War I. A lodge called Mystica Aeterna within the Masonic Order of Memphis and Mizraim, which Steiner led from 1906 until around 1914. Steiner added to the Masonic rite a number of Rosicrucian references. The School of Spiritual Science of the Anthroposophical Society, founded in 1923 as a further development of his earlier Esoteric School. This was originally constituted with a general section and seven specialized sections for education, literature, performing arts, natural sciences, medicine, visual arts, and astronomy. Steiner gave members of the School the first Lesson for guidance into the esoteric work in February 1924. Though Steiner intended to develop three "classes" of this school, only the first of these was developed in his lifetime (and continues today). An authentic text of the written records on which the teaching of the First Class was based was published in 1992. Philosophical ideas Goethean science In his commentaries on Goethe's scientific works, written between 1884 and 1897, Steiner presented Goethe's approach to science as essentially phenomenological in nature, rather than theory or model-based.

He postulated that Goethe had sought, but been unable to fully find, the further transformation in scientific thinking necessary to properly interpret and understand the animal kingdom. Steiner emphasized the role of evolutionary thinking in Goethe's discovery of the intermaxillary bone in human beings; Goethe expected human anatomy to be an evolutionary transformation of animal anatomy. Steiner defended Goethe's qualitative description of color as arising synthetically from the polarity of light and darkness, in contrast to Newton's particle-based and analytic conception. A variety of authors have termed Goethean science pseudoscience. According to Dan Dugan, Steiner was a champion of the following pseudoscientific claims: Goethe's Theory of Colours; "he called relativity 'brilliant nonsense'"; "he taught that the motions of the planets were caused by the relationships of the spiritual beings that inhabited them"; vitalism; doubting germ theory; non-standard approach to physiological systems, including claiming that the heart is not a pump. Knowledge and freedom Steiner approached the philosophical questions of knowledge and freedom in two stages. In his dissertation, published
