Written 1886 (CW 2)
Rudolf Steiner's first book, published in 1886 when he was twenty-five years old, represented for him a true beginning in the search for deeper knowledge. In his preface to the 1923 edition, he wrote:
"As I look at it again today, it also appears to me to be the epistemological justification for everything I said and published later. It speaks of the essential being of knowing activity that opens the way from the sense-perceptible world into the spiritual one."The Science of Knowing is a translation from German of Grundlinien einer Erkenntnistheorie der Goetheschen Weltanschauung mit besonderer R cksicht auf Schiller (CW 2).
