>It's probably because of the Age of Enlightenment in the west that did a thorough self evaluation over a few centuries.
I'm not sure what a "thorough self evaluation" would actually mean. I don't think that's even remotely feasible, given the immense scope of the subject matter. What has happened is that certain elements within western civilization have focused their efforts on criticizing western civilization, some in good faith and some not, and the rest of western civilization has allowed them to do so. That is the part that is rare, just like suicide, and for the same reason.
