My earliest memory of Star Trek is from when I must have been in 2nd or 3rd grade, over at my next-door neighbor's house. The TV was on and there was a scene with a bulbous alien head with glowing eyes shrouded in mist saying something about trespass into its territory (I only learned much later that episode was entitled Spectre Of The Gun). My friend's mother said we shouldn't watch that cause it would scare us. Contrary to her statement, I was entranced. I didn't realize it at the time, but that episode (along with a copy of The Martian Chronicles on my dad's bookshelf) triggered a lifelong obsession with Star Trek, and SF in general.
Also without my explicit awareness, Star Trek was slowly and subtly affecting my thinking with progressive and humanistic values that were in conflict with the politically regressive and fundamentalist indoctrination of my parent's church. Star Trek has from its very beginnings been about a positive vision of humanity's potential to move beyond tribalistic fighting, and towards a society driven by more than just profit and conflict. Many people who claim to be fans of Star Trek can be heard grousing about what they call political correctness, or wokism, or whatever term they choose for dismissing anything they don't like, without actually taking time to understand the core arguments. These people are not actual fans of Star Trek. They haven't been paying attention.
This book was published nearly 40 years ago, and it is a perfect example of the kind of story those fake-fans would whine and cry about. This book is highly applicable to the current political climate in the US, with its central concerns of a society justifying the rampant detsruction of an ecosystem for the purpose of short term gains accompanied by the deliberate supression of scientific research and factual information. It is pretty much a direct analogue to the tobacco industry (in earlier times), and the fossil fuel industry (now), and the current continued denial of the reality of climate change. It's both amazing how much this book applies to what is going on now, and deeply depressing.
Besides the core story, there are numerous quotes that could apply to events of the recent 40 years:
"Oh, this isn't torture, commander. It's just an interrogation enhancement techniqe, useful for softening resistance."
"No government can last long if it neglects the physical realities of its world."
The writing is occasionally weak with some occasional cringe-inducing dialog, and the use of telepathy is probably my least favorite aspect of the Star Trek universe, but I accept it as part of the canon. Despite the flaws, I really quite enjoyed this book, more than I expected, which makes me think that maybe I should read more of the Star Trek novels, something I stopped doing back in my post-college years when I decided that franchise fiction was mostly not good.
