Question

why are we troubled by the realization that our brain can create things which we may not be able to control ​

Answer 1

You compare revelations in neuroscience with the discoveries that the Earth goes around the sun and that the heart is a pump. What do you think these ideas have in common?

They challenge a whole framework of assumptions about the way things are. For Christians, it was very important that the Earth was at the centre of the universe. Similarly, many people believed that the heart was somehow what made us human. And it turned out it was just a pump made of meat.
