|L||What is known — Knowledge (cf. epistemology) — are expressions (models) in a language.|
|I||What there is — Being (cf. ontology) — is the (ultimately ineffable material) substrate (reality) of nature, of which everything is made.|
|S||A linguistic compiler maps language to language (simulation) and is substrate-independent.|
|A||A synthetic compiler (or substrative compiler) maps language to a substrate-dependent object (assembly) — e.g., a biocompiler.|
|N||The language (model) is not the substrate (reality) — but languages can be compared by precision and utility. A simulation is not an assembly.|
