I agree that phlogiston was not likely thought of as a mysterious answer at the time. I think that what justifies calling it a mysterious answer today is that we could justifiably notice that we are confused.
Whether it’s confusing quality is a good reason to categorize it as a mysterious answer is a different issue, however.
I agree that this is a very major problem for all of humanity. This single issue is the source of the majority of my akrasia. I stop in my tracks when I detect that I might soon be guilty of this kind of hypocrisy.
Finding a way to nail this issue down and give it a solid definition is pretty important. I’d love to contribute more on the subject, but I have SO little time right now...
Maybe later this week?
