no the smart guy says it with his mouth there is no god
You must have been absent from school the day they taught about symbols and metaphors. In both Hebrew and Greek culture, the heart was thought of more as a symbol of ultimate purpose and motivation.When someone says to you, "Use your head", they are telling you to "think" or "use your brain". A little research will uncover many such uses in our everyday lives. Our language is littered with metaphors. Recent research into everyday conversation shows that we use four metaphors per minute. Why is this statistic a surprise? Because we are not aware of the vast majority of metaphors that we use. Metaphor is so fundamental to the way we think and speak that only the more obvious ones register in our awareness:I'm forever running up against a brick wall.I'm carrying the world on my shoulders.I think I'm cracking up.I see a light at the end of the tunnel.Thanks for your comment. It helps me to teach some fundamental truth about language.
