Quote by Robert M. Pirsig

“Science 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?”
