Natural Phonology (henceforth NP), founded by Stampe (1969, cf. 1980), and not to be confused with Natural Generative Phonology (henceforth NGP, as in Vennemann 1972 and Hooper 1976) and other ‘natural’ and ‘concrete’ trends in process phonologies (as in Brucket al.1974, cf. §3·3), has been well expounded in Donegan & Stampe (1979b) and, in terms of its application to language acquisition, in Edwards & Shriberg (1983). Important differences from Generative Phonology (henceforth GP) have been enumerated by Wojcik (1981). It is not my intention to repeat these expositions, but rather to answer those criticisms that have so far been answered only partially, such as the objections to NP discussed in Anderson (1981), Dinnsen (1978), Dinnsen & Eckmann (1977, 1978), Drachman (1978, 1981), Dressler (1974a), Hellberg (1980), Kodzasov & Krivnova (1981: 145ff), Lass (1980, 1981).
