What is the purpose and methodology of the Minimalist Program in linguistic theory?

The Minimalist Program (MP) is a linguistic theory proposed by Noam Chomsky in the 1990s that aims to simplify and refine the principles and parameters framework of his earlier work. The MP seeks to answer the fundamental question of what constitutes a human language and how it is acquired and used. It also aims to provide a universal and minimal set of principles and structures that can account for the vast diversity of languages in the world. In this introduction, we will explore the purpose and methodology of the Minimalist Program in linguistic theory, and its significance in understanding the nature of language and human cognition.

In linguistics, the Minimalist Program (MP) is a major line of inquiry that has been developing inside Generative Grammar since the early nineties. It started with a 1993 paper by Noam Chomsky.

Chomsky presents MP as a program, not as a theory, following Imre Lakatos’s distinction. The MP seeks to be a mode of inquiry characterized by the flexibility of the multiple directions that its minimalism enables. Ultimately, the MP provides a conceptual framework used to guide the development of grammatical theory. For Chomsky, there are minimalist questions, but the answers can be framed in any theory. Of all these questions, the one that plays the most crucial role is this: why language has the properties it has. That said, the MP lays out a very specific view of the basis of syntactic grammar that, when compared to other formalisms, is often taken to look very much like a theory.

 

Theoretical goals

Perfection

The MP appeals to the idea that the language ability in humans shows signs of being incorporated under an optimal design with exquisite organization, which seems to suggest that the inner workings conform to a very simple computational law or a particular mental organ. In other words, the MP works on the assumption that Universal Grammar constitutes a perfect design in the sense that it contains only what is necessary to meet our conceptual, and physical (phonological) needs.

From a theoretical standpoint, and in the context of generative grammar, the MP draws on the minimalist approach of the Principles and Parameters program, considered to be the ultimate standard theoretical model that generative linguistics has developed since the eighties. What this approach suggests is the existence of a fixed set of principles valid for all languages, which, when combined with settings for a finite set of binary switches (parameters), may describe the specific properties that characterize the language system a child eventually comes to attain.

The MP aims to get to know how much of the Principles and Parameters model can be taken as a result of this hypothetical optimal and computationally efficient design of the human language faculty. In turn, more developed versions of the Principles and Parameters approach provide technical principles from which the MP can be seen to follow.

 

Economy

The MP aims at the further development of ideas involving economy of derivation and economy of representation, which had started to become significant in the early 1990s, but were still peripheral aspects of Transformational grammar.

Economy of derivation is a principle stating that movements (i.e. transformations) only occur in order to match interpretable features with uninterpretable features. An example of an interpretable feature is the plural inflection on regular English nouns, e.g. dogs. The word dogs can only be used to refer to several dogs, not a single dog, and so this inflection contributes to meaning, making it interpretable. English verbs are inflected according to the number of their subject (e.g. “Dogs bite” vs “A dog bites”), but this information is only interpretable once a relationship is formed between the subject and the verb, so movement of the subject is required.

Economy of representation is the principle that grammatical structures must exist for a purpose, i.e. the structure of a sentence should be no larger or more complex than required to satisfy constraints on grammaticality, which are equivalent to constraints on the mapping between the conceptual/intensional and sensori-motor interfaces in the optimal system that minimalism seeks to explore.

 

Technical innovations

The exploration of minimalist questions has led to several radical changes in the technical apparatus of transformational generative grammatical theory. Some of the most important are:

  • The generalization of X-bar Theory into Bare Phrase Structure (see below).
  • The simplification of representational levels in the grammatical model, eliminating the distinction between Deep Structure and Surface Structure in favor of more explicitly derivational approach.
  • The elimination of the notion of government.
  • The inclusion of a single point of interaction between syntax and the interfaces (conceptual/intensional and sensori-motor), commonly called the point of Spell-Out.
  • The idea that syntactic derivations proceed by clearly delineated stages called phases (see below).

 

Bare Phrase Structure

A major development of MP inquiry is Bare Phrase Structure (BPS), a theory of phrase structure (sentence building prior to movement) developed by Noam Chomsky.

