Why is "Why is the sky blue?" such a common question made by children? And why has that question about the question never been asked before?
Is it that the question is just a cultural artifact, that is, that someone remarked on one child somewhere actually asking that question once, and once written others pick up on the humor of such a deep philosophical question coming from someone so young, and then the humor being propagated through our current culture by the media?
Though many children do go through a 'why' stage, do most children go through this, if not verbally, at least psychologically? And is this cross-cultural?
As a side question, is the question "Why is the sky blue?" truly a question that can be answered by 'why'? Is it really asking for an event sequence description or is it misplacedly asking for a motivated causality (expecting of all events to be initiated by an actor)?
