Oh no, this is a tragedy! He died before I got to explain private languages!

Wittgenstein wrote much of the Tractatus Logico-Philosophicus in the trenches in World War I, where he fought on the German side. The argument that he is giving is his argument that you cannot have negative knowledge of what exists, because in order to do so you would have to have complete knowledge of what does exist, and a further piece of knowledge that you had all the knowledge there was to be had, which is impossible. He famously refused to say that he know for certain that a Hippo was not in the room, in an argument with Bertrand Russell.

"And how do you plead to the charge of obscurantism?"

"The theory of a 'plea' is organized, understood, and experienced prior to any conscious intention as a theory of language. Before we constructed signs we have a presupposed theory of both implicit thought, grasped as pure presentness, and explicit language, grasped as an obliteration of all signs and structures of thought. These two modes must come together in an infinite manifold in order for any 'plea' to be made."

"God damnit Derrida, come on."

See the explanation on comic 182, it's a similar idea.

Camus: "Wait, so if the meaning of life is arbitrary, maybe it can just be seducing as many girls as possible?"

Sartre: "It isn't that arbitrary."

It's like that show "It's Always Sunny in Philadelphia", but instead of a gang of nihilistic, uneducated narcissists it is a gang of nihilistic, educated narcissists.

"Wait a minute...what if there is some kind of evil demon who is deceiving me into thinking God is necessarily good? Oh yeah, that's right, God wouldn't let that happen because he is necessarily good."
