Epistemology
The refraction (bending) of light as it passes from air into water causes an optical illusion: straws in the glass of water appear broken or bent at the water's surface.
Noam Chomsky applied rationalist ideas to language by challenging the empiricist view that the mind is a tabula rasa (blank slate) at birth. Instead, he argued that human language capacity is rooted in an innate system of concept generation and combination.12
Key aspects of his rationalist approach include:
- Innate Linguistic Endowment: Chomsky proposed that humans possess an innate faculty for language, known as Universal Grammar, which provides the structural principles common to all natural languages.34
- Plato’s Problem: He addressed the "poverty of the stimulus" argument—the observation that children acquire complex language skills with remarkable speed despite limited instruction—by positing that this knowledge must be biologically innate rather than learned through conditioning.21
- Creative Principle: Drawing on the philosophy of René Descartes, Chomsky argued that language use is "creative" rather than a causal response to environmental stimuli. He maintained that humans possess the ability to produce and understand an infinite number of novel sentences using a finite set of rules.134
- Formal Systems: He rejected behaviourist models, such as those of B.F. Skinner, in favor of formal systems that describe the underlying mental structures that make language acquisition and use possible.1
