This month marks the centenary of Sigmund Freud's seminal 1915 paper on the unconscious. In this episode of Science Set Free, Rupert Sheldrake and myself discuss Freud's understanding of this dynamic, hidden part of the human psyche. We look at the different ideas of Carl Jung, and also ask how the unconscious links to perceptions of the soul and morphic fields.

The discussion is available as a podcast or on iTunes.
