I think we may say that an event is ‘experienced’ when it sets up a habit. (Memory is one kind of habit.) Broadly speaking, habits are only set up in living organisms. A burnt poker does not fear the fire, however often it is made red-hot. On commonsense grounds, therefore, we shall say that ‘experience’ is not coextensive with the ‘stuff’ of the world. I do not myself see any valid reason for departing from common sense on this point.
