For those of you who brought your copy of The Screwtape Letters, open to Chapter 1:
Jargon, not argument, is your best ally in keeping him from the Church. Don’t waste time trying to make him think that materialism [disbelief in the supernatural] is true! Make him think it is strong, or stark, or courageous — that it is the philosophy of the future.
This is relevant to discourse in general. Jargon means different things to different people; it is key to preventing meaningful communication. Social media is a gold mine of jargon, or a dilithium mine in the case of the original Star Trek. (Roddenberry hadn’t invented latinum yet.) Somebody will chastise the later spinoffs for being “woke” or “too political,” and someone else will claim that the show was that way from the start. Looking over the original series I find little in the way of allusion to real-world politics or ’60s liberalism, and nothing compatible with modern leftism.
