>>280372451Nietzsche's writing precedes that distinction, and philosophers on both sides reference him, but their interpretations differ to the point of being irreconcilable.
Roughly: the analytical side thinks his genealogical method means "Study dictionaries/historical references and document their differences. Compute the average using your favorite value-neutral method. Believe the result."
The continental side thinks it means "Dictionaries and historical documents are products of their times. Interpret them as such, reinterpret them according to our current values, and alert the reader to the fact that their current values may skew their interpretation. Nothing is value-neutral. Believe whatever feels good."
Obviously, both are wrong. The conclusion should be "Believe only what you can justify in terms of the belief systems of those opponents whose offspring has been allowed to believe the opposite of their beliefs without getting killed."
