No one knows. Repeated experiments have failed to locate where memories are stored in the brain, casting doubt on the conventional assumption that memories are stored as material traces. In this episode of the Sheldrake-Vernon Dialogues, Rupert Sheldrake and Mark Vernon discuss various kinds of memory, from episodic memory to habits. They consider how memory is linked to emotion and place, drawing on insights from Aristotle to AN Whitehead. Rupert’s own work has led to the theory of morphic fields, within which all self-organising systems dwell. They also ask about Indian ideas of memory and how that is related to ideas about reincarnation and the possibility that everything that exists lives, in some way, in the memory of God.
