Anthroposophy and the Riddle of the Soul

And du Bois-Reymond is actually completely right in this statement. There is a second limit for external natural science here, except that du Bois-Reymond's conviction is the one that must be overcome through anthroposophical research. Du Bois-Reymond believes that the limits of knowledge of nature are the limits of all science. Therefore, he says: If you want to penetrate into this realm of the spiritual and soul, you have to do it by means other than scientific ones. Because where supernaturalism begins, where, in other words, one enters the realm of the spiritual and soul, that is where science ends. This is precisely what anthroposophical research wants to defend before the world: that science does not have to be limited to the external-natural existence, that science can develop the means to penetrate into the spiritual-mental as well.
