All sciences have progressed exclusively because they have succeeded in establishing their own [non-A] languages. For instance, a science of thermodynamics could not have been built on the terms of ‘cold’ and ‘warm’. Another language, one of relations and structure, was needed; and, once this was produced, a science was born and progress secured. Could modern mathematics be built on the Roman notation for numbers—I, II, III, IV, V.? No, it could not.
