What Questions Reveal
Questions show what is still open, but they also show what has already been taken as settled.
Consider: "Who broke the glass?"
The identity remains open.
But the question already contains a substantial commitment: somebody broke the glass.
If nobody did, the question has organized the situation badly.
"What happened?"
This already treats something as an event that can be picked out and described.
"Where did it happen?"
This relies on a spatial organization in which something can be located.
"When?"
This relies on an ordered temporal structure.
"How did it happen?"
This may ask for a process, mechanism, or sequence.
"Why?"
That can do several different jobs.
"Why did the bridge collapse?"
"Why did you leave?"
"Why should we accept this?"
"Why does this keep happening?"
These questions may be asking about a cause, a motive, a justification, or some other connection that would make the situation intelligible.
An intelligible question depends on much that is not being questioned. It marks something as open while also revealing parts of the surrounding orientation that remain stable enough for the question to make sense.
An answer can shift inquiry into another part of the background structure on which the question depends.
"Why did the bridge collapse?"
The material failed.
"Why did the material fail?"
The materials were mixed incorrectly during manufacturing.
The first question concerned the collapse. Its answer connects that event to another process that had remained in the background, and that process can now become the object of inquiry in turn.
In a narrative context, this may amount to moving from one part of a background story to another. In other cases, inquiry may move into a procedure, a classification, a measurement practice, an assumption, or another part of orientation.
