We stress that these always are merely images, model-like soothes of our struggling and searching, which moreover should take their point of departure in the above mentioned processes. What a truly hopeless thought! In this sense all scientific knowledge is rather a soothing of the urge to know, rather than genuine representations of reality. The building blocks of the World then appear as psychogeneous cognitive slag, when the fire of the urge to know has smothered. The practical value-criterium of such images, which, of course, should be poor in contradictions in themselves as well as against one another, is the personal and possibly also collective satisfaction with them. The idea of absolute (natural) science is very beautiful indeed. Until now it is only relative.
