Finally, there is a question whether there is a presumed one life world as a ground of various societies and cultures, or do such societies and cultures comprise distinct and, at times, incompatible life worlds. If there were one life world, and we were completely immersed in it, then we would not recognize our immersion. If there were more than one, then we would either belong to one or another and thus would interpret the other in terms of our own and hence fail to recognize the distinction between them. If we can access both, then we cannot belong to either and must have an awareness of both and their differences. This awareness is taken for granted in all such comparative studies of cultures and civilizations.
