Rudolf Joseph Lorenz Steiner (German: [ˈʃtaɪnɐ]; 27 or 25 February 1861 – 30 March 1925) was an Austrian New Age guru, philosopher, occultist, social reformer, architect, esotericist, and claimed clairvoyant and speaker with the dead. Steiner gained initial recognition at the end of the nineteenth century as a literary critic and published works including The Philosophy of Freedom. At the beginning of the twentieth century he founded an esoteric spiritual movement, anthroposophy, with roots in German idealist philosophy and theosophy. His teachings are influenced by (Christian) Gnosticism or neognosticism. Many of his ideas are pseudoscientific. He was also prone to pseudohistory.
In the first, more philosophically oriented phase of this movement, Steiner attempted to find a synthesis between science and spirituality by developing what he termed "spiritual science", in which he sought to apply the clarity of thinking characteristic of Western philosophy to spiritual questions, intending to differentiate his approach from what he considered to be vaguer approaches to mysticism. In a second phase, beginning around 1907, he began working collaboratively in a variety of artistic media, including drama, dance and architecture, culminating in the building of the Goetheanum, a cultural centre to house all the arts. In the third phase of his work, beginning after World War I, Steiner worked on various ostensibly applied projects, including Waldorf education, biodynamic agriculture, and anthroposophical medicine.
Steiner advocated what has been described as ethical individualism, to which he later brought a more explicitly spiritual approach. He based his epistemology on Johann Wolfgang von Goethe's world view in which "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." A consistent thread that runs through his work is the goal of demonstrating that there are no limits to human knowledge.
