A new nonfiction book, THE LIGHT EATERS, by Zoe Schlanger, delves deeply into the potential of plant intelligence. According to the blurb, she explores the abilities of plants "to communicate, recognize their kin and behave socially, hear sounds, morph their bodies to blend into their surroundings, store useful memories that inform their life cycle, and trick animals into behaving to their benefit, to name just a few remarkable talents." Here are two articles about THE LIGHT EATERS and the amazing ways plants interact with their environment:
The New Science of Plant Intelligence
This topic raises the question of what "intelligence" means. I've always thought of it as a product of consciousness. Yet most people accept that advanced computer programs are in some sense intelligent without being conscious. If plants have intelligence, that quality must not necessarily require consciousness. And what does "memory" mean when applied to a creature without a brain? Do plants engage in "behavior," or should that word be restricted to animals? Botanical research has come a long way since THE SECRET LIFE OF PLANTS (1973) popularized the claim that they enjoy music and benefit from being talked to.
The second article linked above meditates on these questions and related philosophical issues. We human beings have an innate compulsion to "order the universe into comprehensible categories" and a tendency to "rank ourselves at the top." About plant communication, the author of this essay advances the astonishing proposition, "It also changes the notion of what a mind is. We have taken it to be the product of a brain attached to a nervous system, but perhaps a mind is a complex, self-organizing system networked across the entire organism. Perhaps the whole plant is a mind."
Schlanger defines intelligence as "the ability to learn from one’s surroundings and make decisions that best support one’s life,” a criterion plants fulfill. However, the temptation to anthropomorphize them should be resisted. For one thing, as many SF authors have highlighted, they must surely "think" on a different time scale from us. Rather than trying to see plants as human-like, we should appreciate their very alienness.
