The Mind–Machine Question

Can a machine think, understand, or be conscious? This sub-article expands Section 1.1 of Philosophy.

The Turing Test (1950)

• A behavioral criterion: a machine is intelligent if its conversation is indistinguishable from a human’s.
• Critiques: it tests behavior, not understanding or experience.

The Chinese Room (Searle, 1980)

• A system that manipulates symbols by rules may simulate intelligence without understanding.
• Argument: syntax alone does not yield semantics.

Functionalism

• Mental states are defined by causal roles, not substrate.
• A properly organized silicon system could, in principle, be a mind.

The Hard Problem of Consciousness

• David Chalmers distinguishes easy problems (function) from the hard problem (subjective experience).
• Does a computer have qualia? Unresolved.

Why It Matters

The answer shapes whether AI is “just a tool” or a moral subject, and guides expectations about AGI.
