there is more to coherence than structuring in terms of multidimensional gestalts

"there is more to coherence than structuring in terms of multidimensional gestalts. When a concept is structured by more than one metaphor, the different metaphorical structurings usually fit together in a coherent fashion." (#60 1534)
"The difference between coherence and consistency is crucial. Each metaphor focuses on one aspect of the concept ARGUMENT: in this, each serves a single purpose. Moreover, each metaphor allows us to understand one aspect of the concept in terms of a more clearly delineated concept, e.g., JOURNEY OR CONTAINER. The reason we need two metaphors is because there is no one metaphor that will do the job—there is no one metaphor that will allow us to get a handle simultaneously on both the direction of the argument and the content of the argument. These two purposes cannot both be served at once by a single metaphor. And where the purposes won't mix, the metaphors won't mix. Thus we get instances of impermissible mixed metaphors resulting from the impossibility of a single clearly delineated metaphor that satisfies both purposes at once. For example, we can speak of the direction of the argument and of the content of the argument but not of the direction of the content of the argument nor of the content of the direction of the argument." (#60 1687)
"A shared metaphorical entailment can establish a cross-metaphorical correspondence. For example, the shared entailment AS WE MAKE AN ARGUMENT, MORE OF A SURFACE IS CREATED establishes a correspondence between the amount of ground covered in the argument (which is in the JOURNEY metaphor) and the amount of content in the argument (which is in the CONTAINER metaphor)." (#60 1711)
"Where there is an overlapping of purposes, there is an overlapping of metaphors and hence a coherence between them. Permissible mixed metaphors fall into this overlap." (#60 1717)

We understand the sentence in terms of the way these gestalts fit together

"We understand the sentence in terms of the way these gestalts fit together, both the "smaller" gestalts (GUN, FIRING, AIMING, etc.) and the "larger" gestalts (SHOOTING SOMEONE or PERFORMING A CIRCUS ACT)." (#60 2875)
