“If, in addition, one imagines not only that airplanes fly through the airspace over land and sea but also that radio waves from transmissions from all lands circle the globe uninterruptedly through the atmospheric space, then it would be easy to believe now not only that a new, third dimension has been achieved but also that even a third element has been added, the air, as a new elementary domain of human existence. To both the mythic beasts, Leviathan and Behemoth, a third would be added, a great bird. But we must not be overhasty with such consequential propositions. Indeed, if one thinks of the mechanized technical means and energies with which human power is exercised in airspace, and if one recognizes the explosive motors by means of which air machines are moved, then it appears that it is the fire that is the additional, genuinely new element of human activity.”
—Carl Schmitt, Land and Sea: A World-Historical Meditation
