Metaphor, Simile, and the Exaggeration of Likeness

This article reveals an overlooked way of interpreting sentences like “The Internet is crack [cocaine]” or “Libraries are supermarkets.” Many existing theories of metaphor could apply here. However, they can instead be interpreted in a likeness-exaggerating way, under which “Libraries are supermarkets” is simply an exaggerated way of saying that libraries are like supermarkets to a very high degree. This interpretation option follows from simple, general considerations about exaggeration and likeness scales. In this way it is preferable to the abbreviated-simile view of metaphor, and in any case it can be added to any existing metaphor account. It has broad significance for the theory of metaphor and simile, but also provides a new, straightforward explanation of the special, likeness-strengthening effect in utterances such as “Libraries aren’t merely like supermarkets, they are supermarkets.” This effect exists despite evidence that X-is-Y metaphors do not generally convey more likeness than corresponding similes.
