Consciousness

Two interesting points:

a) An earthworm can feel pain and it has a mind. If you cut it into two, both sides now wiggle in agony. So now it has two minds? or two souls? or two consciousness? where is the original earthworm? And so a human can live with one half of a brain. If a person donates half of his brain to another person, does this donor exist in two bodies?

b)
1.Theory of Evolution states that organisms evolve with traits to help them survive better (natural selection). 2.Only a certain amount of knowledge is needed for survival.
3. There is a boundary to what we can know since our brain is part of an the evolution. There is no need to evolve such powerful brains to comprehend what we cannot comprehend. (Limit of Science)
