Hard[ly a] Problem

As I browse about the web, I constantly run into the infamous “hard” problem of consciousness of Chalmers in one form or another.

Sometimes the problem comes from an unexpected source – people who are materialists who actually think they have the answer to the problem. Usually the problem is thrown up by idealists or dualists who are trying to demonstrate that the materialist cannot account for his/her own consciousness, hence there is no reason to take materialism seriously.

Previously I described the “hard” problem as an “unserious” problem. Chalmers’ enumerated a number of challenging but useful areas of scientific investigation in neuroscience that he called “easy” problems. These he contrasted with the “hard” problem of explaining how experience arises from physical processes. The “easy” problems are problems amenable to scientific inquiry. The “hard” problem will never be amenable to scientific inquiry because it is asking to explain subjective experience from an objective perspective.  Let’s say we have perfected brain scans to the point that we can map absolutely every scan to subjective experience. Have we answered the “hard problem? I think not in Chalmers formulation because “there is also a subjective aspect”. You can’t explain subjectivity from the outside because it is inside the experience.

The “hard” problem, in a sense, is a gimmick, a trap for the materialist who is asked to explain subjectivity from the outside. The “hard” problem for the idealist is the really “hard” problem posed when Samuel Johnson kicked a rock and refuted Bishop Berkeley’s idealism by saying” “I refute it thus.”

Here I’d like to approach the “hard” problem is a slightly different way but one not incompatible with my previous views on the subject. Chalmers’ problem is actually of a class of problems which have no logical answer. They are meaningless problems. Let’s ask a question sometimes asked by clever children.

Why is there something rather than nothing?

We know there is no real answer to this question. We could appeal to God or something similar, but we know that just creates a new but logically equivalent question about why would there be a God rather than nothing. The only answer is a “turtles all the way down” answer.

Let’s take another question.

Why are the laws and properties of nature such that they are compatible with life and the world as we know it?

This you may recognize as the anthropic principle.  This is almost the same question as the previous one. If the laws were different, we wouldn’t be here to ask the question. Any answer – let’s try God again – leads us again into a infinite regress. If we propose X as the answer, then the question becomes: Why X?

Now let’s pose the “hard” problem.

Why am I aware?

This is not how the “hard” problem is usually presented. It is usually presented as the problem of explaining experience from physical processes. This is really the “hard” problem in its simplest form. An answer to “why am I aware” would be an answer to the “hard” problem. If I wasn’t aware, I couldn’t ask the question. If I couldn’t ask the question, I wouldn’t be aware. This is the same as “why is there something rather than nothing” question, except the “something” has been replaced with my awareness.

Idealism thinks they have solved the problem by declaring experience fundamental but that is just shifting the problem. It is like answering “why is there something rather than nothing” by declaring “something” fundamental.

The why still remains.

Because there is no answer.

Evolution, Learning, and Uncertainty

A question that has puzzled me is the one of the evolutionary reasons for consciousness. I’m speaking loosely here. Evolution doesn’t really have reasons. Changes happen in organisms because the changes in the long run bestow some advantage (or at least no disadvantage) to the survival of the organism. Let’s rephrase the question: what evolutionary advantage does consciousness provide?

Artificial Consciousness?

This is a very brief post relating to possibility of artificial consciousness on a silicon substrate. I’ve been skeptical of this and remain so, but I know both McFadden and Pockett both believe that consciousness is identical with certain types of electromagnetic fields and, therefore, the substrate these fields are created with is not relevant.

I came upon this in an interview with McFadden on medium.com.

To quote McFadden in response to a question about EM fields and computer design:

They have to be designed to be sensitive, rather than insulated from, the EM field. Remarkably, an experiment performed more than 20 years ago by the COGS group of the University of Sussex actually achieved such a feat. They evolved, rather than designed, an electrical circuit (on FPGA chips) to perform a simple task. The evolved circuit used EM interactions, as well as wired connections, to perform that task. Perhaps they inadvertently built the first artificial conscious mind. However, as far as I know, nobody has yet attempted to repeat and extend this approach but I would be very interested to hear from anyone who be willing, and would have the resources, to give it a go.

Then I found an article,  Evolving A Conscious Machine, from Discover Magazine in June, 1998.

To quote from that article about an attempt to understand why the chip seem to perform the way it did:

Thompson gradually narrowed the possible explanations down to a handful of phenomena. The most likely is known as electromagnetic coupling, which means the cells on the chip are so close to each other that they could, in effect, broadcast radio signals between themselves without sending current down the interconnecting wires. Chip designers, aware of the potential for electromagnetic coupling between adjacent components on their chips, go out of their way to design their circuits so that it won’t affect the performance. In Thompson’s case, evolution seems to have discovered the phenomenon and put it to work.

It was also possible that the cells were communicating through the power-supply wiring. Each cell was hooked independently to the power supply; a rapidly changing voltage in one cell would subtly affect the power supply, which might feed back to another cell. And the cells may have been communicating through the silicon substrate on which the circuit is laid down. The circuit is a very thin layer on top of a thicker piece of silicon, Thompson explains, where the transistors are diffused into just the top surface part. It’s just possible that there’s an interaction through the substrate, if they’re doing something very strange. But the point is, they are doing something really strange, and evolution is using all of it, all these weird effects as part of its system.
