This billboard came to my attention while listening to The Gardens of Democracy on KUOW. The speakers are Eric Liu and Nick Hanauer, speaking about thier book: The Gardens of Democracy: A New American Story of Citizenship, the Economy, and the Role of Government
In the recorded talk, the authors give a very appealing idea of a different metaphor to use as a basis for conceptualizing how we view ourselves in relation to needs of the environment and society around us, and what our obligations for action might be. Essentially they say that if we view the image of a garden and the understanding that a garden needs tending, this will be a much more useful metaphor than the more common one they call the mechanistic view, that the world and our society are like a machine that just needs getting started and then spins on dependent only on its internal perfection.
The metaphors we use shape the way we think about solutions. I like their garden metaphor.
