I have some problems in reading whether Popper was a proponent or a critic of what's called "historicism". Historicism means belief systems that believe in some kind of logic in historical and societal development that can be predicted by studying history and one's own time.
Historicism (also known as Historism) holds that there is an organic succession of developments, and that local conditions and peculiarities influence the results in a decisive way.
Now, for a modern scientific mind this sounds very irrational. How exactly could such predictions ever be possible? Then were proponents of historicism mad or religious? But particularly, did Popper "belong" to this school or was he criticizing it?
