Kant argued that reason would bring about perpetual peace in a benign global political order. Another great philosopher, Bertrand Russell, saw things rather differently when asked about the prospects for world peace:

“After ages during which the earth produced harmless trilobites and butterflies, evolution progressed to the point at which it has generated Neros, Genghis Khans, and Hitlers. This, however, I believe is a passing nightmare; in time the earth will become again incapable of supporting life, and peace will return.”

I don’t presume to enter those ranks. I’d like to think that humans have the capacity to do much better than what Russell forecast, even if not to achieve Kant’s ideal.
