In 1790, a year before Galvani's monograph, Concerning the Forces of Electricity, appeared, Goethe published his Metamorphosis of Plants, which represents the first step towards the practical overcoming of the limitations of the onlooker-consciousness in science. Goethe's paper was not destined to raise such a storm as soon followed Galvani's publication. And yet the fruit of Goethe's endeavours is not less significant than Galvani's discovery, for the progress of mankind. For in Goethe's achievement lay the seed of that form of knowing which man requires, if in the age of the electrification of civilization he is to remain master of his existence.
