The fact that a question can be phrased does not guarantee the world contains an answer in that form.

Grammar is more permissive than reality. You can build a perfectly formed sentence ending in a question mark that has no answer of that shape, because it presumes a category or a sharp line that the world does not provide. The sentence’s smoothness gives no evidence about whether there is anything there to find.

When a question has been troubling you for a long time, test whether it has a real referent. Ask what an answer would even look like, in concrete terms. If you cannot describe what would count as one, the honest next step is to reshape the question rather than continue searching for something that was never out there.
