Lawrence LeShan worked as a clinical psychologist and researcher, conducted extensive research in the field of parapsychology. In the book The Medium, the Mystic, and the Physicist, he connected “mystical” thoughts/beliefs and advanced these ideas further. He elucidated psychic abilities such as telepathy, clairvoyance, precognition, as well as enhancing such abilities internally. LeShan presents scientific and experimental practices following procedures to demonstrate valid results. Overall, he believed that mystical thinking could be explained using physics (quantum theory) and science, pioneering advances in parapsychology and psychotherapy. LeShan presents unique ideas that may not be suitable for most, even the approach taken: synthesizing "extra-ordinary" abilities into a psychology-based experimental (empirical) method to structure a rigorous procedure that incorporates the physiological abilities to be strengthened, e.g. example type 1 and type 2 healing, in order to produce valid results. Not only that, LeShan rigorously attempts to make his procedures repeatable, an absolutely necessary step in the scientific method. An experiment or study must be repeatable by following exactly the same methods to achieve similar results. Then demonstrate a hypothesis to be confirmed or rejected based on valid results. As for LeShan, I believe it was difficult to show results in the early stage of a new field (parapsychology), since there is little to no research conducted that could serve as an a priori in the experiment. This motivated LeShan to present consistent procedures following his own scientific approaches to obtain results for the formed hypotheses. LeShan was able to remove doubts and let the results speak for themselves, through the repeatability of the methods to pre...... middle of the paper ......rall, I liked the approach of LeShan was careful in his experimentation to present unbiased data. He developed ideas and procedures that had positive results. Not only that, it seems that LeShan talks about humanistic concepts also presented by James Hillman and Carl Jung, such as love, care, absoluteness, unity, mysticism, nature and God. Once again, comparing Jung, Hillman and LeShan, similar themes are present, the unconscious, the psyche and the self. Furthermore, an individual must be able to develop internally through techniques or have a powerful inner core composed of love, to enable healing or enhance biological abilities. It is indicative that a level of absoluteness is reached when one achieves oneness: with Nature and God. In conclusion, this development of the inner core fills and enhances an individual, thus allowing him to function in the Universe.
