The great ideals of the past failed not by being outlived (which must mean over-lived), but by not being lived enough. Mankind has not passed through the Middle Ages. Rather mankind has retreated from the Middle Ages in reaction and rout. The Christian ideal has not been tried and found wanting. It has been found difficult and left untried.
Gilbert K. ChestertonThat all war is physically frightful is obvious; but if that were a moral verdict, there would be no difference between a torturer and a surgeon. There are certain intellectuals who are too bright to be content with merely praising peace but who are infuriated by anybody praising war. If no war is possible, all criminality has its chance
