Interference (Semiosis Duology #2) , by Sue Burke


Compared to the the first installment of the series, this book isn't as good. There are enough vestiges from the original story to keep tale familiar right from the start. The author abandons the previous book's generational storytelling format where each  chapter is told from the perspectives of descendants to a shorter time-frame but told from different characters point of view.  Almost all of the characters are new, mostly unlikeable and harboring their own agenda. While the overall arc of the main plot was loosely interesting enough, I feel the the story of the Corals were introduced too close to the end of the book. A little more foreshadowing the of dangers brought by the Corals could have fleshed out the main antagonist.  Overall, though enjoyable enough, it feels as though this book is a "setup" for another installment in this series as a lot of effort and time is put into fleshing out the newly introduced characters yet leave a lot of the results of their actions driven by their oft-not compatible motivations unresolved.


I give it 4.5 out of 5 stars

Sue Burke’s new science fiction novel Interference is the sequel to her previous book Semiosis. That book introduced us to Pax, a superhabitable Earth-like planet some fifty-six light years away. Human colonizers, fleeing an ecologically and politically ravaged Earth, arrive on Pax; they must learn to get along with the native life forms. These include, most notably, intelligent plants. All the plant species on the planet are sentient to varying degrees; they are often engaged in Darwinian struggles against one another as well as against the animals who feed on them. There are also a number of language-capable animal species too, including the predatory eagles and the scavenging bats. (The colonists give names reminiscent of Earth species to all the life forms they discover, even though their biochemical makeup and descent are quite different). Pax also has a population of large arthropod-like beings known as the Glassmakers; intellectually and culturally, they are at least the equals of Homo sapiens, though their manners and outlooks are unsurprisingly quite different. In Semiosis, the human community learns, over the course of several generations and about a hundred years, that in order to survive they must give up their colonialist/pioneering/conquering mentality, and instead negotiate ongoing relationships with the other species. By the end of the novel, a stable community of human beings and Glassmakers has been established, with both species in effect playing the role of “service animals” for Stevland, the intelligent bamboo species that dominates the portion of the planet on which they live.

Burke draws on recent scientific research that has discovered that, already here on Earth, plants are sentient in the sense that they actively sense and monitor their environment, they are able to learn and remember, they make decisions among possible alternatives, and overall they respond flexibly to the situations in which they find themselves. Plant neurobiology is a real scientific subfield. For more on this, see the recent books by Daniel Chamovitz and by Monica Gagliano. Only animals have cells specialized as neurons, but non-specialized plant cells exhibit the same physiological bases for thought — electrochemical reactions and transmissions from cell to cell — as animal neurons do. Of course, Burke’s intelligent plants on Pax are extrapolated far beyond anything that actually exists on Earth. But such further specialization, on the basis of already-existing biochemical processes, is not wildly implausible. Intelligence in varying degrees is a useful adaptation, evidenced to some extent in all living organisms on Earth, and there is no reason why it could not develop further. On Pax, plants have cells specialized in similar ways to animal neurons {Another science fiction novel that includes speculation on neural cells added to plant architecture is Joan Slonczewski’s The Highest Frontier}.

You definitely need to read Semiosis first in order to make sense of Interference. But given that, the sequel at least equals the previous book, and adds layers of richness to Burke’s world-building. Interference picks up the story about a hundred years after the end of Semiosis. The human/Glassmaker/bamboo community is largely doing well. Life on Pax is not quite a utopia, but it arguably allows for a greater degree of flourishing than most of the actual social formations we are familiar with here on Earrh. There are all sorts of minor injusticies, power differentials, and petty disputes and jealousies. And there is a lot of work to be done: many advanced technologies have been lost, and metals are generally not available. Nonetheless, the small society on Pax, organized around one single village, offers a lot of room for personal idiosyncrasies. Many things are done collectively, and resources are shared on a mostly equal basis. Everyone has access to food and shelter. People accrue obligations to one another, but there is no money. Glassmaker society is matriarchal and somewhat hierarchical; among the human inhabitants there seems to be gender equality. Humans and Glassmakers together make decisions on a more or less democratic basis, though there is no doubt that Stevland, the intelligent bamboo, has ultimate authority.

