“If spiritual science is to do the same for spirit that natural science has done for nature, it must investigate quite differently from the latter. It must find ways and means of penetrating into the sphere of the spiritual, a domain which cannot be perceived with outer physical senses nor apprehended with the intellect which is bound to the brain.”

Austrian philosopher and esotericist

Rudolf Steiner was an Austrian philosopher, social reformer, architect, and esotericist. He became known at the end of the nineteenth century as a literary critic, and later for founding anthroposophy, an esoteric spiritual movement rooted in German idealist philosophy and theosophy. He also wrote works including The Philosophy of Freedom. His teachings drew on Christian Gnosticism or neognosticism, and he was described as a claimed clairvoyant who said he could speak with the dead. Many of his ideas are regarded as pseudoscientific, and he was also associated with pseudohistory.
