Mystery.

Zwerger, from The Little Mermaid, 2004

All my life I've been harassed by questions: Why is something this way and not another? How do you account for that? This rage to understand, to fill in the blanks, only makes life more banal. If we could only find the courage to leave our destiny to chance, to accept the fundamental mystery of our lives, then we might be closer to the sort of happiness that comes with innocence.  Somewhere between chance and mystery lies imagination, the only thing that protects our freedom, despite the fact that people keep trying to reduce it or kill it off altogether.
