Ever since John Locke, philosophers have wondered about memory and its connection to the self. Locke believed that a continuity of consciousness and memory establish a “self” over time. Now psychology is weighing in with new research suggesting that the relationship between memory and the self is even more complicated than that. But what’s the connection between memory and the self? Can the self be explained strictly in terms of memory? Or might the self be something over and above what memory suggests?
