It is a head scratcher. These "intellectuals" seem to believe in the absurd.
My theory is that there is a glut of people wanting to be "intellectuals" and academics and that pretty much every possible and rational concept has already been written about and pondered for the past 500 years. So how do you make a name for yourself when there is nothing left to 'discover'? You simply talk jibberish with a loud and confident voice and the masses will start thinking that it is their own inadequacies preventing them seeing the wisdom of the intellectual.
