And I think the biggest picture of all would take seriously the fact that so much of our verbiage about abstract events is based on a concrete metaphor and see human intelligence itself as consisting of a repertoire of concepts -- such as objects, space, time, causation and intention -- which are useful in a social, knowledge-intensive species, whose evolution you can well imagine, and a process of metaphorical abstraction that allows us to bleach these concepts of their original conceptual content -- space, time and force -- and apply them to new abstract domains, therefore allowing a species that evolved to deal with rocks and tools and animals, to conceptualize mathematics, physics, law and other abstract domains.
