Anthroposophy is a philosophy founded in the early 20th century by the esotericist Rudolf Steiner that postulates the existence of an objective, intellectually comprehensible spiritual world, accessible to human experience. Followers of anthroposophy aim to develop mental faculties of spiritual discovery through a mode of thought independent of sensory experience. They also aim to present their ideas in a manner verifiable by rational discourse and specifically seek precision and clarity in studying the spiritual world mirroring that is obtained by scientists investigating the physical world.
