Reality as if is doubled in relation to language. Language and reality are referred to each other. Their relation can be discussed as a set of mappings between them. Depending on those mappings, reality and language can be considered either as two identical copies (or “monozygotic twins”) or as two similes (or “fraternal twins”). Representation is the former case (“copies”), and metaphor is the latter one (“similes”): So, representation and metaphor are correspondingly “image and simile” between reality and language. The metaphor can be anyway defined to a set of one-to-one representations of the only similar external twin into a set of internal “twins”, each of which is a different interpretation of the external “twin” so that a different metaphor is generated in each case. The representation seems to be vague, defocussed, after which the image is bifurcate and necessary described by some metaphors within the language..
Consequently reality is in an indefinite, bifurcate position to language according to the choice formalized in the axiom of choice. If that choice is granted, the language generates an exact image of reality in itself; if not, only some simile can exist expressible within it only by metaphors.
Language and reality can converge, e.g. as ‘ontology’: Ontology utilizing metaphors can describe being as an inseparable unity of language and reality within language abandoning representations and the conception of truth as the adequacy of language to reality. Furthermore, those metaphors should coincide with reality (and with physical reality in particular) in virtue of the ontological viewpoint.
