Sanity is not truth. Sanity is conformity to what is socially expected. Truth is sometimes in conformity, sometimes not.
Robert M. PirsigI've wondered why it took us so long to catch on. We saw it, and yet we didn't see it. Or rather we were trained not to see it. Conned perhaps into thinking that the real action was metropolitan and all this was just boring hinterland. It was a puzzling thing. The truth knocks on the door and you say, "Go away. I'm looking for the truth." And so it goes away. Puzzling.
Robert M. PirsigI think present-day reason is an analogue of the flat earth of the medieval period. If you go too far beyond it you're presumed to fall off, into insanity. And people are very much afraid of that. I think this fear of insanity is comparable to the fear people once had of falling off the edge of the world. Or the fear of heretics. There's a very close analogue there.
Robert M. PirsigThere is a perennial classical question that asks which part of the motorcycle, which grain of sand in which pile, is the Buddha. Obviously to ask that question is to look in the wrong direction, for the Buddha is everywhere. But just as obviously to ask the question is to look in the right direction, for the Buddha is everwhere.
