3o of Europe's top intellectuals, including philosophers and Nobel-prize-winner authors, have written a manifesto defending Europe against the rise of nationalist populism.  Read it here.  Some excerpts:

Europe is being attacked by false prophets who are drunk on resentment, and delirious at their opportunity to seize the limelight. It has been abandoned by the two great allies who in the previous century twice saved it from suicide; one across the Channel and the other across the Atlantic. The continent is vulnerable to the increasingly brazen meddling by the occupant of the Kremlin. Europe as an idea is falling apart before our eyes.

And

Our faith is in the great idea that we inherited, which we believe to have been the one force powerful enough to lift Europe’s peoples above themselves and their warring past. We believe it remains the one force today virtuous enough to ward off the new signs of totalitarianism that drag in their wake the old miseries of the dark ages. What is at stake forbids us from giving up.
