The IDEAS ARE FOOD metaphor fits our experience partly because of this metaphor-induced similarity. The IDEAS ARE FOOD metaphor is therefore partly grounded via the MIND IS A CONTAINER and CONDUIT metaphors. As a consequence of the IDEAS ARE FOOD metaphor, we get new (metaphorically) similarities between IDEAS and FOOD: both can be swallowed, digested, and devoured, and both can nourish you. These food concepts give us a way of understanding psychological processes that we have no direct and well- defined way of conceptualizing.引自 第二十二章 相似性的产生 136
