What it’s about: The follow-up to Three Body Problem details humanity’s centuries-long stand against the invading Trisolarians. In an attempt to overcome the ubiquitous surveillance of the sophons, humanity vests its hopes in the plans of Wallfacers – individuals tasked with coming up with plans to save humanity that are only known to themselves. Luo Ji, a mediocre astronomer, is mysteriously granted the position of Wallfacer, but he has within him the seeds of a truth that will be the key to defeat the Trisolarian threat.
- The Dark Forest has a rare conceptual brilliance – it bandies around concepts with the aplomb of a latter-day Asimov. Indeed, with this book, I really do think that the series has cemented its place as a kind of latter-day Foundation series with its centuries-sweeping cosmic story, its breathtaking ideas about the impact of unimaginable change on society, and its preoccupation with immutable laws that govern the behaviour of sapients.
- Of course, Dark Forest also shares some of the criticisms of Asimov – spare prose and dialogue, functional characterisation, and a kind of conceptual parsimony to its depictions of society that doesn’t take into account the gnarly complexities of the real world.
- In fact, The Dark Forest also has a very anime feel to it – it has a lot of similar tropes to high-concept anime science fiction such as Psycho Pass – as well as an unbridled and almost delirious creativity in concept and nomenclature. Wallfacers, sophons, droplets – these could have come right out of anime. Not to mention that protagonist Luo Ji spends a fair amount of his time being preoccupied by hallucinations of an imaginary girlfriend (literally), which other characters take to mean that he has the rare ability of a true literateur. This kind of thing is unfortunately also the preserve of a surprising proportion of anime.
- The use of hibernation allows the book to skip centuries’ worth of time, which allows Liu to advance epochs to hundreds of years in the future. Humanity has developed a magnificent space fleet and settled many worlds in the solar system, and feel confident to face the Trisolarian threat. It is an optimistic picture, but unfortunately one that has to be curtailed in a bit of a hackneyed fashion when Liu breaks out the classic “underestimating your enemy trope”, in which humanity’s entire fleet is destroyed by a single ship of the Trisolarians due to their overconfidence. This allows Liu to execute the “saved by the seat of your pants” dramatic trope by allowing Luo Ji to come up with the solution to save humanity from the jaws of defeat at the last moment, at the end of the book.
- Though I don’t quite begrudge that use of dramatic tension – Luo Ji’s secret is in many ways the conceptual centrepiece and the origin of the book’s name. In a twisted but brilliant union of the concepts of MAD and the Fermi Paradox, Liu paints a picture of a universe teeming with hidden life, where the ironclad rules of Dark Forest theory mean that any species that reveals its location in the galaxy is immediately eliminated as a potential threat due to the uncertainty of its intentions when resolved over vast gulfs in spacetime. Thus, species hide themselves, qua Fermi’s question is answered. When faced with the spectre of ultimate and easy destruction by infinitely more powerful species, that serves as a powerful deterrent – try to harm me, and I will reveal our location to the cosmos, resulting in annihilation of both species. A brilliantly elegant solution to resolve the story that, to be sure, has its own flaws, but its sheer parsimonious simplicity is very compelling, and provides plenty of food for thought coupled with a visceral sense of wonder-horror at the grandiose, dark, threatening web that is the wider galaxy.
Verdict: Brimming with ideas, elegantly executed, and hiding a truly incredible science fictional twist at its end, The Dark Forest is probably my favorite novel in the series.
I give this: 4.5 out of 5 droplets
