Metaphor in a sense is how we make sense of the unknown. It is how we lasso the moon in the sky and pull it down to our level so that we might understand it or do the inverse and project it so that it is bigger than we are. Take these two metaphors for instance: The moon shines like a distant streetlight calling the neighborhood kids to come home for dinner or the her smile was a bright as the moon on a clear sky night, illuminating all the dark parts of my heart. We use it to define the unknown apply scale to things or just to be imaginative in the was we are describing things. Without the use of metaphor the world can be suddenly boring and that is not what we want do we?
The creative inquiry is the steps along which our perception of the world goes till we come out the other end with an ability to manipulate and make sense of all the stimuli the world has to offer. Once mastered we are better at communicating, pattern making, and complex intellectual functions.
Sweeter than honey!
