Foucault should be a reminder that the culture wars are not new and post-truth can’t exist because there was never a truth at the start. This is similar to Latour’s question asking if we’ve ever been modern. And the answer remains ‘no’. There is no post-truth as there is no post-modern as each of these is predicated on a fantastical claim. Many humans defend the notion of truth, but they are fighting windmills.
“We are therefore at war with one another; a battlefront runs through the whole of society, continuously and permanently, and it is this battlefront that puts us all on one side or the other. There is no such thing as a neutral subject. We are all inevitably someone’s adversary.”— Michel Foucault, Society Must Be Defended
In these culture wars, each side is fighting for its version of the truth. The truth of rights and freedoms and the correct construct of societies. But there is not one culture war. There are myriad culture wars, and there are few opportunities to be allied across all of these dimensions with another person. For the congruent dimensions, one needs to operate in the mode of the enemy of my enemy is my friend whilst deciding how to ally on other disagreed dimensions later.
But never forget that the wars are intentional. They are a feature of the system of normalisation, not a bug. More importantly, don’t think for a moment that your truth is the truth. The same goes for your adversary.
