Some conceptual and empirical issues in linguistic theory : an illustration with pronominal clitics
(2001)
I would like to discuss a few general conceptual issues in linguistic theory, and see how they bear on some empirical facts about pronominal clitics. In particular, I would like to show that the conception of linguistic theory, justified on independent grounds, limits the class of issues and possible explanations for grammatical properties of specific linguistic expressions. I argue that this is not simply a consequence of a specific conception of grammar, conceived of as a system of principles and rules governing language, but has non-trivial empirical ramifications. Pronominal clitics are a good case study, since their grammatical properties bear on a wide range of facts falling under the purview of principles of phonology, morphology, syntax and semantics.
This paper discusses critically a number of developments at the heart of current syntactic theory. These include the postulation of a rich sequence of projections at the left periphery of the sentence; the idea that movement is tied to the need to eliminate uninterpretable features; and the conception put forward by Chomsky and others that advances in the past decade have made it reasonable to raise the question about whether language might be in some sense ‘perfect’. However, I will argue that there is little motivation for a highly-articulated left-periphery, that there is no connection between movement and uninterpretable features, and that there is no support for the idea that language might be perfect.
A pattern is a word that consists of variables and terminal symbols. The pattern language that is generated by a pattern A is the set of all terminal words that can be obtained from A by uniform replacement of variables with terminal words. For example, the pattern A = a x y a x (where x and y are variables, and the letter a is a terminal symbol) generates the set of all words that have some word a x both as prefix and suffix (where these two occurrences of a x do not overlap). Due to their simple definition, pattern languages have various connections to a wide range of other areas in theoretical computer science and mathematics. Among these areas are combinatorics on words, logic, and the theory of free semigroups. On the other hand, many of the canonical questions in formal language theory are surprisingly difficult. The present thesis discusses various aspects of the inclusion problem of pattern languages. It can be divide in two parts. The first one examines the decidability of pattern languages with a limited number of variables and fixed terminal alphabets. In addition to this, the minimizability of regular expressions with repetition operators is studied. The second part deals with descriptive patterns, the smallest generalizations of arbitrary languages through pattern languages ("smallest" with respect to the inclusion relation). Main questions are the existence and the discoverability of descriptive patterns for arbitrary languages.
The genetic code, the primary manifestation of life, and, on the other hand, language, the universal endowment of humanity and its momentous leap from genetics to civilization, are the two fundamental stores of information transmissible from the ancestry to the progeny, the molecular succession, which ensures the transfer of hereditary messages from the cells of one generation to the next generation, and the verbal legacy as a necessary prerequisite of cultural tradition. Divergent terminologies direct attention to different pattemings; and finding a logically convincing test, acceptable all around, that can determine whether one such system of terms is superior to its rivals, is often impossible. Yet the slow processes of evolution presumably apply to human societies and their symbolic systems as much as to human bodies, so that when logic cannot decide, survival eventually will.
