The Hard Problem of Consciousness
philosophy · Facing Up to the Problem of Consciousness (1995)
The hard problem of consciousness, coined by David Chalmers, is the challenge of explaining why and how physical processes in the brain give rise to subjective, qualitative experience.
Core Concepts
The Problem
How does objective, physical matter produce subjective consciousness?
The Claim
Consciousness involves more than just functional or behavioral explanations; it requires either non-physical properties or a fundamental revolution in physics.
Key Evidence
- •The existence of qualia seems irreducible to third-person descriptions
- •No scientific theory has bridged the explanatory gap
Practical Implication
If the hard problem is real, a complete theory of consciousness may require new fundamental principles beyond current science.
Nuance & Limits
Some philosophers argue the hard problem is not a distinct problem but a confusion; however, it remains a central issue.
