He has to establish what he affirms, which is obviously impossible. We see that it is safe to start with such solid negative premises, translate them into positive language, and build a null-A system. [non-aristotelian]

The only usefulness of a map or a language depends on the similarity of structure between the empirical world and the map-languages.
