Lecture V

Indeed, there were many things that one did not dare! If a judgment were pronounced it was only half given, as in the case of du Bois-Reymond [a leading German physiologist at the turn of the nineteenth century] who delivered a speech about the boundaries to the knowledge of Nature. He said that supernaturalism could not be mentioned in connection with natural science, for supernaturalism was faith and not knowledge. Science stops short at the supernatural—and nothing further was said by him on the subject. If mentioned, people got excited and said that this was no longer science; consistency was not a characteristic of the century then ending.
