unless the belief is supported by current authorities (science, your church, etc.) I would like to make a quick case for saying this is counterproductive. 1) I think it is fine to explore beliefs that are not CONTRADICTED by current authorities. In fact, within science at least, this is part of advancement. Let's take meditation. Go back 100 years and some Americans probably came in contact with some Eastern ideas about meditation. They got the impression or were told that meditating might alleviate what we might call stress or otherwise improve the quality of life. This idea may not have cohered especially well with current science, but I do not think it direcly contradicted any. So the curious or intuitively drawn explored meditation and some found some positive effects. Decades later Western Science found that, in fact, meditation does seem to promote 'well being' in significant numbers of practitioners, even those trying simply as study subjects. It was not wrong of those people to explore a belief or practice that was not supported by current science. Now a stronger claim on my part..... 2) I think it is fine to explore beliefs (or act as if one believes) contradict current science. Because in some cases this contradiction is only apparent. People noticing effects that seemed to support Lamarkian evolutionary ideas could have not investigated further, not wanting to be accused of being silly. But then the effects of epigenetics - processes that can seem Lamarkist, but are not - might not have been found out so quickly. I am sure there are other examples where scientists explored a hypothesis that seemed to contradict some current science. There have even been very uneasy periods when their research seemed to contradict current ideas - the particle wave issue, some quantum effects - and integration was a struggle. Later apparent contradictions could be placed in context. When it comes to individuals and beliefs, I often get the impression that when presented with a new idea - or starting to consider an insight one made oneself - the person SHOULD check immediately with authority - church, current scientific theory. If the idea/practice seems to contradict - or be based on ideas that contradict (or seem to!) current science or the church on is in time to cast it away. Likewise if the idea is not supported. The idea of exploring the ideas and seeing what happens is seen as, by definition somehow, irrational. Even though church founders - the Buddha, Jesus..... - and scientists explored these kinds of potentially contradicted things themselves, often what is now considered by authorities to be our great benefit. And how much time is one allowed to explore something before one must be considered irrational?
