There is no contradiction in the statement that we have to trust our senses, and that we have to develop them to make them trustworthy. For, 'nature speaks upwards to the known senses of man, downwards to unknown senses of his'. Goethe's path was aimed at wakening faculties, both perceptual and conceptual, which lay dormant in himself. His experience showed him that 'every process in nature, rightly observed, wakens in us a new organ of cognition'. Right observation, in this respect, consisted in a form of contemplating nature which he called a 're-creating (creating in the wake) of an ever-creative nature' (Nachschaffen einer immer schaffenden Natur).
