With any question, why is it always so helpful to know why the answer is the one that is? In another words, which principle of thinking and learning is most closely tied to question “why”? Or is it purely social act of expressing deeper interest? Is questioning for reasons mandatory?

I feel I know the answer to this question intuitively, but find it hard to express it into words without it sounding stereotypical and lazy.

This seems bizarre, because it’s children who are most “famous” for asking “why” all the time, but: How would you, say explain to a child, why do we need to know reasons behind things?
