Like Plato, Žižek uses allusions to the unclean to alert the reader to how repugnant, discordant facts can undercut a particular vision of reality. He also expands the use of the metaphor of filth to call our attention to something else closer to his heart: the failings of our modern political discourse. Bacon warned us of intellectual intemperance, but Žižek uses references to the unclean to warn us of modern political intemperance. In the cases of Plato, Bacon and Žižek, the philosophical issue raised is about boundaries and the implications of transgressing them.
In the unclean, Žižek finds the ultimate metaphor for the dumbing down of political thought and speech, a way of understanding the collapse of modern political discourse – itself an echo of Plato’s critique of the false, that is, ‘sophistical’ use of political language – in which ‘public vulgarity’ is used without shame.
He begins his argument with a scene from a surreal film from 1974 in which people at a dinner party defecate in public:
We probably all remember the scene from Luis Buñuel’s The Phantom of Liberty in which relations between eating and excreting are inverted: people sit at their toilets around the table, pleasantly talking, and when they want to eat, they silently ask the housekeeper: ‘Where is that place, you know?,’ and sneak away to a small room in the back.
Political figures today, Žižek argues, are committing the verbal equivalent of this public defecation. They are violating traditional, unwritten rules and boundaries that are used to guide public conduct by making outrageous statements that were once taboo. ‘They are a clear sign of the regression of our public sphere,’ he writes in Newsweek in 2016. ‘Accusations and ideas that were till now confined to the obscure underworld of racist obscenity are now gaining a foothold in official discourse.’ And citing Georg Hegel’s notion of Sittlichkeit – the ‘the thick background of (unwritten) rules of social life … that tell us what we can and cannot do’, Žižek further observes that ‘These [unwritten] rules are disintegrating today: what was a couple of decades ago simply unsayable in a public debate can now be pronounced with impunity.’
A discharge of verbal political filth has changed the public sphere into a kind of collective public toilet for language users – lurid speeches full of nasty ignorance, blatant vulgarity and raw prejudice. Plato and Žižek, with some tacit support from Bacon, use the notion of the unclean in similar ways to offer, implicitly, practical advice about how humans should conduct themselves: be wary of intemperately overstepping limits by chasing overweening ambitions, whether intellectual or political, which soil clear thinking and logic, and/or corrupt language, politics and ethics. Discussions of lowly filth, and all of its disgusting variations, are not merely the province of vulgarians, but seem to offer life lessons for everyone, not just philosophers.
