> Am I being irrational here? Not so much irrational as not particular enough; this line of reasoning doesn't really work. The thing is ... at any one instant, the amount of memory you are able to recall / visualize / etc is very small, and if your mind is occupied by that thought, you won't have any thoughts about the present simultaneously. It is only the apparent continuity of time that seems to link these things. So when you say "thinking about all the other things in my memory", well, you can't experience all the things that are supposedly in your memory. You can only experience one small part of that at any time. If there is only one time, then the other stuff does not exist, you just have confidence that it exists for some reason.
