One popular cultural fantasy is that we are each the result of our physical environments.
Physical reality is perceived to be the only game in town.
We are regarded as being the sum of social forces stretching back into our childhoods. I am aware of this fantasy, but I don't believe in the ideas from which it arises and so subsequently don't experience it in my reality. Their beliefs have brought them to this point. Reality is reality, and fantasy is fantasy, and there is no direct intermixing of the two except in the area of sex. They employ the energy of their imaginations to create sexual images.
