The present article is focusing on influence of the thought presented by Julian Ochorowicz on forming philosophical and medical conception of Władysław Szumowski. To be sure, Ochorowicz belonged to one of the most vivid and famous personages of Warsaw Positivism. A contriver, visionary, spiritualist and votary of mediumism rose to speak about many problems that, among others, concerned medicine. Undoubtedly, he was a precursor of a modern clinical psychology in Poland and the first scholar, who perceived the hypnosis to be an important diagnostic and therapeutic method. His stipulation saying that psychology should be an obligatory subject for students of medicine lately has been appreciated properly. Nevertheless, his eccentricity, self-confidence in his skills, and at the same time the fact he did not graduate from medical studies brought about a severe criticism, and even ostracism in medical circles. As he was accused of dilettantism and swindle, only a few were ready to stand up for him and, among others, Władysław Szumowski – a doctor, philosopher and historian, a devotee of the holistic outlook upon medicine. In the field of medicine Szumowski was tending to join physical and material aspects with all what dodges traditional science and is its important fulfillment. The outlooks of Ochorowicz, and particularly the ideas concerning the psychology's presence in medicine, turned out to be interesting for Szumowski, and influenced his theoretical considerations.
