The 'standard theory' of Chomsky and Halle has dominated phonology in
recent years. It has been subject to modification and to criticism but
not of a really fundamental kind. Dr Foley does here offer a fundamental
criticism and a genuine theoretical alternative. He argues that
transformational phonology, like previous phonological systems, is
primarily concerned with the description of superficial sound changes
and not with the underlying processes and rules; it is perhaps more
accurately termed 'transformational phonetics' for that reason. A
theoretical phonology, he argues, will consist of a system of
phonological elements, a set of universal rules relating these elements
and a set of principles governing the operation of the phonological
rules. The basic phonological elements are therefore defined not by
physical acoustic or articulatory parameters, but by their participation
in rules. Such a theory is developed here and illustrated in the
analysis of various phonological problems. It is shown that many
apparently diverse phenomena can thus be connected and explained and so
be subject to genuinely scientific enquiry.
