I doubt very much that the chief executives of any of the Fortune 500 corporations can name five edible plants, five native grasses, or five migratory birds within walking distance of their homes, or name the soil series upon which their house sits. And I would contend that if you don't know where you are, you are in fact nowhere at all.

To ask questions can become the laziest and wobbliest occupation of a mind, but when you must yourself answer the problem that you have posed, you will meditate your question with care and frame it with precision.