But Stevland is not a dictator; it understands that its own well-being is entirely intertwined with that of the two other sentient species, as well as with a wide variety of other plant and animal life with which it remains in communication. The politics of Pax rests upon the biological conditions of commensalism, mutualism, and symbiosis. One of the best things about both novels is the way that Burke imagines such relations arising out of Darwinian competition. Burke’s vision stands in opposition to selfish gene theory, but it is in general accord with more recent theories about the evolution of cooperation, multi-level selection, and ecological webs of multispecies dependencies. Burke does not skimp on the horrors of predation and parasitism; some of the competition among species described in both volumes is violent to the point of extermination. But the novels also insist on the ways that mutual dependencies are also a crucial part of evolution; cooperation itself evolves, and complex forms of life could never come to exist without it. Most importantly, perhaps — at least from a human point of view — is the fact that the multispecies community on Pax maintains a more or less steady state, in terms of energy, ecology, and economics. It does not strive to endlessly expand in the manner of all too many human societies on Earth, ranging from ancient and early modern despotic regimes all the way to contemporary capitalism.

The ground for all this was already established in Semiosis; but Interference pushes things a lot further. The second book has a wider scope than the first. Interference starts on Earth, and we witness a near future involving massive genocide followed by the establishment of an ecofascist regime. This helps us appreciate, by contrast, the positive aspects of life on Pax — despite its dangers, and its lower levels of technology and material well-being. At the start of the novel, Earth has lost contact with Pax; a spaceship is sent there on a scientific mission, to find out what happened as well as to check on the animal and plant life. This allows Burke to avoid the danger that is often attributed to utopian fiction: a portrait of a more or less stable and satisfying social situation can lead to a boring, conflict-free narrative. Instead, we get massive cultural and political conflict, already among the human beings on the spaceship, even before they arrive; and all the more so, once they have arrived, between them and the humans on Pax, not to mention all the other species.

I will avoid spoilers at least to the extent of not recounting any of these conflicts in detail. I will restrict myself to several observations. The book extends the range of sentient species further than had already been done in the first volume. Imperatives of both violent conflict, and grudging or active cooperation, together with instances of both understanding and misunderstanding, continue to ramify in Interference. Burke does not extend her vision of sentient diversity to the extent of radical incommunicability, i.e. the existence of intelligences so different from one another that they are unable to communicate at all. But she does try to imagine how sentient arthropod (Glassmaker) intelligence might in fact be quite different from ours, and plant intelligence even more so. This is highlighted in Interference by the way that each chapter of the novel has a different narrator: we get Earth humans, Pax humans, Glassmakers, and plants. The ongoing events are described from vastly varying perspectives. Interestingly, it is the human narrators who come out the worst: they range from badly misunderstanding what they experience, to seriously delusional, to outright sociopathic. The Earth humans come out as far worse than the Pax humans, though the latter also show serious limitations. The chapter narrated by a Glassmaker is somewhat more understanding and sensible than any of the human ones; and the chapter narrated by Stevland is the most rational, observant, emotionally balanced, and self-aware of all. We also get, from Stevland’s perspective, a powerful sense both of the plant’s stable rootedness and rhizomatic proliferation, and of the constriction it feels from being unable to really travel.

In short, Interference gives us an absorbing and exciting story, but it also asks us to think about how things might be otherwise than what we take for granted, both for better and for worse. In particular, it thinks about emotion, intelligence, and the problems of living with others in both a biological and a sociological register. It neither reduces social processes to biology, nor pretends that biology is irrelevant to our own species being (or to those of presumptive other intelligent beings). It extends Darwinian perspectives to the social and intellectual realm — and it does this in ways that are opposed to, and offer a useful counterpoint to, the nastily reductive fictions of’ so-called ‘evolutionary psychology.’ All in all, Interference, like its predecessor, is science fiction at its best.
