You know there is a field of philosophy that study languages and meta-languages. It is now tightly tied to linguistic (maybe because of Noam Chomsky) but you have still logicians who publish in philosophical papers on this subject.
I agree. As I've just stated in another comment, it's hard to say something with substance about philosophy in general. There are just a lot of different fields with individual axioms and scientific methods.
That said, if these 'languages and meta-languages' fields would have found something viable (usage and usability), eg. a good tool to use, we would already use it.
I think they did, i've read an article about that with my previous job, when i was mostly working with EU and universities: they created a meta-language to convey ideas fast between scientists of different fields and talking different languages, but with a common culture.
I dont' have the paper but i found this [0] which might refer to the paper i read.
Not my cup of tea, but worth taking a look at.
