We learn our virtues from our friends who love us; our faults from the enemy who hates us. We cannot easily discover our real character from a friend. He is a mirror, on which the warmth of our breath impedes the clearness of the reflection.

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.
