It would be interesting to apply the techniques of the Islamic science of hadith to studying go proverbs. This would weed out KGS musings, and leave many of the best proverbs at the forefront. It would also create a niche for KGS musings, and show some KGS musings to derive from actual proverbs. I myself am not a Muslim for many good reasons, but I have studied Islamic civilization and lived in the middle east, and I think stealing methodologies from the science of hadith, for the creation of a sort of go-playing hadith would benefit the go playing community. I am throwing this idea out there for people to play around with. Read the relevant wikipedia article if interested.
Interesting idea. We certainly need to clean up this grab bag of real proverbs and musings. And I agree, the way to do that is by examining validity. But that seems to me where the similarity ends. I don't see a need for the depth of hadith: We don't have 100,000s of proverbs, and it hardly matters who related a proverb, as long as it works. Whether it works can be see with direct sources (recorded games) and deliberation (analysis of problems). Or am I missing something?
All proverbs fail in some positions, i.e. there are no universally valid proverbs. For example, one of the best-known proverbs is the one about empty triangles but there is even a special Japanese word, guzumi, for an empty triangle that is a good move.
