QUOTE : In other words, your subjective feeling that time is flowing comes from the relations between these memories that you have right now. Imagine a thought experiment where a perfect clone of me is built asleep, complete with all my memories, and is only woken up long enough to perceive a single observer moment. He'd still feel that time flowed from a complex and interesting past, even though he got to experience only that one moment. This means that the subjective perceptions of duration and change are qualia, basic instantaneous perceptions just as redness, blueness or sweetness.
