Philip K. Dick said this quote

“ But, he thought, what does it mean, insane? A legal definition. What do I mean? I feel it, see it, but what is it?He thought, It is something they do, something they are. It is their unconsciousness. Their lack of knowledge about others. Their not being aware of what they do to others, the destruction they have caused and are causing. No, he thought. That isn't it. I don't know; I sense it, I intuit it. But -- they are purposelessly cruel... is that it? No, God, he thought. I can't find it, make it clear. Do they ignore parts of reality? Yes. But it is more. It is their plans. Yes, their plans. The conquering of the planets. Something frenzied and demented, as was their conquering of Africa, and before that, Europe and Asia.Their view; it is cosmic. Not a man here, a child there, but an abstraction : race, land. Volk. Land. Blut. Ehre. Not of honourable men but of Ehre itself, hounor; the abstract is real, the actual is invisible to them. Die Güte, but not good men, this good man. It is their sense of space and time. ”
