First of all, this is a great post!

"The map is not the territory" - each one of us has a different reality because the information coming to us from our senses processed differently for every person. The implications are that there is no absolute reality :)
Which also means that our brain giving the meaning to stuff... Which also means (Ironic) that there's no absolute meaning to life :D
