Anthroposophy and the Riddles of the Soul

Du Bois-Reymond believed – as he stated in his famous lecture “On the Limits of Natural Knowledge” – that the human being, as a conscious, waking being, is not transparent to his own knowledge, that this knowledge reaches certain limits when it comes to human consciousness. From the movements that the matter in our nervous system undergoes, we cannot understand — du Bois-Reymond said — how we feel: “I see red, I hear organ tones, I smell the scent of roses.” But du Bois-Reymond thought that ordinary natural science could be used to understand the sleeping person, in whom consciousness has dawned, and thus precisely that which, in his opinion, is unfathomable for ordinary natural knowledge. No! But through that in which natural science is great today, the sleeping person can be understood just as little as the plant. What pervades a being as life can only be seen in supersensible knowledge, in supersensible contemplation, as I have characterized it in my writings 'How to Know Higher Worlds' and 'Occult Science: An Outline' and in the two lectures already mentioned. What pervades man as a sleeping being, as invigoratingly as a plant, cannot be known through ordinary natural science. Here, man is only accessible as a physical being after he has died. And when he has died and lies before us as a corpse, we see how he begins to follow quite different laws from those he followed from birth or conception to death.
