In "1984" George Orwell created a hypothetical language, called Newspeak, the deployment of which sought to eliminate rogue thoughts and emotions by incremental reduction in vocabulary.

From https://en.wikipedia.org/wiki/Newspeak:

The intellectual purpose of Newspeak is to express Ingsoc's worldview, and to attempt to make impossible all unorthodox (i.e. anti-Ingsoc) political thought. As constructed, the Newspeak vocabulary communicates the exact expression of sense and meaning that a member of the Party could wish to express, whilst excluding secondary denotations and connotations, eliminating the ways of indirect thinking that allow a word to have second and third meanings.

1984 is a fictional novel, but some of Orwell's ideas are playing out in today's reality - take "fake news" for example. I think the novel emphasises the connection between language and world view.
