I take issue with the assertion that there was a period where all people could agree on a world view. Most of the 20th century was defined by sharp disagreement between world views and all of their constituent parts. Perhaps if you limit the scope to all citizens of a nation then the statement would be more truthful but there are large disagreements there as well.
One thing I liked about reading "The Three Body Problem" was the unique (to Westerners) worldview it portrayed, and the difficulties of academic science in China under the Mao regime - very different from the worldview in post WWII America.
