  Austin (1950) rejects the isomorphism approach on the grounds that it projects the structure of our language onto the world. On his version of the correspondence theory (a more elaborated variant of (4) applied to statements), a statement as a whole is correlated to a state of affairs by arbitrary linguistic conventions without mirroring the inner structure of its correlate (cf. also Vision 2004). This approach appears vulnerable to the objection that it avoids funny facts at the price of neglecting systematicity. Language does not provide separate linguistic conventions for each statement: that would require too vast a number of conventions. Rather, it seems that the truth-values of statements are systematically determined, via a relatively small set of conventions, by the semantic values (relations to reality) of their simpler constituents. Recognition of this systematicity is built right into the isomorphism approach.
