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 spheres of life are many and for each there develop a special science. But life itself is one, and the more the sciences strive to penetrate deeply into their separate spheres, the more they withdraw themselves from the vision of the world as a living whole. There must be one supreme science which seeks in the separate sciences the elements for leading men back once more to the fullness of life. The scientific specialist seeks in his studies to gain a knowledge of the world and its workings. This book has a philosophical aim: science itself is to be infused with the life of an organic whole. The special sciences are stages on the way to this all-inclusive science. A similar relationship is found in the arts. The composer in his work employs the rules of the theory of composition. This latter is an accumulation of principles, knowledge of which is a necessary presupposition for composing. In the act of composing, the rules of theory become the servants of life, of reality. In exactly the same sense philosophy is an art. All genuine philosophers have been artists in concepts. Human ideas have been the medium of their art, and scientific method their artistic technique. Abstract thinking thus gains concrete individual life. Ideas turn into life forces. We have no longer merely a knowledge about things, but we have now made knowledge a real, self-determining organism. Our consciousness, alive and active, has risen beyond a mere passive reception of truths.
