History of the Peloponnesian War

The Athenians came to this country first to effect the conquest of Sicily, and after that, if successful, of Peloponnese and the rest of Hellas, possessing already the greatest empire yet known, of present or former times, among the Hellenes. Here for the first time they found in you men who faced their navy which made them masters everywhere; you have already defeated them in the previous sea-fight, and will in all likelihood defeat them again now.

When men are once checked in what they consider their special excellence, their whole opinion of themselves suffers more than if they had not at first believed in their superiority, the unexpected shock to their pride causing them to give way more than their real strength warrants; and this is probably now the case with the Athenians.

With us it is different. The original estimate of ourselves which gave us courage in the days of our unskillfulness has been strengthened, while the convictions super-added to it that we must be the best seamen of the time, if we have conquered the best, has given a double measure of hope to every man among us; and, for the most part, where there is the greatest hope, there is also the greatest ardor for action.
