15. Spiritual Science, Natural Science and Technology

What does that actually mean? It means establishing the inner discipline within oneself to be able to look, just as one otherwise looks at external objects, at what one finally has in one's soul when one arrives at such a borderline concept; I could name many others to you besides those I have just mentioned. Then, when one tries to concentrate the whole range of the soul on such concepts, abstracting from all other experiences, one makes an inward discovery. And this inner discovery is a shattering one. It shows us that from a certain point in life, in our inner life, our concepts become something that grows in our soul through itself, that is different after such inner meditative work than it is when we take it only as the result of external observation. Just as we observe in the growing child how certain organs, which first appear more undifferentiated, become more differentiated, how we perceive how organs grow, so in such meditative devotion to the results of scientific experience we feel how an inner growth of the soul takes place. And then comes the shocking realization that it is not through speculation, not through speculative philosophy that one goes beyond what is called the limit of natural knowledge, but through direct experience, that is, by transforming what one has gained through thinking into inner experience of beholding.
