Metaphors also involve relations among relations, but are partly based on common properties of the related stimuli or events1. For example, a therapist might tell a client this metaphor: “Struggling with anxiety is like struggling in quicksand.” This metaphor is a context that specifies a relation of sameness or equivalence between these two relations. But this relation is not completely arbitrary. The two events share some common properties that make the metaphor useful.
Struggling with anxiety is like struggling in quicksand.
