 The relevance of all this to the philosophy of linguistics is that the theorem just sketched has been interpreted by many linguists, psycholinguists, and philosophers as showing that humans could not learn languages by inductive inference based on examples of language use, because all of the well-known families of languages defined by different types of generative grammar have the crucial property of allowing grammars for every finite language and for at least some infinite supersets of them. But Gold’s paper has often been over-interpreted. A few examples of the resultant mistakes follow.
