Kisseberth (1970) introduces the notion of conspiracies, cases in which a series of phonological rules in a single language “conspire” to create similar output configurations. Supposedly, Haj Ross chose the term “conspiracy”, and it is perhaps not an accident that the term he chose immediately reminds one of conspiracy theory, which has a strong negative connotation implying that the existence of the conspiracy cannot be proven. Kisseberth’s discovery of conspiracies motivated the rise of Optimality Theory (OT) two decades later—Prince & Smolensky (1993:1) refer to conspiracies as a “conceptual crisis” at the heart of phonological theory, and Zuraw (2003) explicitly links Kisseberth’s data to OT—but curiously, it seemingly had little effect on contemporary phonological theorizing. (A positivist might say that the theoretical technology needed to encode conspiratorial thinking simply did not exist at the time; a cynic might say that contemporaries did not take Kisseberth’s conspiratorial thinking seriously until it became easy to do so.) I discern two major objections to the logic of conspiracies: the evolutionary argument and the prosodic argument, which I’ll briefly review.
The evolutionary argument
What I am calling the evolutionary argument was first made by Kiparsky (1973:75f.) and is presented as an argument against OT by Hale & Reiss (2008:14). Roughly, if a series of rules lead to the same set of output configurations, they must be surface true, or they would not contribute to the putative conspiracy. Since surface-true rules are assumed to be easy to learn, especially relative to opaque rules are assumed to be difficult to learn, and since failure to learn rules would contribute to language change, grammars will naturally accumulate functionally related surface-true rules. I think we should question the assumption (au courant in 1973) that opacity is the end-all of what makes a rule difficult to acquire, but otherwise I find this basic logic sound.
The prosodic argument
At the time Kisseberth was writing, standard phonological theory included few of the prosodic primitives; even the notion of syllable was considered dubious. Subsequent revisions of the theory have introduced rich hierarchies of prosodic primitives. In particular, a subsequent generation of phonologists hypothesized that speakers “build” or “parse” sequences of segments into onsets and rimes, syllables, and feet, with repairs like stray erasure, i.e., deletion, of unsyllabified segmental or epenthesis used to resolve conflicts (McCarthy 1979, Steriade 1982, Itô 1986). It seems to me that this approach accounts for most of the facts of Yowlumne (formerly Yawelmani) reviewed by Kisseberth in his study:
- there are no word-initial CC clusters
- there are no word-final CC clusters
- derived CCCs are resolved either by deletion or i-epenthesis
- there are no CCC clusters in underlying form
The relevant observation that links all these facts is simply that Yowlumne does not permit branching onsets or codas, but more specifically, Yowlumne’s syllable-parsing algorithm does not build branching onsets or codas. This immediately accounts for facts #1-2. Assuming the logic of the McCarthy and contemporaries, #3 is also unsurprising: these clusters simply cannot be realized faithfully; the fact that there are multiple resolutions for the *CCC pathology is besides the point. And finally, adopting the logic that Prince & Smolensky (1993:54) were later to call Stampean occultation, the absence of underlying CCC clusters follows from the inability of them to surface, since the generalizations in question are all surface-true. (Here, we are treading closely to Kiparsky’s thoughts on the matter too.) Crucially, the analysis given above does not reify any surface constraints; the facts all follow from the feed-forward derivational structure of prosodically-informed phonological theory current a decade before Prince & Smolensky.
Conclusion
While Prince & Smolensky are right to say that OT provides a principled solution to Kisseberth’s notion of conspiracies, researchers in the ’70s and ’80s treated Kisseberth’s notion as epiphenomena of acquisition (Kiparsky) or prosodic structure-building (McCarthy and contemporaries). Perhaps, then, OT do not deserve credit for solving an unsolved problem in this regard. Of course, it remains to be seen whether the many implicit conjectures in these two objections can be sustained.
