Death regarding the Madness of Knowledge in "The Whereabouts"

The Madness of Knowledge (知識の狂気, Chishiki no kyōki) is one of the various madness types within the series, coming into existence due to the powerful presence of the Great Old One, Eibon.[1]


The madness is said to give the person under its influence absolute knowledge to the point where they stop thinking all together.[2] According to Franken Stein, he couldn't think straight for some reason and he felt as if his thoughts had stopped.[2]
