Years ago I read a book called
The True Believer - discussing the personality type of those who are soldiers of Christ or Allah or Marxism or Fascism - belief systems that welcome a totality of commitment. An oldie but a goodie - recommended.
Nevertheless, I'm always a little nervous about psychologists naming passionate belief systems as syndromes that can and should be 'cured'. It reminds me of 'curing' homosexuality. Many Psychologists are not above the social prejudices of their culture.
Every religion started as cult. A cult is a shared system of belief. Because a small number of people believe something doesn't automatically preclude it from being a healthy belief system. To the extent that people view the word 'cult' as pejorative, it is not then necessarily an accurate label.
I believe the world is always becoming more terrible and more wonderful. Because man's technological capacity is always advancing, man is capable of using that technology in terrible and wonderful ways. With human population growing rapidly, technology is being wielded by more and more people, which further amplifies its effects. Technology renders a society more complex and interconnected than ever, and the rate of change is accelerating.
We all want something constant in a world where the rate of change is accelerating. The faster the rate of change, the more desperate is the need for a constant. We want a belief system that makes sense of it all, that explains it all.
It can be a frightening world. As Bob Dylan wrote "May you have a strong foundation when the winds of changes shift." Humanity is is a constant process of destroying the familiar to create something new, and then trembles at the result. I believe that this is what Hindus called the God Shiva. Mankind constantly re-invents different Myths to explain this process. Old religions will die out, new ones will take their place.
