“The Owl of Minerva takes flight only as the dusk begins to fall.” Or, to speak more directly than G W F Hegel, we can only become wise about the direction of history late in the day. The aphorism is pertinent to the euro crisis. Is this the twilight hour for the single currency or are the clouds over the euro no more than an early morning mist in pan-European history? The euro’s fate will look inevitable in retrospect (that is Hegel’s point), but for now the balance of historical forces is far from clear.
