Templates and narratives for change

At the end of a conversation with David Runciman about powerful women on the Talking Politics podcast (reposted on the LRB podcast; their chat starts around 18:00), Mary Beard had this to say:

The idea that women have a model for doing [changing the structures within which women can think of themselves as ambitious, as powerful, as clever, as articulate, and able to make that kind of difference in the world] -- and I don't mean a kind of role model, but I just mean a kind of cultural template for doing that -- until we can provide a narrative and a template, then I think we've got a problem.

This resonates with what I try (and fail) to do in policy innovation. It's not sufficient to have a new idea (= template). You also need to have a story (= narrative) that explains why anyone should care, and why it makes sense.
