Metaphor

"The essence of the metaphorical process is that it enables us to understand one thing better by likening it to something it is not"
(Gary Madison in his Hermeneutics of post modernity 75)

Is this not but a great food for the artistic thinking !?!
What does it mean for the artist to work with and through metaphors ... ?

how to say what we want to say and though the almost metaphorical movement that comes out of our bodies?
