The religious issue in American society has been developing for several decades. It is not as simple as the old Protestant-Catholic competition nor does it reflect the former Christian-Jew diversity.
[The New Age ... has been a smorgasbord of religious experiences derived from any religious tradition willing to advocate its beliefs and whatever experiences could be packaged for sale to American consumers. Thus astrology, numerology, flying saucers with heavenly “space brothers,” past-life regressions, a variety of martial arts techniques, various brands of shamanism, and modern versions of witchcraft fill the empty hours of affluent fringe groups who reject Christianity but want to have some hold on religious experiences.]
The religious situation today eloquently reflects the American psyche - we create our own reality and we are absolutely free to do so. This condition, however, suggests that there is no reality and that we live in a completely intellectual world where the free choice of the individual determines the values and emotional content of experiences. We are at ground zero religiously with little possibility of a revelation to enable us to move on.
[...]
While we would like our personal preferences to be realized, if we have any sanity, we must admit that the world outside our perspective has a bit of substance to it and must certainly be constructed on certain principles through which history and nature are related. It is therefore our task to examine with a great deal of seriousness the possible relationships that these two ideas have and the probable configuration that a new understanding of history and nature and time and space would give us.
