Lecture III
[^3]: Non-Euclidian geometry is a prime example of “the self-contained inner ability to think.” C. Friedrich Gauss (1777–1855) discovered first that one can think more than only a geometric system. Because nobody understood this, he decided not to publish his results and to withdraw from the fruitless quarrel. Independently of Gauss in 1828 N.I. Lobatschewskij and in 1829 J. Boljai first published their solutions to the same problem. Rudolf Steiner often spoke about the meaning of this achievement, as in Wege und Ziele des geistigen Menschen in the lecture “ Der Heutige Stand der Philosophie und Wissenschaft,” (Dornach, Switzerland: Rudolf Steiner Verlag, 1973; GA Bibl. Nr. 125). See also: Georg Unger, Physic am Scheidewege (Dornach: 1948), pages 19–28, and Vom Bielden Physikalischer Begriffe, Vol. 3 (Stuttgart: 1967), pages 31–32 and 193–194.
