Dissolving the question is the act of making a question no longer necessary: satisfying all associated curiosity, resolving all related confusions, but without answering the question. The classic example is the question "If a tree falls in a forest and no one hears it, does it make a sound?". The apparent paradox of the question is, in this case, resolved by pointing out the ambiguity of the term "sound". The question can be dissolved by distinguishing between "Sound" as referring to auditory experience and "Sound" as referring to vibrations in the air.
“Many philosophers—particularly amateur philosophers, and ancient philosophers—share a dangerous instinct: If you give them a question, they try to answer it.” - Eliezer Yudkowsky, Dissolving the Question
