“Old men who never cheated, never doubted,
Communicated monthly, sit and stare
At the new suburb stretched beyond the run-way
Where a young man lands hatless from the air.”

“The triumphs of peace have been in some proximity to war. Whilst the hand was still familiar with the sword-hilt, whilst the habits of the camp were still visible in the port and complexion of the gentleman, his intellectual power culminated; the compression and tension of these stern conditions is a training for the finest and softest arts, and can rarely be compensated in tranquil times, except by some analogous vigor drawn from occupations as hardy as war.”
—Ralph Waldo Emerson (18031882)
