In the first of a series of member profiles, retired art teacher Norma Smith talks to Barry Daniel about her life, why she became a member of the society, the middle way, the importance of art in her life, agnosticism, and the power of metaphor. With regard to the latter, she was especially enthusiastic about the work of George Lakoff. Please see link to a youtube talk he gave on metaphors as embodied meaning below.
George Lakoff: Frameworks, Empathy and sustainability
There is also a slide show version of the podcast available on Youtube.
May I recommend you look at an article on Google:-

I hope to write more on the subject, when I have done more research.
