Why do you think those are good analogies? None of those things undergo a process of growth and development.Do you need a volt meter, a prod, it’s obvious to me as obvious as there is an engineer, architect, planning when I see an automobile, building, bridge. Or a computer, according to your thinking it doesn’t need software, just a hunk of metal, plug it in and it works.
That’s why it’s comical that you can believe human beings are reduced to just physical impulses by chemical reactions and that’s it.
Maybe instead of thinking it comical, you should look into why people who actually study this stuff think it is true.
We have been studying the brain for the last 150 years, the neurons for about 100 years, neurotransmitters for about 50 years, and have only mapped out important pathways for personality in the last decade or so. ANYTHING written about this subject that is more than 20 years old is badly out of date.
