“Science shows that more than half our body is made of ‘non-human’ cells.  We are hosts for billions of other microscopic life forms.  We do not know what these life forms look or feel like, yet they dictate how our body functions.  Likewise, we do not know what our thoughts are or where they come from.  Our thoughts are perhaps not ‘our own’ either.  As with the computer, perhaps evolution means shrinking in size.  Thus, our thoughts may be another, more advanced life form, living in our brains.”
