15. Spiritual Science, Natural Science and Technology

People can, if they study the methods of knowledge acquisition in detail, as the great physiologist Du Bois-Reymond did, arrive at the point of view that Du Bois-Reymond expressed in his lecture “On the Limits of Natural Knowledge” at the famous natural science conference in Leipzig in the 1870s and also repeated in his lecture on “The Seven World Riddles”. I will only briefly point out that at that time Du Bois-Reymond spoke of the fact that with the application of what has been called “unified thinking” here, one comes to develop the so-called Laplacian mind, that is, to develop such thinking about matter as is possible when one seeks to grasp the course of the planets of a solar system using astronomical-mathematical methods.
