Awhile back, David Brooks wrote a New York Times column about metaphor in everyday life. (He called it “Poetry for Everyday Life.”) Here’s the link: http://www.nytimes.com/2011/04/12/opinion/12brooks.html?_r=1
My favorite line could be this one: Even the hardest of the sciences depend on a foundation of metaphors. To be aware of metaphors is to be humbled by the complexity of the world, to realize that deep in the undercurrents of thought there are thousands of lenses popping up between us and the world, and that we’re surrounded at all times by what Steven Pinker of Harvard once called “pedestrian poetry.”
