I can see in the acorn the oak tree. I see the growth, the rebuilding, the restoring. I see that is the American psyche. There is so much we can draw understanding from. One of the lessons is the development of courage. Because without courage, you can't practice any of the other virtues consistently.
We have come out of the time when obedience, the acceptance of discipline, intelligent courage and resolution were most important, into that more difficult time when it is a man's duty to understand his world rather than simply fight for it.
