D-503, a true believer in the authoritarian future he finds himself in, has his faith in the structures of society shaken by love. <-- a quick and dirty recap of We, D-503's diary.
The world-building in these older dystopias is very different from today's, but you can draw a straight line from We (the first novel banned by Soviet censors in 1921) to a TV show I've only seen advertised in recent years about a dome over civilization, and of course everything in between. (The dome in We is described only as something between their society and what lies outside, and it's there so people aren't soiled by nature, not because people have ruined nature.)
D-503 sets out in his diary to show an unknown reader how glorious his mathematically logical "unfreedom" is. How happiness can only be found with the help of state doctrine, one that says freedom will lead to complete havoc and therefore ruin the beautiful order in their society, where even sex is organized by the state - lest the mess of personal, private love ruin everything.
It's easy to see how this could be attractive in the abstract, and how absurdly comical it is too. Can a perfect, ordered collective actually make someone happy? Can there be a perfectly ordered collective? The knowing me says of course not, but people always want to order things, to make them less complicated and more logical. Humanity is messy, and D-503 learns this when he falls in unsanctioned lust and love. Love is anarchy, both in the book and when I really think about it (which makes my brain hurt.) Love is the most illogical, but biologically imperative, thing humans do.
Zamyatin doesn't rail against the state as much as I expected. Instead he reveals through increasingly confused and unsure diary entries what it means to be an individual, one who exists not just as a cog in a wheel, but one who exists also for his own purposes, with his own ideals.
This is a deep work that can be seen on a variety of levels, but I found it most gratifying as a rumination on how complication and chaos are vital to living a full, satisfying life, despite how much we'd all like it to be otherwise with our lists and rules. To truly live, must we allow for some disorder, some illogic, some freedom?
