Thucydides, The Peloponnesian War "We throw open our city to the world, and never by alien acts exclude foreigners from any opportunity of learning or observing, although the eyes of an enemy may occasionally profit by our liberality; trusting less in system and policy, than to the native spirit of our citizens;" (The Funeral Oration of Pericles, Book II, 39) Submitted by: abl@cybill.inesc.pt (Antonio Leal)
