At this point in our discussion it is necessary to introduce another leading concept of Goethean nature-observation, which was for him - as it will be for us - of particular significance for carrying over the Goethean method of research from the organic into the inorganic realm of nature. This is the concept of the ur-phenomenon (Urphänomen). In this latter realm, nature no longer brings forth related phenomena in the ordering proper to them; hence we are obliged to acquire the capacity of penetrating to this ordering by means of our own realistically trained observation and thought.
