But although all our knowledge begins with experience, it does not follow that it arises from experience.[Wenn aber gleich alle unsere Erkenntnis mit der Erfahrung anhebt, so entspringt sie darum doch nicht eben alle aus der Erfahrung.]
All our knowledge is contained within this whole of possible experience.[In dem Ganzen aller möglichen Erfahrung liegen aber alle unsere Erkenntnisse.]
