noun: World view; philosophy of life; a framework through which to interpret the world.
From German Weltanschauung (world view), from Welt (world) + Anschauung (perception).
When we bring in a word from another language, sometimes we borrow it and at other times make a loan translation. The word weltanschauung appears so useful that English has borrowed the original form and also made a loan translation: world view.
"Gwyneth Paltrow summed up her weltanschauung thus: 'My life is good because I am not passive about it.'"
