The Controversy over Brain Research

Summary

All mental processes are closely connected with the electro-chemical processes between the nerve cells in the brain, and these function in accordance with the natural laws of physics. But is free will therefore an illusion? The more precisely the neuroscientists can describe the ways in which our brain functions, the clearer it becomes that none of their measurements and models embraces the central aspect of consciousness: how we become subjectively aware of qualities such as color or smell, a reflection or an emotion. The discussion between the “scientists” and the “philosophers” in our symposium has shown that at present brain research seems not to have an empirically demonstrated theory to offer about the connection between brain and mind, between consciousness and the nervous system. In any case, chemistry and physics seem not to explain the experience of freedom of choice which is however universal and undeniable.
