 : I read some and think it's an article worthy to be shown. If it doesn't work out, consider to create a related article (a person, an institution teaching it ...) and make a hook mentioning the philosophy. It will get not as much attention as the bolded article, but a lot, promised. I did that for many Bach cantatas which I couldn't expand five times: create a singer's article, then say that the singer performed the cantata. In 2015, I made them GA instead ;)
