It's been a few years since I read it. I recall enjoying watching Thoreau pull apart any idea of state morality and legitimacy. If you want a modern-day account of the same to read to your son may I suggest Larken Rose's, "The Most Dangerous Superstition"? It's a bit longer but 100% 🔥
Some weeks ago I was reading Thoreau's "On the Duty of Civil Disobedience" aloud at bed-time to my son, who of course does not understand it but appreciates the sound of the words all the same, when I discovered that its famous title was in fact not the original! The original title was significantly more radical: "Resistance to Civil Government."
It's quite short, and I would encourage everyone here to read (or re-read) it. It is still tremendously relevant. Re-reading it with the original (un-sanitized) title in mind, it lands even harder.
These days, Thoreau would probably get his door kicked in.
