But now, I note as I type this that my Mac computer has adjusted all by itself, and the time it gives in its little corner time-place is correct. We set our watches ahead a couple of hours, so we go to bed when it gets dark and get up when it gets light and are not unduly inconvenienced by the absence of electric lights. We fool ouselves, advertently, so we don't have to chnge our normal eating and sleeping times. Jane notes that last year the kids refused to go along with this simple but effective trick. So there are hierarchies of reality within the world of mental constructs.
Some memes are more real than others.
This idea of differing levels of reality within the world of the human mind would seem to have possibilities. Maybe we should water this seedling a bit, move it into the sun, and see how it grows.
