“If our bodies were different, though, our metaphors would be different, as Olaf Stapledon showed in Star Maker. Crabs walk sideways, for instance. If crabs could talk, they would undoubtedly describe progress in difficult negotiations as sidling toward agreement and express the hope for a better future by saying their best days are still beside them.

Our bodies prime our metaphors, and our metaphors prime how we think and act.”
