3. Natural Science and Anthroposophy

It is evident from the fact that we see how the most diverse hypotheses have been put forward - hypotheses about light, about the phenomena of electricity, about gravity, and so on. We see how these hypotheses are always replaced by others. And anyone who does not want to completely accept the point of view that we have “come so gloriously far” today must, from these feelings that he may have about this building of hypotheses, say: the hypotheses that have been developed recently will in turn be replaced by others. We are, so to speak, in the middle of replacing the old light hypothesis with another, taken from electrical phenomena. And we have to say to ourselves: we are entering an area where we form hypotheses based on the laws of nature that the mind can gain from external observation and through external experimentation in relation to the sensory world. We come into a region where this mind, so to speak, encounters a fluid, a something that cannot evoke in us the feeling that we can actually approach a being with these mental constructs that we hypothetically form and that, if they are to have a value, can only have this value if they point to something real, to something that exists.
