Yes. Cog Psych is exploring it right now best. But think how
   artificial the lines are? If you build an argument on "Reason
   alone" but Reason is a socio-historical construct that turns OUT
   to be a part of cognitive processes... then REASON properly - if
   one is to attempt to explain things completely... must include
   an acknowledgement of its source.

   Otherwise, it's just another layer whose base is forgotten and
   around the ice-skating rink we go, nobody looking at the water
   below. oh god i just rhymed. Sorry. hard not to wax poetic when
   it's a topic of interest
