Difference between unknowable and solvable

“But the wonderful thing about unanswerable questions is that they are always solvable, at least in my experience. What went through Queen Elizabeth I’s mind, first thing in the morning, as she woke up on her fortieth birthday? As I can easily imagine answers to this question, I can readily see that I may never be able to actually answer it, the true information having been lost in time. On the other hand, “Why does anything exist at all?” seems so absolutely impossible that I can infer that I am just confused, one way or another, and the truth probably isn’t all that complicated in an absolute sense, and once the confusion goes away I’ll be able to see it. This may seem counterintuitive if you’ve never solved an unanswerable question, but I assure you that it is how these things work. Coming next: a simple trick for handling “wrong questions.”” (Eliezer Yudkowsky, Rationality)
