I think it is possible to outline a list of features that are typical of what I would like to call Ur-Fascism, or Eternal Fascism. These features cannot be organized into a system; many of them contradict each other, and are also typical of other kinds of despotism or fanaticism. But it is enough that one of them be present to allow fascism to coagulate around it.
even though political regimes can be overthrown, and ideologies can be criticized and disowned, behind a regime and its ideology there is always a way of thinking and feeling, a group of cultural habits, of obscure instincts and unfathomable drives
