some people would call it "metalanguage", Lacan says there's no metalanguage, as it is all language
if you want to have a theory, you need to make reductions from natural language (abstractions), so that you have a formal system
it is like a second language
like using English to talk about Portuguese
bad example, because E. and P. are both natural languages
all metalanguages have flaws, the thing is, it is possible to know where the rabbit hole is
the limitations of the system
but it is possible to create ways to manipulate problems that seemed impossible to solve
like the creation of imaginary numbers to deal with square root of -1
Lacan does this in psychoanalysis, it is amazing
to symbolize an impossibility, in his case, he uses "a", the famous "object a"
he creates speech formulas with this
