Our thoughts and actions are very much unified and guided by our worldviews. Consciously knowing that our worldview is chosen arbitrarily will very likely induce a sense of disorientation. In a postmodern world, not just one reality is being constructed and offered to us. It is a cable or carnivalesque culture. Even religious traditions, which used to be authoritatively imposed, now have to be marketed.
Religious traditions become consumer commodities.
In both modern and premodern times, religion involved beliefs about what is real. Today religion is not seen as a set of beliefs about what is real and what is not. Rather, religion is seen as a preference, a choice. We believe in what we like. Intellect gives over to will and spiritual experience.
