Albert EinsteinWhen I'm judging a theory, I ask myself whether, if I were God, I would have arranged the world in such a way.
Albert EinsteinHowever we select from nature a complex [of phenomena] using the criterion of simplicity, in no case will its theoretical treatment turn out to be forever appropriate (sufficient).... I do not doubt that the day will come when [general relativity], too, will have to yield to another one, for reasons which at present we do not yet surmise. I believe that this process of deepening theory has no limits.
