Summary of ""What is Language and Why Does It Matter" - Noam Chomsky"
Summary of "What is Language and Why Does It Matter" by Noam Chomsky
Main Ideas and Concepts:
- Language as a Biological and Cognitive Phenomenon: Chomsky situates language study within a psychobiological framework, emphasizing that language is a property of the individual mind/brain, not just a social or communicative tool. This approach revives rationalist traditions and applies formal, computational, and scientific methods to understand human cognition.
- The Basic Property of Language:
Language generates an unbounded (infinite) array of hierarchically structured expressions that map to two interfaces:
- The sensory-motor system (externalization, e.g., speech or sign)
- The conceptual-intentional system (internal thought)
- Generative Grammar and Internal Language (I-language): Each individual has an internal, computational system (I-language) that generates these expressions. The theory aims to uncover the computational procedures (Generative Grammar) that produce this infinite set.
- Minimalist Program and Merge Operation:
Chomsky highlights the Minimalist Program, which seeks the simplest and most general computational mechanisms underlying language. The fundamental operation is merge, a binary set-formation operation that combines two elements into a new syntactic object.
- External Merge: Combining two separate elements.
- Internal Merge: Displacement phenomena (e.g., "Which book did John read?") arise naturally as internal merge, not as exceptions or complications.
- Structure Dependence vs. Linear Order: Language rules depend on hierarchical structure rather than linear order. Children acquire these rules despite limited or no direct evidence, indicating innate principles (Universal Grammar, UG). The preference for minimal structural distance over minimal linear distance is a key design feature of language, supported by neurological evidence.
- Language as an Instrument of Thought, Not Primarily Communication: Contrary to common assumptions, Chomsky argues that language’s primary function is to serve thought (conceptual-intentional interface). Communication is a peripheral, ancillary use of language. This challenges widespread views that see language primarily as a communication system.
- Evolutionary Perspective: The emergence of language was a recent, abrupt event (50,000-100,000 years ago) linked to the development of this unique computational capacity. There has been little evolutionary change since then.
- Critique of Usage-Based and Communication-Centered Approaches: Chomsky critiques approaches focusing solely on language as communication or statistical learning from data, arguing they fail to address the core computational properties and innate principles of language.
- Scientific Methodology and Linguistics: Emphasizes the importance of theoretical simplicity, explanatory power, and unification with natural sciences in linguistic theory. Rejects the notion that exceptions invalidate universal principles, drawing parallels with other sciences.
- Competence vs. Performance: The talk primarily concerns linguistic competence (knowledge of language) rather than performance (actual language use), although performance is recognized as influenced by memory and other cognitive constraints.
- Open Questions and Research Directions:
- Internal dialogue and non-externalized language use remain understudied.
- The mechanisms of language acquisition, brain implementation, and interfaces with other cognitive systems are ongoing research areas.
- The nature of ungrammaticality is complex and not a strict binary distinction.
Detailed Methodological and Instructional Points
- Understanding Language:
- Recognize language as an internal, individual property (I-language), not just a social or communicative phenomenon.
- Study language using formal, computational, and experimental methods aligned with natural science principles.
- Key Theoretical Constructs:
- Define the basic property of language as the generation of infinite hierarchical expressions.
- Model this with Generative Grammar, focusing on the computational procedure rather than enumerated sets of sentences.
- Adopt the Minimalist Program to seek the simplest explanatory mechanisms, primarily the Merge Operation.
- Merge Operation:
- Treat merge as a binary, unordered set formation combining two syntactic objects.
- Distinguish between:
- External merge: Combining distinct elements.
- Internal merge: Re-merging an element already part of a structure, explaining displacement.
- Avoid introducing unnecessary operations like "copy" or "remerge" beyond merge itself.
- Principle of Minimal Computation:
- Language computation prefers minimal structural complexity and avoids unnecessary modifications or ordering.
- This principle explains phenomena like displacement and deletion of copies in surface forms.
- Structure Dependence:
- Understand that syntactic rules depend on hierarchical structure, not linear order.
- Recognize this as a universal property of natural languages and a key to language acquisition.
