The reason there weren’t words for the experience, however, is that the population didn’t *need* words for it. It wasn’t something they had to think about, so it wasn’t spoken about. This is the main difference between newspeak and natural language. If there is something people need to talk about (or think about), words are generated. If someone tries to communicate a new concept poorly, they will do what they need to, and eventually natural language will expand to fit the concept.
This is how we get language change from “gravity (heavy, weighty)” to “gravity (attraction between two masses)” – the latter meaning wasn’t quite the same, but it was a good start. That, plus formulae and further explanation created the language for a new concept.

If we couldn’t think about things we didn’t have words for, how would scientific progress occur? How would we write fantasy fiction or science fiction? Star Trek is the best evidence against linguistic determinism I can think of: tricorders and tachyons would both be impossible without thought about non-existent things. Someone had to think them up (and who hasn’t wanted a handheld box that could tell you everything you needed to know).
