In 1915, 100 years ago this month, Sigmund Freud published a paper in which he described what he had discovered in his psychoanalytic patients: that there is an aspect of the human psyche of which individuals are typically profoundly unaware, namely the unconscious. His explorations set in motion a broad and fascinating path of investigation that gripped other key 20th century figures such as Carl Jung, and with which we are still engaged today. In this Science Set Free podcast, Rupert Sheldrake and Mark Vernon discuss this dynamic aspect of human life and how the unconscious relates to ideas from the soul to morphic fields.
