Can you tell a book by its title? Does the title of Marcel Proust’s In Search of Lost Time say what it is about? Is it about “losing time”: Amnesia?

“In Search of Lost Time” is a very peculiar title, because people usually refer to things that they don’t remember as things that they have forgotten.

“Losing time” is something else entirely.

People speak of “losing time” when their lack of memory goes beyond normal, ordinary forgetting. It is a way of saying that they have amnesia, because there is something that they should be able to remember, but they don’t.

Is “In Search of Lost Time” about someone who is trying to overcome amnesia? And if so, what is the medical or psychiatric cause of his amnesia?
