Why Brain Activity Feels Like Something

Also called: the hard problem of consciousness

  • Open scientific debate
  • Interpretation under debate
  • Philosophical question
  • Working interpretation

Explaining how the brain works does not automatically explain why that activity comes with felt experience. I am interested in the disagreement over whether this is a deep gap in our understanding or a question asked in a misleading way.

What observation could help tell competing explanations of consciousness apart?

The idea

Imagine Mary, a scientist in a famous thought experiment by the philosopher Frank Jackson. She knows every physical fact about color vision, but she has lived her whole life in a black-and-white room. When she finally steps outside and sees something red, does she learn something new? Many people feel she does: she learns what red looks like. If so, the physical facts left something out. Others reply that Mary only gains a new ability, or a new way of knowing a fact she already had.

What I think (and don't know)

I don't know which side is right, and both have serious defenders. Some, like Chalmers, think the gap is real. Others, sometimes called illusionists, argue that the sense of a gap is itself something the brain produces, and that explaining that sense is the real task. I find the second view hard to accept and hard to dismiss.

Where it connects

This is the sharpest edge of the mystery of awareness (The Mystery of Being Aware), and the place where explaining things by their parts (Studying the Parts or the Whole) meets its strongest challenge. Some traditions come at it from another side, treating self and world as not separate (Are Self and World Really Separate?). I find that view meaningful, but it offers a different lens, not a solution brain science has confirmed. And I try to keep the line clear between what physics shows and what philosophy proposes (Where Physics Ends and Philosophy Begins).

What this does not establish

The hard problem is an open philosophical debate. It does not show that consciousness is non-physical, that minds share one awareness, or that quantum physics is involved. It also does not make brain science pointless: much of how the mind works is well studied.

Questions I'm still exploring

  • Is the hard problem a real gap, or a sign that we are asking the question the wrong way?
  • What kind of discovery would change my mind about it?
  • If the gap never closes, what follows for how I think about minds and machines?
