Although Schiller had listened up to this point 'with great interest and definite understanding', he shook his head as Goethe finished, and said - Kantian that he was at that time: 'That is no experience, that is an idea.' These words were very disappointing to Goethe. At once his old antipathy towards Schiller rose up, an antipathy caused by much in Schiller's public utterances which he had found distasteful. Once again he felt that Schiller and he were 'spiritual antipodes, removed from each other by more than an earth diameter'. However, Goethe restrained his rising annoyance, and answered Schiller in a tranquil but determined manner: 'I am glad to have ideas without knowing it, and to see them with my very eyes.' Although at this meeting Goethe and Schiller came to no real agreement, the personal relationship formed through it did not break off; both had become aware of the value of each to the other. For Goethe his first meeting with Schiller had the significant result of showing him that 'thinking about thought' could be fruitful. For Schiller this significance consisted in his having met in Goethe a human intellect which, simply by its existing properties, invalidated Kant's philosophy. For him Goethe's mind became an object of empirical study on which he based the beginnings of a new philosophy free from onlooker-restrictions. An essay, written by Goethe about the same time as the one just quoted, shows how he came to think at a later date about the raising of human perception into the realm of ideas. In this essay, entitled Discovery of an Excellent Predecessor,9 Goethe comments on certain views of the botanist, K. F. Wolff, regarding the relationships between the different plant organs, which seemed to be similar to his own, and at which Wolff had arrived in his own way.
