought looks like. Sure, we cant track them, acsess them and study them, but we can never actually see how they look like. Like it or not this is evidence of the physical nature of thought.No, its the evidence of an exsitance of a human thought and that we can change them. I never denied that they existed nor did i say we cant operate on them. I just said there is no physical evidence of them. Better evidence is dependent one or two factors; significantly better technology than we currently have or a major shift in ethics which renders experimentation on live human subjects once again acceptable. |
