A spotters guide
Their problem will be, rather, with the shades of obliviousness. Here our future scholars will have to try to distinguish between three kinds of ignorance: deliberate unknowing, crass self-delusion and what we can only call pig ignorance. So, for their benefit, here is a brief spotters guide.
Deliberate unknowing is when you are fully aware of something but then choose to suppress that consciousness. A good example is Theresa May speaking about the Irish border on June 21st 2016, just two days before the referendum: Just think about it. If we are out of the European Union with tariffs on exporting goods into the EU, thered have to be something to recognise that, between Northern Ireland and the Republic of Ireland. And if you pulled out of the EU and came out of free movement, then how could you have a situation where there was an open border with a country that was in the EU and has access to free movement? So she knew full well that a Brexit that involved leaving the customs union would create a hard border. And then, as prime minister, she insisted on the opposite: that a hard Brexit was perfectly compatible with no return of a hard border. She unknew what she had known.
And then theres pig ignorance the genuine hallmarked, unadulterated, slack-jawed, open-mouthed, village idiot variety. Crass self-delusion is when you start with an ideological premise that you believe to be true even though it isnt and then draw apparently reasonable conclusions from it.
Thus, for example, David Davis sincerely believed the EU is just a front for German domination of Europe. Hence he also believed quite genuinely that the Brexit negotiations would be conducted not with Brussels but over a convivial weissbräu and schnitzel in Berlin and that frictionless trade would be decreed immediately because the German car manufacturers wished it so: sincerely fatuous self-delusion.
Village idiot
And then theres pig ignorance the genuine hallmarked, unadulterated, slack-jawed, open-mouthed, village idiot variety in which the people who are in charge of the British state dont know stuff that anyone off Gogglebox could tell them. The Brexiteer MP Nadine Dorries admitted in effect that she didnt know what a customs union is. Her comrade Andrew Bridgen said last month: As an English person, I do have the right to go over to Ireland and I believe that I can ask for a passport. Cant I?
