Weltanschauung
Etymology
German, from "Welt," world, and "Anschauung," view, perception, or intuition. It entered philosophy to name the entire interpretive framework behind a person’s opinions, rather than any one opinion within it.
noun · /VELT-ahn-show-oong/
A comprehensive worldview — the entire framework through which a person or culture interprets reality.
What it names
Not any single belief but the whole lens that quietly shapes all of one’s beliefs.
Example
The two economists agreed on the data but clashed on everything else, because their whole Weltanschauung differed.
Related idea
Shares its "Welt" with weltschmerz, world-weariness; where a zeitgeist is the mood of an age, a Weltanschauung is the map of reality a mind or age holds.
