"It is impossible to conceive of fascism or Stalinism without propaganda - but capitalism can proceed perfectly well, in some ways better, without anyone making a case for it. Žižek's counsel here remains invaluable. 'If the concept of ideology is the classic one in which the illusion is located in knowledge', he argues, 

'then today's society must appear post-ideological: the prevailing ideology is that of cynicism; people no longer believe in ideological truth; they do not take ideological propositions seriously. The fundamental level of ideology, however, is not of an illusion masking the real state of things but that of an (unconscious) fantasy structuring our social reality itself. And at this level, we are of course far from being a post-ideological society. Cynical distance is just one way ... to blind ourselves to the structural power of ideological fantasy: even if we do not take things seriously, even if we keep an ironical distance, we are still doing them.'

Capitalist ideology in general, Žižek maintains, consists precisely in the overvaluing of belief - in the sense of inner subjective attitude - at the expense of the beliefs we exhibit and externalize in our behavior. So long as we believe (in our hearts) that capitalism is bad, we are free to continue to participate in capitalist exchange. According to Žižek, capitalism in general relies on this structure of disavowal. We believe that money is only a meaningless token of no intrinsic worth, yet we act as if it has a holy value. Moreover, this behavior precisely depends upon the prior disavowal - we are able to fetishize money in our actions only because we have already taken an ironic distance towards money in our heads."

I feel guilty seeing Žižek here after his betrayal of the refugees.  Fisher has left no 'choice' for me, but to faithfully post what he constructed.
