The Consciousness Rabbit Hole

There is a great video on the subject here. It's illustrative of the "rabbit hole" we go down when trying to "explain" something. Ultimately, this is the same rabbit hole we go down when we try to "explain" anything. "What is consciousness'' has the same problems as "What is gravity?". Any "explanation" would be another description, requiring a certain amount of hand waving to count as pulling the curtain back.

Toward the end, there is a discussion of the difference between "thoughts" and "reality." The problem is framing the issue as a "problem" to be solved. The "problem" can be reduced to the collapse of the wave function (see below). This is not to say we are not left with a mystery. It's just that it has nothing to do with "consciousness".

For me, conscousness is a side issue. Certainly, consciousness is a vast mystery - perhaps THE mystery. But we don't need to have a solution to this mystery to know that the world we experience is created in our brains. Trivially, experience is experience.

"Consciousness" bites off too much of the mystery. It's a matter of information about the world versus the world itself. We can make this distinction if we are talking about robots or bees. The mystery of consciousness can be set aside.

At a fundamental level, quantum mechanics tells us two things:

  • "Properties" of the world do not exist when not measured. Einstein disagreed, and he was wrong. See "EPR Paradox".
  • The information you can extract from a particle depends on what you are looking for. Precision in one question inevitably results in a lack of precision in another.
A "Scientific" view would assume that the above issues would be true of any information system about the world - consciousness or not. For example, when a mechanical experimental setup is left to do measurements.

This would seem to be a fundamental separation between any kind of "observer" and the actual universe, even if the "observer" is something as simple as a kind of "macro" scale object that produces an "up or down" result.

In the above video, Roger Penrose draws attention to this fundamental idea: the "collapse of the wave function." But he does a lot of "hand waving" to connect the idea to consciousness. His hand-waving wanders off to the area of "microtubules", which have the advantage of being a little understood. Even if he's right, we are still stuck with the "hard problem".
