There are some interesting questions of approach here.
As someone whose day job is science, my impression is that the Secular Buddhist approach (as in Ted’s article) shows little appreciation of other possible knowledge systems.
Personally, I don’t find looking for scientific evidence for Dhamma ideas particularly interesting. Science is a particular knowledge system that is really useful for understanding atoms and stars, and developing technology, but that doesn’t necessarily make it the right tool for awakening.
I think it’s interesting that Dave points out the similarity to other faith based systems. Is there a problem with that? Should Dhamma be defined by a Scientific World View?
