汤姆•佩恩，这位伟大的美国革命者和《人类的权利》一书的作者写道 ： “ 想确保自身自由的人甚至必须保卫他的敌人也不受压迫；因为如果他违反了这项义务，就建立了一个会使他自己承受同样后果的先例。
Tom Paine, the great American revolutionary and author of The Rights of Man, wrote: “He that would make his own liberty secure must guard even his enemy from oppression; for if he violates this duty he establishes a precedent that will reach himself.”
