The document discusses several key properties of human language according to Chomsky and other linguists. It describes Chomsky's view that children are born with innate, universal grammatical knowledge versus the idea that they have innate puzzle-solving abilities to acquire language. While children seem to intuitively grasp some linguistic patterns, evidence suggests they do not possess firm, innate expectations and gradually learn constraints through exposure to language. Both content and processing approaches have limitations and the acquisition process is complex.
