It was the ghost of rationality itself ... This is the ghost of normal everyday assumptions which declares that the ultimate purpose of life, which is to keep alive, is impossible, but that this is the ultimate purpose of life anyway, so that great minds struggle to cure diseases so that people may live longer, but only madmen ask why. One lives longer in order that he may live longer. There is no other purpose. That is what the ghost says.
Robert M. PirsigWho really can face the future? All you can do is project from the past, even when the past shows that such projections are often wrong. And who really can forget the past? What else is there to know?
Robert M. PirsigScience probes; it does not prove. Imagine Newton's reaction to an objector of his law of gravity who argued that he could not establish a universal law because he had not observed every falling apple, much less proved the law of gravity - there might, after all, be an apple that levitates! Why should a group of simple, stable compounds of carbon, hydrogen, oxygen and nitrogen struggle for billions of years to organize themselves into a professor of chemistry?
