15. Spiritual Science, Natural Science and Technology
Take geology, for example. I will pick out one example. It is better to talk about specific questions than to use general phrases. I understand completely and have followed this method myself: if, from what is happening around us today in the formations of rock, in the deposits of rivers and water and so on, we examine the geological layers that lie on top of each other and then calculate – even if it is not always a real calculation, but only something approximate, if you calculate how long these respective rock layers have existed, then you get the known figures. And then, as you all know, we arrive at the beginning of the earth's development, where the earth - as is hypothetically assumed - formed out of something, out of a kind of primeval nebula or something similar. I do not need to go into this in more detail. You are familiar with all this.
