From UG to the Biolinguistic Program

Introduction The acquisition of language is one of the most remarkable cognitive achievements of humans, yet it raises profound questions about the nature of knowledge and learning. This article explores Noam Chomsky’s response to “Plato’s Problem,” a concept popularized by Bertrand Russell, which questions how humans can know so much given their limited experiences.
