Lecture IX

Now, what makes it possible for us to have steam engines, which are by no means old? What is the basis of this possibility? You see, the year 1769—I shall now make an assertion that will seem extremely curious to everyone who thinks scientifically—when Watt first made the steam engine useful, was a year by no means far removed from Goethe's conception of the Faust. Although they lie far apart, perhaps we might discover in our reflections curious interrelationships between this steam engine and the conception of Goethe's Faust. But we must first survey in thought much that is connected with the introduction of the steam engine into human evolution. On what principle does the steam engine actually rest? It really rests on the possibility of creating space void of air, or occupied by little of it. The entire possibility of making steam engines rests on the creation and use of a vacuum. In ancient times men spoke of the horror vacui, the horror of a vacuum. Something objective was indicated thereby. It meant that space wants always to be filled with something; that something empty could really not be produced; that nature had a certain horror of a vacuum. First, the belief in the horror of a vacuum had to disappear. Secondly, the possibility had to be established that space containing little air or being almost void of air, could be created. Only then was it possible to consider the use of steam engines. The air had to be eliminated from certain spaces. It is not possible through a mechanical consideration to attain to a new cosmic, moral conception in contrast with the ancient cosmic and moral conception of the horror vacui. But what really happens when we create a space containing little or no air with the purpose of placing what is thus brought about in the service of human evolution?
