It could be called a study of seeing. | | Given one way of seeing, certain models and conclusions can be | drawn. But change the seeing and the models cease to hold. And | then change it again. And again. | | We have a couple of methods for messing with that. A whole | seeing-cultivation program. | | Lots of good mystery there. | oment wrote: | ecco? | | who is we? | | your comment hist.
