On the Need for a Phonological Base

Pre-Chomskyan linguistics recognized that the phonological systems of natural languages tend to form symmetrical patterns; this insight could be incorporated into generative phonology via a phonological base component, but is not adequately expressed by MS rules. A phonological base would also solve some difficulties in the theory of systematic phonetics. Current lack of interest in phonological patterning has resulted from the increased attention paid to morphophonemics; but the deep vs. surface distinction in phonology can be demonstrated on the basis of patterning even in languages lacking morpho-phonemic alternation. That distinction, it is argued, may be of only historical validity, whether or not alternations occur in the language.
