Noam Chomsky: Language, Cognition, and Human Potential
The Nature of Language and Cognition
Noam Chomsky explores the fundamental principles of linguistics and human cognition, emphasizing that language is an internal biological faculty rather than just an external communication tool.
• Structure Dependence: A core, universal property of human language where expressions are interpreted based on their internal structure rather than linear proximity. This is a complex computation the brain performs unconsciously.
• Internal vs. External: Language is primarily a system for internal thought. Its use in external communication is considered a marginal, albeit useful, function of the same underlying mechanism.
• Innate Faculty: Similar to how we have a specific visual system shaped by our genetic endowment, we possess a unique language faculty that defines our cognitive scope.
The Limits of Human Understanding
Chomsky challenges the notion that human intelligence can provide infinite answers, suggesting instead that our biology sets inherent boundaries on what we can comprehend.
• Scope and Limits: Our genetic endowment provides the capacity for complex reasoning and structure but simultaneously prevents us from developing incompatible systems (e.g., an insect visual system).
• Scientific Intelligibility: Drawing on the history of science, particularly the transition from the mechanical philosophy of Galileo and Newton, Chomsky argues that certain phenomena—like action-at-a-distance—demonstrate that our brains may encounter mysteries that remain fundamentally unintelligible to us.
"If we're biological organisms, which are not angels, then our capacities ought to have scope and limits, which are interrelated."
AI and Deep Learning
The discussion turns to current progress in neural networks and machine learning, with a critical eye toward their scientific utility.
• Engineering vs. Science: While tools like Google parsers are successful from an engineering standpoint as useful utilities, they do not necessarily provide scientific insight into the nature of human language.
• Pattern Recognition: Deep learning relies on finding patterns in massive datasets, which can be useful but often remains remote from the critical, hypothesis-driven nature of traditional science.
Ethics and Human Potential
Reflecting on the human condition, Chomsky discusses how institutions and nature interact.
• Instinct for Freedom: He touches on the idea that humans may possess an inherent impulse to resist illegitimate authority, contrasting with the belief that current market structures are an inevitable expression of human nature.
• Creating Meaning: Regarding the significance of life, Chomsky suggests that there is no abstract answer; meaning is something that individuals define through their own actions and engagements.
