"I believe there is no other difference between those who are called courageous and those who are branded craven than that the second are fearful before the danger and the first after it. No one can be much frightened, certainly, during a period of great and immanent peril -- the mind is too much concentrated on the thing itself, and on the actions necessary to meet or avoid it. The coward is a coward, then, because he has brought his fear with him; persons we think cowardly will sometimes amaze us by their bravery, if they have had no forewarning of their danger."
