Insanity on the other hand is an intellectual pattern. It may have biological causes but it has no physical or biological reality. No scientific instrument can be produced in court to show who is insane and who is sane. There's nothing about insanity that conforms to any scientific law of the universe. The scientific laws of the universe are invented by sanity. There's no way by which sanity, using the instruments of its own creation, can measure that which is outside of itself and its creations. Insanity isn't an 'object' of observation. It's an alteration of observation itself. There's no such thing as a 'disease' of patterns of intellect. There's only heresy. And that's what insanity really is.
