On thought police, self reinforcing perceptions, beliefs and the like - not just in the afterlife, but right here, even on this forum. I'm borrowing from a bit I wrote recently to a good friend.

Debate/discussion surely becomes utterly sterile if everybody is herded towards agreement of a single view or set of beliefs - it becomes dogma.

That's even when it appears like a competitive if disciplined academic debate - because that sort of engagement is usually driven largely by a suppressed ego urge to control, or to belong to the controlling group.

It's important to try not to get too attached too specific beliefs or views, at least not anyway to the point where we feel we have to defend them too agressively.

To have lots of views at all sorts of levels in flow together is potentially far more constructive - even quite simple views often provide new insights, and the resulting mix must surely illustrate any topic far more comprehensively, and promote far more self enquiry and progress than a single view can.

Accepted dogma creates a culture where people no longer feel free to express a view, even tentatively.

A more open environment leaves everybody free to speak, and if they are taking responsibility for themselves, and not just looking for a winning team to join they can draw from it what's relevant to self and situation. (we each have quite different needs)

That's not to say there shouldn't be debate on topics, or that we shouldn't say so if we disagree with a point. But there's a point beyond which its possible to become too aggressive, one that shuts things down. 

We should perhaps bear in mind too that as above that there's strength in a diversity of views.

Put another way - there's very few spiritual truths that can be expressed without many intersecting views to delineate the territory and its inevitable nuances and possibilities. Openness is so important...