This theory contrasts with X-bar theory, which preceded it, in four important ways:

  • BPS is explicitly derivational. That is, it is built from the bottom up, bit by bit. In contrast, X-Bar Theory is representational – a structure for a given construction is built in one fell swoop, and lexical items are inserted into the structure.
  • BPS does not have a preconceived phrasal structure, while in X-Bar Theory, every phrase has a specifier, a head, and a complement.
  • BPS permits only binary branching, while X-Bar Theory permits both binary and unary branching.
  • BPS does not distinguish between a “head” and a “terminal”, while some versions of X-Bar Theory require such a distinction.

BPS incorporates two basic operations: Merge and Move. Although there is active debate on exactly how Move should be formulated, the differences between the current proposals are relatively minute. The following description follows Chomsky’s original proposal.

Merge is a function that takes two objects (say α and β) and merges them into an unordered set with a label (either α or β, in this case α). The label identifies the properties of the phrase.

Merge (α, β) -> {α, {α, β}}

For example, Merge can operate on the lexical items ‘drink’ and ‘water’ to give ‘drink water’. Note that the phrase ‘drink water’ behaves more like the verb ‘drink’ than like the noun ‘water’. That is, wherever we can put the verb ‘drink’ we can usually put the phrase ‘drink water’:

I like to _____________ (drink)/(drink water).
(Drinking/Drinking water) __________ is fun.

Furthermore, we typically can’t put the phrase ‘drink water’ in places where we can put the noun ‘water’:

We can say “There’s some water on the table”, but not “There’s some drink water on the table”.

So, we identify the phrase with a label. In the case of ‘drink water’, the label is ‘drink’ since the phrase acts as a verb. For simplicity, we call this phrase a verb phrase or VP. Now if we were to Merge ‘cold’ and ‘water’ to get ‘cold water’, then we would have a noun phrase or NP with the label ‘water’. The reader can verify that the phrase ‘cold water’ can appear in the same environments as the noun ‘water’ in the three test sentences above. So, for ‘drink water’ we have the following:

Merge (drink, water) -> {drink, {drink, water}}

Merge can also operate on structures already built. If it couldn’t, then such a system would predict only two-word utterances to be grammatical. Say we Merge a new head with a previously formed object (a phrase).

Merge (γ, {α, {α, β}}) -> {γ, {γ, {α, {α, β}}}}

Here, γ is the label, so we say that γ ‘projects’ from the label of the head.

Note crucially that Merge operates blindly, projecting labels in all possible combinations. The subcategorization features of the head then license certain label projections and eliminate all derivations with alternate projections.

 

Phases

A phase is a syntactic domain first hypothesized by Noam Chomsky in 1998. A simple sentence is often decomposed into two phases, CP and vP (see X-bar theory). Movement of a constituent out of a phase is (in the general case) only permitted if the constituent has first moved to the left edge of the phase. This condition is described in the Phase Impenetrability Condition, which has been variously formulated within the literature. In its original conception, only the vP in transitive and unergative verbs constitute phases. The vP in passives and unaccusative verbs (if even present) are not phases. This topic is, however, currently under debate in the literature.

 

Criticism

In the late 1990s, David E. Johnson and Shalom Lappin published the first detailed critiques of Chomsky’s minimalist program. This technical work was followed by a lively debate with proponents of minimalism on the scientific status of the program. The original article provoked several replies and two further rounds of replies and counter-replies in subsequent issues of the same journal. Lappin et al. argue that the Minimalist Program is a radical departure from earlier Chomskian linguistic practice that is not motivated by any new empirical discoveries, but rather by a general appeal to “perfection” which is both empirically unmotivated and so vague as to be unfalsifiable. They compare the adoption of this paradigm by linguistic researchers to other historical paradigm shifts in natural sciences and conclude that the adoption of the Minimalist Program has been an “unscientific revolution”, driven primarily by Chomsky’s authority in linguistics. The several replies to the article in Natural Language and Linguistic Theory Volume 18 number 4 (2000) make a number of different defenses of the Minimalist Program. Some claim that it is not in fact revolutionary or not in fact widely adopted, while others agree with Levine and Johnson on these points, but defend the vagueness of its formulation as not problematic in light of its status as a research program rather than a theory (see above).
