[N]ationalism and state worship [are] the symptoms of a regression to incestuous fixation. Only when man succeeds in developing his reason and love further than he has done so far, only when he can build a world based on human solidarity and justice, only when he can feel rooted in the experience of universal brotherliness, will he have found a new, human form of rootedness, will he have transformed his world into a truly human home. (Erich Fromm)
