Barthes: “It would be good to imagine a new linguistic science that would no longer study the origin of words, or etymology, or even their diffusion, or lexicology, but the progress of their solidification, their densification throughout historical discourse; this science would doubtless be subversive, manifesting much more than the historical origin of truth: its rhetorical, languaging nature.”

Did anyone ever develop this science? I want to study it and apply it.
