Rudolf Steiner (25 February 1861 – 30 March 1925), born in Donji Kraljevec, Croatia, was an Austrian philosopher, literary scholar, educator, artist, playwright, social thinker, and esotericist. He was the founder of Anthroposophy, Waldorf education, biodynamic agriculture, anthroposophical medicine, and the new artistic form of Eurythmy.
Steiner advocated a form of ethical individualism, to which he later brought a more explicitly spiritual component. He derived his epistemology from Johann Wolfgang Goethe's world view, where “Thinking… is no more and no less an organ of perception than the eye or ear. Just as the eye perceives colours and the ear sounds, so thinking perceives ideas.”
