# Undissolvable Problems: things that still confuse me

Like everyone there are millions of things that I don't know. There are even millions of things I'm certain I'll never know.

But only a few of them feel fundamentally confusing.

A confusing question is one where I can't imagine how an answer could possibly actually answer the question. At a meta level I believe an answer must exist, but looking at the problem itself, it seems impossible.

Now there's two general approaches that have effectively answered such confusing problems in the past.

The first is research:

How life could possibly exist felt equally mysterious 150 years ago, and was ascribed to gods and inexplicable life forces in equal measure. Then we worked it out, and whilst there's still a lot we don't know, it no longer has that mysterious quality.

The same applies to my individual understanding of computers. As a child they seemed like magic, then once I learnt about the details of computer architecture, it made enough sense that I was willing to leave the blanks left unfilled.

The second is dissolution:

When you force yourself to understand what you're actually asking in your question, and reply "and so?" to every reductio ad absurdum, you often find you don't actually have a question anymore. You also often come out significantly more enlightened than you came in.

The classic example is the problem of free will, but you can add lots of others, like morality or decision theory. Jessicata does a great job of dissolving some particularly knotty problems, like anthropics, [here](https://www.lesswrong.com/posts/uGakMbD7QKt88oMSa/a-philosophical-kernel-biting-analytic-bullets).

But even after that some problems seem to resist such approaches, at least for now. Here's a list of problems I still find confusing. YMMV.

1.  **Why does anything exist at all?** I've heard of Tegmark's mathematical universe, but besides for the technical problems with it, it doesn't provide any motivation to assume that there would be something that it would be like to be an object in a mathematical universe (gosh that was a mouthful).
2.  **Hard problem of consciousness.** Why is there something that it's like to be me? Again much ink has been spilled on attempting to answer this question, but if an unconscious superintelligence a billion light years  away was asked to guess whether any entities had the property of there being something it would be like to be them (whatever that even means to the unconscious intelligence) there's a 0% chance it would say yes, even if it happened to explore the lines of thought of some of these purported answers.
3.  **Why is there a subjective passage of time?** To be clear, I'm not asking why time goes one way (entropy), or why entropy happens to increase only in the dimension that's time-like in the Lorentzian sense (dunno, but not confusing), but rather: if you look at the world from a 4 dimensional perspective, I trace out a world line. At any particular point on that world line I remember the past, and predict the future. But why do I then flow from that point to the next point on the world line. The obvious answer is that I don't, it just feels that way internally, but feeling is something that happens over time, not at an instant, and we're asking why I move through time in the first place. This feels like a ripe candidate for dissolution, but I haven't yet dissolved it quite correctly IMO. Again seems highly related to consciousness. Also risks ending up Boltzmann brainy, where I'm trapped in a single instance of time forever[^rsspn12ohy], thinking I'm moving but not.

There were definitely some more I thought of earlier, but it took me a while to get round to writing this post and now I seem to have forgotten them. 

Either way it seems that all my remaining problems seem highly related to consciousness. So at least I've turned 3 big problems into one really big problem 💪.
