 Third, one might contend that Kant’s Refutation demonstrates that the reference in question must be (relatively) permanent, and that there is nothing in the Berkeleyan spatial realm that satisfies this requirement. However, to this one might respond that the reference by which I determine the temporal order of my past experiences need not be permanent in a way that cannot be satisfied by Berkeleyan spatial objects. If in the corner of my field of consciousness featured distinct momentary flashes, every second, indicating the date and time to the second, I would be able to determine the temporal order of my past experiences by their means (cf., van Cleve, reported in Dicker 2004: 207).
