No objective world

Metaphors are much more powerful instruments in the eyes of Lakoff and Johnson.

Metaphors have entailments that organize our experience, uniquely express that experience, and create necessary realities. Lakoff and Johnson attacked the two commonly accepted theories of metaphor. Previous theories derive, they believe, from a naive realism that there is an objective world, independent of ourselves, to which words apply with fixed meanings. But the answer is not to swing to the opposite and embrace a wholly subjectivists view that the personal, interior world is the only reality. Metaphors, for Lakoff and Johnson, are primarily matters of thought and action, only derivatively of language. Metaphors are culturally-based, and define what those with certain assumptions and presuppositions find real. The "isolated similarities" are indeed those created by metaphor, which simply create a partial understanding of one kind of experience in terms of another kind of experience.

They are grounded in correlations within our experience.
