        This article explores the theory of mediumship proposed by Julian Ochorowicz (1850–1917), a Polish positivist thinker and scientist. Ochorowicz’s objective was to establish mediumship as a scientific discipline distinct from spiritualism, which he criticised for its ideological and dogmatic nature. He advanced the theory that a multitude of purportedly paranormal phenomena could be elucidated through unconscious psychological and physiological mechanisms, including ideoplasty and involuntary muscle movements. However, he also hypothesised the existence of a ‘dynamic atmosphere’ or an etheric body – an invisible, subtle part of the human organism capable of acting beyond the physical body. The concept under discussion aimed to establish a connection between matter and spirit, imagination and physical reality. Notwithstanding the opposition mounted by the academic establishment and the subsequent decline of the ether theory following the advent of relativity, Ochorowicz’s theories foreshadowed aspects of subsequent advancements in quantum theory, thus constituting an intriguing endeavour to comprehend the unexplained through the lens of scientific methodology.
