 Chomsky’s notion ‘E-language’ is supposed to suggest by its initial ‘E’ both ‘extensional’ (concerned with which sentences happen to satisfy a definition of a language rather than with what the definition says) and ‘external’ (external to the mind, that is, non-mental). The dismissal of E-language as an object of study is aimed at critics of Essentialism—many but not all of those critics falling within our categories of Externalists and Emergentists.
