Thanks for making that clarification, which is important. You interpret my meaning correctly, it is not that the value is moving up along the y-axis in the graph of the function y=2x+7, but that for increasing x's, there are increasing y's. In the same sense, we can interpret that as one looks at ascending time-slices, you will see accumulating memories, etc. Edgar's assertion that we "wouldn't feel like we are moving through time" unless time "really moves", contradicts computationalism, which his theory supposedly assumes. (Actually, I see no way at all how successively creating and and then deleting successive slices in time even could explain our sensation of moving through time.)
