Stories that leave
the question open
These are not made-up examples. Every one of them is a real story that someone told a long time ago to make a point — a myth, a parable, a puzzle. We have retold them plainly for young readers and written down where each one comes from. None of them ends in an answer.

How to read one
- Read it out loudThese were spoken long before they were written. They work better as something you tell.
- Stop before the endEvery story page gives you the place to stop and ask, and what to ask.
- Do not settle itA story that ends in a tidy answer teaches that thinking is a race to a finish line.
