I believe some of what is described here was called “philosophical nonsense” by Rudolph Carnap:
“According to Carnap, philosophical propositions are statements about the language of science; they aren’t true or false, but merely consist of definitions and conventions about the use of certain concepts”
“nonsense results from the use of language outside the limits of a language-game or linguistic framework; the task of the critic of philosophy is to point out when and how philosophers have transgressed the limits of their linguistic system”
