6. Agnosticism in Science and Anthroposophy

I do not hesitate to say that if you are steeped in today's scientific spirit and have not first done intimate, honest historical studies, you will inevitably misunderstand a scientific work from a period such as the 13th and 14th centuries AD, for the simple reason that even in those days – and the further back we go in human development, the more this is the case – man not only brought mathematics into the external world, but also a whole wealth of inner experiences in which he believed just as we believe in our mathematics. Thus we address nature quite differently today when we chemists speak of sulfur, phosphorus or salt than when people of that time spoke of sulfur or salt. If we apply today's concepts, we do not in the least touch the meaning that was then in a book, even one meant to be scientific, because at that time more and something other than the mathematical or the similar to mathematics was carried into the results of observation of the external world. Man brought a whole wealth of inner experience – qualitatively and not merely quantitatively – into the outside world.
