Each of us lives in a world we have personally constructed, though usually we are not aware we have done so. Further, we have been able to construct our own personal world because we, in turn, have already been shaped by the culture into which we have been born.
Our personal world is largely drawn from the shared world which has given our culture its identity and coherence. This shared world is the result of a long and complex cultural evolution and has been collectively constructed by all our ancestors. There have been as many shared worlds as there have been human cultures.
