Apologies in advance, as I know this has been discussed before. I believe that, ultimately, the human body is comprised of nothing more than inanimate matter. Yes it's complex, but every organ, in fact every cell in the body, is ultimately comprised of atoms and associated sub-atomic particles. Break the human body down that far, and eventually its pieces are indistinguishable from pieces of rock, water, or interstellar dust. If we are ultimately built from inanimate matter, how could we ever have free will? Our bodies, and very likely our thoughts, are the results of interactions between lifeless particles. How is there free will? Is free will a myth? To tell you the truth, I'd feel better about my life if I knew that free will was a myth. Sounds sad, but that is how I feel.
