Georg Wilhelm Friedrich Hegel — "The Absolute is Mind."

"The finite is the non-existent."

"The history of the world is not the theatre of happiness. Periods of happiness are blank pages in it, for they are periods of agreement, periods when the antithesis is in abeyance."

"The world spirit is a spirit that does not suffer itself to be confined to one nation, but passes from nation to nation, from period to period."

"The owl of Minerva spreads its wings only with the falling of the dusk."

"What experience and history teach is this — that peoples and governments never have learned anything from history, or acted on principles deduced from it."
