The episode of Guernica, with all that it represents both in the military and the moral order, seems destined to pass into History as a symbol. A symbol of many things, but chiefly of that capacity for falsehood possessed by the new Machiavellism which threatens destruction to all the ethical hypotheses of civilization. A clear example of the use which can be made of untruth to degrade the minds of those whom one wishes to convince. (Foreign Wings over the Basque Country, 1937)
