'In the range of phenomena all had equal value in Bacon's eyes. For although he himself always points out that one should collect the particulars only to select from them and to arrange them, in order finally to attain to Universals, yet too much privilege is granted to the single facts; and before it becomes possible to attain to simplification and conclusion by means of induction (the very way he recommends), life vanishes and forces get exhausted. He who cannot realize that one instance is often worth a thousand, bearing all within itself; he who proves unable to comprehend and esteem what we called ur-phenomena, will never be in a position to advance anything, either to his own or to others' joy and profit.' What Goethe says here calls for the following comparison. We can say that nature seen through Bacon's eyes appears as if painted on a two-dimensional surface, so that all its facts are seen alongside each other at exactly the same distance from the observer. Goethe, on the other hand, ascribed to the human spirit the power of seeing the phenomenal world in all its three-dimensional multiplicity; that is, of seeing it in perspective and distinguishing between foreground and background.4 Things in the foreground he called ur-phenomena. Here the idea creatively determining the relevant field of facts comes to its purest expression. The sole task of the investigator of nature, he considered, was to seek for the ur-phenomena and to bring all other phenomena into relation with them; and in the fulfilment of this task he saw the means of fully satisfying the human mind's need to theorize. He expressed this in the words, 'Every fact is itself already theory'. In Goethe's meteorological studies we have a lucid example of how he sought and found the relevant ur-phenomenon. It is the breathing-process of the earth as shown by the variations of barometric pressure. * Once again we find Thomas Reid, along his line of intuitively guided observation, coming quite close to Goethe where he deals with the question of the apprehension of natural law by the human mind. He, too, was an opponent of the method of 'explaining' phenomena by means of abstract theories spun out of sheer thinking, and more than once in his writings he inveighs against it in his downright, humorous way.5
