Goethe started from the conviction that our senses as well as our intellect are gifts of nature, and that, if at any given moment they prove incapable through their collaboration of solving a riddle of nature, we must ask her to help us to develop this collaboration adequately. Thus there was no question for him of any restriction of sense-perception in order to bring the latter in line with the existing power of the intellect, but rather to learn to make an ever fuller use of the senses and to bring our intellect into line with what they tell. ‘The senses do not deceive, but the judgment deceives’, is one of his basic utterances concerning their respective roles in our quest for knowledge and understanding. As to the senses themselves, he was sure that ‘the human being is adequately equipped for all true earthly requirements if he trusts his senses, and so develops them as to make them worthy of trust’.
