Full Idea
Some philosophers focus on the so-called 'pragmatics of explanation' - that an explanation is an answer to a 'why' question, and the relevant answer will depend on the presuppositions or interests of the questioner.
Clarification
Pragmatics concern how things actually work
Gist of Idea
Maybe explanation is entirely relative to the interests and presuppositions of the questioner

A Reaction
This seems to me right. Explanation is an entirely human business, not a feature of nature, and most explanations will track back to the big bang if you have the patience, but they always terminate because of pragmatic considerations. But fobbing off?
