 “Margaret Thatcher cannot, for example, move huge quantities of dirt in an efficient manner” (87). Nor is she routinely prepared to get dirty in any literal sense. Listeners can be counted on to know as much and notice as much. So confronted with (2), they cast about for a possible adjustment to the previously prevailing canon of similarity that brings the content of (2) into line with conversational principles and is manifestly smaller, manifestly more natural, manifestly easier to make, than any other adjustment that would do the trick. This adjustment relaxes the standards of how like a bulldozer a thing needs to be in order to be just plain like a bulldozer, like a bulldozer without qualification. And it bestows fresh salience on relatively abstract features of bulldozers, features a powerful person might credibly share: an ability to take on large tasks, an ability to wear down large obstacles a little at a time, a certain gracelessness in moment-to-moment operation, etc.
