Imagine the following scenario:
Charlie walks into a chess club, where Alice and Bob are playing a casual chess game.
Alice: Hi Charlie, do you think I should move the rook or the bishop?
Charlie: According to the Heideggerian phenomenology, chess is a process of Seinsvergessenheit which involves an individual's Existenzialien. (Blah Blah Blah) therefore there is no such a thing as 'should' and the concept of 'move' is also undefined. Also, there is no difference between a rook and a bishop.
We will suppose here that Charlie does NOT know the strategies of chess game (or any philosophy at all) and is talking in terms of philosophy (which I, personally, I admit, am not acquainted with but nonetheless genuinely respect) only to cover up his lack of knowledge. (The Heidegger stuff is just some random nonsense I put up as an example of what might be involved in this tirade.)
What is a word that can be used to describe Charlie's action in this scenario?
Thank you for your consideration.
