There's a lot of linguistic cross-definition conflict around words like "abstract" and "reductionism" in different discursive traditions.

For example some circles take "abstract" to mostly mean "lossy" or "imprecisely defined" whereas others take it to mean "any claim of consistency/universalization/generalization from particulars"

Similarly "reductionism" is variantly taken as "radical analysis completely describing root dynamics" and "a simplifying account that erases everything of import".
