It’s been surprising how positive the metaphors have been, even from those people for whom sustainability is not a strong idea, or from those who acknowledge its ambiguities.
It's also been surprising to see how people have found something, maybe not the grand conceptual metaphor, but something in their lives that relates to their view of sustainability. This is as important as the encapsulating metaphor, like the 'iron curtain' or the 'glass ceiling'. The metaphors have not been about a concept imposed from the outside, but about a relation between the idea and something from one's life that makes sense.
We'll be presenting more metaphors in the next two weeks.
