Politically speaking, tribal nationalism [patriotism] always insists that its own people are surrounded by 'a world of enemies' - 'one against all' - and that a fundamental difference exists between this people and all others. It claims its people to be unique, individual, incompatible with all others, and denies theoretically the very possibility of a common mankind long before it is used to destroy the humanity of man.
Hannah ArendtIdeological thinking becomes emancipated from the reality that we perceive with our five senses, and insists on a 'truer' reality concealed behind all perceptible things, dominating them from this place of concealment and requiring a sixth sense that enables us to become aware of it.
