I. The Goal of Knowledge 1 This chapter was moved to 'Appendix II' by Rudolf Steiner for the second edition of 1918 in a slightly revised form.

The reader will be led at first into somewhat abstract regions, where thought must draw sharp outlines if it is to reach secure conclusions. But he will also be led out of these arid concepts into concrete life. I am fully convinced that one cannot do without soaring into the ethereal realm of abstraction, if one's experience is to penetrate life in all directions. He who is limited to the pleasures of the senses misses the sweetest enjoyments of life. The Oriental sages make their disciples live for years a life of resignation and asceticism before they impart to them their own wisdom. The Western world no longer demands pious exercises and ascetic practices as a preparation for science, but it does require a sincere willingness to withdraw oneself awhile from the immediate impressions of life, and to betake oneself into the realm of pure thought.
