History of the Peloponnesian War

Ath.Hope, the comfort of danger, when such use it as have to spare, though it hurt them, yet it destroys them not. But to such as set their rest upon it (for it is a thing by nature prodigal), it at once by failing maketh itself known; and known, leaveth no place for future caution.

Which let not be your own case, you that are but weak and have no more but this one stake. Nor be you like unto many men, who, though they may presently save themselves by human means, will yet, when upon pressure of the enemy their most apparent hopes fail them, betake themselves to blind ones, as divination, oracles, and other such things which with hopes destroy men.
