Unexamined

The unexamined life is not worth living.

We may leave the details of their theory unexamined, but we must not forget to ask them the only question with which we are concerned: Are all things in motion and flux?

If, as Socrates said, "The unexamined life is not worth living," then we should also consider a corollary to this axiom about life in school: "The unexamined lesson is not worth learning!"
