8. What is Mortal in Man?

As spiritual science develops as a fruit of human spiritual striving, something like the Goethean theory of colours will also be recognized along with spiritual science itself. Then people will understand why another spirit, who also felt the impulse of the eternal spiritual in his soul, who, motivated by the same impulse, also wanted to comprehend the outer world, why this spirit stood up for the theory of colours, and indeed for something else — Hegel, Hegel was also one of those who were deeply connected with the sustaining power of the German spirit, which has already been described here yesterday. With all the power of eloquence that was his, he opposed the belittling of his fellow countryman Kepler, the great Kepler, who is known to anyone who has even slightly looked into a physics book as the one who found the so-called Kepler's laws. Hegel showed that these laws already contain what Newton had merely formulated in mathematical formulas. The world has otherwise noticed this only a little. Hegel has shown: Newton puts mathematical letters where Kepler has expressed his laws; he only changes a little the formulas. Newton has done nothing but expressed in mathematical terms and formulas the Kepler laws. But Hegel was concerned with the reality and not with the form of expression.
