I'm thinking more of an objective madness, not a socially defined madness.
Specifically, a derangement of perspective and an absence of awareness of it.
Like (to use an absurd example) if you pressed your face up to a beige wall, focusing intensely upon it.
You might be convinced that the whole universe is beige, and all evidence would support you in this conclusion. But you would be wrong of course.
Sure. But we're just semanticizing over what constitutes minor details.
I mean we might agree that authority speaks truth but differ on who the authority is. I'd call the former the substantial thought and the latter the detail.
