Do we really need a brain? Fundamaterialists say "yes" because to them the brain magically creates consciousness through pixie dust or something. Science says "perhaps not."
There is the brain scan (or better yet, lack of brain scan) of a man in France who is a fully normal and functional unit in society. Here is a man with almost no brain and yet he is just like anyone else. The Fundamaterialists are scratching their heads, which are far up their asses, trying to ignore people like this because they present possible evidence that consciousness is independent of physical matter and isn't generated by the brain at all. Thanks to Michael Prescott for the links.
