the world is imperilled by can-do idealists

Absolute freedom means negative freedom: a freedom from all restraint, which can see limits only as barriers to humanity, not as constitutive of it. The world is imperilled not by hard-nosed cynics who insist that nothing is possible, but by wide-eyed, ‘can-do’ idealists for whom anything is possible. Most of these are known as Americans. When the ancient Greeks encountered this kind of blasphemous overreaching, they called it ‘hubris’ and looked fearfully to the skies. And it is from the skies that it has had its tragic come-uppance.
