The charitable interpretation is that shminux always implies in his points something similar to Eliezer's notions that you can't just step outside of your own perceptions to see the territory directly, but do have some mechanisms already in place that receive "new" information from somewhere which you have no control over, which is what (AFAICT) shminux calls "reality".

That's a little too charitable though, since that's effectively the view shminux is arguing against.
