This study aims to clarify the structure of Hegel's epistemology as a foundation of Steiner's educational thought. This study is composed of four chapters as follows: 'The epistemological struggle of Steiner: Before Hegel'; 'Hegel as a Philosopher who accepts 'Goethe's Worldview' and understands the significance of the Greek Proverb, "Know thyself"; 'Understanding Steiner on Hegel's Theory'; and 'The Difference between Steiner's and Hegel's thought'. The first two of these chapters will be printed in this issue, while the second two will be printed in the next issue. As a result of this study, two points concerning Steiner's view of Hegel's reputation become apparent. The first point is that Hegel adopts dynamic metamorphosis theory as Goethe does. The second point is that Hegel finds the perspective of 'metamorphosis' in 'thinking' as self-recognition―'know thyself'―which Goethe could not accept. Steiner appreciates Hegel as 'a Philosopher who has Goethe's worldview' and expresses 'the view of Metamorphosis' in his idea. This proverb of 'know thyself' (γνῶθι seaυtόν (gnothi seauton) refers to the inscription carved into the temple of Delphi. Steiner thinks that this ancient, divine message encourages us to disclose the mystery of the world through 'thinking'. In the next issue, the study considers and clarifies the aspects of Hegel's philosophy that Steiner considers to have philosophically systematized the proverb "know thyself'.
