Well, I don't want to get involved myself in another power struggle. Sometimes I feel quite an urge to do so
In and of itself, the introduction of historical criticism into Theravada can be quite a healthy process.
However, it happens naturally, and many people do the excellent work in this area without much ado.
There were too many holy wars already, where historical interpretations were used as a weapon. Every side in these wars had a proper and right version of history.
Actually, there's no need for "proper and right" history. Let there be many shades and colors, with multiple interpretations.
Why should some perspectives be considered as 'unreasoned' or 'uncritical'?
May everyone study what he likes, and do it at his best. No one knows exactly what happened thousands years ago, and that's normal.
What's really lacking is the high-quality open dialogue. Dialogue where every statement can be brought to light and studied from multiple perspectives. It requires quite a courage to bring own beliefs under question from other people.
For example, here in Ukraine and Russia we conduct well-moderated Skype conferences. People share their knowledge, give reasons for the views, and answer questions.
Internet provides all the necessary means for the transparency of views and open dialogue.
I hope that such openness will become a standard.
Such a perspective will be reasoned - in the sense that everyone will give clear reasons for opinions. And it will be critical - in the sense that other people's reasoned views will be included in the dialogue.
And everyone who studies such dialogue will be able to obtain his own unique well-reasoned conclusions.
