 Memory (Block (1996)). “[Y]ou remember the color of the sky on your birthday last year, the year before that, ten years before that, and so on, and your long-term memory gives you good reason to think that the phenomenal character of the experience has not changed…. Of course, memory can go wrong, but why should we suppose that it must go wrong here?” (pp. 43–44, italics and boldface original). The idea is that memory acts as a check on the sensory qualities, and can be used to support the claim that the qualities have remained unchanged despite the wholesale shift in representational contents.
