Adrian Tchaikovsky – Children of Ruin
A big part of the process of modernity is widening one’s circle of concern. People have always looked out for themselves and their family. As trade grew, people’s circle widened from the tribe to include one’s trading partners, whether in a farm-and-village dynamic or including long distance traders. As the scale widened, people had to be more accepting of people who dressed differently, spoke different languages, and worshipped different gods. The process is not over. In the last 70 years or so, the circle of concern has grown to address racism, homophobia, transgender rights, and more. The proper size of one’s circle of concern is at the heart of today’s debates over issues such as LGBT rights, trade, and immigration. Animal rights activists are even trying to expand the circle of concern to other species.
What does the circle of concern have to do with a science fiction novel? A lot. In Children of Time, the first book in this series, a botched attempt at seeding an alien planet with Earth life leads to an advanced civilization of spiders and ants, instead of the intended apes (a literal barrel of monkeys burns up while entering the atmosphere). The nanovirus-enhanced intelligent spiders and humans eventually become allies, widening their circles of concern to include two very different sentient species.
This book is the sequel; I do not know if further volumes are planned in the series. It introduces a race of nanovirus-enhanced octopi as well as an alien life form that is something like a slime mold. Where the first volume was evolution-themed, this volume is about psychology and consciousness. It is more interested in exploring and understanding how different species think, feel, and communicate. It as though Tchaikovsky is expanding Adam Smith’s circle of concern as broadly as he possibly can, and seeing what happens.
Tchaikovsky’s spiders communicate through vibration and touch, and are unable to hear human speech. Both spiders and humans come up with all kinds of translators and ways to understand each other, and though their friendships are sincere, some differences are too vast for them to comprehend. Also of interest is the spiders’ own gender disparity, in which males are discriminated against and discounted as inferior, mirroring our own species’ issues. The spiders have even been making progress in recent generations, with male spiders advancing to prominent scientific research positions, though workplace politics are touchy.
The stars of this book are nanovirus enhanced octopi, who ancient humans seeded on one of two habitable planets in a different star system than the spider planet from the first book. Tchakivsky researched the subject, and the octopi in his book are impulsive, emotional, factional, and quick to change their minds as their emotions explore different sides of an issue. Not being able to use speech like humans or vibrations like spiders, octopi instead communicate by changing colors. Different feelings are automatically expressed in different colorations, which they are unable to hide. They almost literally wear their emotions on their sleeve, and their intellectual deliberations are plainly visible.
Also putting in a turn is an alien life form with a collective consciousness, kind of like an intelligent slime mold or a bacteria with a long collective memory and the ability to interface with and control other organisms. This lets Tchaikovsky explore a whole other form of consciousness, of which we don’t have any examples on Earth.
The plot throws these very different consciousnesses together and lets them try to sort out who is on who’s side, how to overcome communication barriers, and try to come to some kind of understanding. The extent to which they can succeed requires a circle of concern rather greater than most people on Earth have today.
