Chapter 2: How Science Changes Its Mind

How Science Changes Its Mind traces the philosophical roots of our disconnect from nature, exploring how Indigenous kinship models and the observations of Theophrastus—who viewed plants as autonomous, desiring beings—were overshadowed by Aristotle’s scala naturae, which solidified a hierarchy placing plants at the bottom as mere instruments for human use. The narrative details the long shadow of Cartesian mechanism that justified vivisection and denied animal consciousness for centuries, until recent cognitive revolutions, such as the Cambridge Declaration on Consciousness, forced a reevaluation of animal minds. A central theme is the application of Thomas Kuhn’s theory of scientific revolutions to the current crisis in botany, where the "normal science" of viewing plants as passive objects is being challenged by the controversial field of plant neurobiology and the revival of Charles Darwin’s "root-brain" hypothesis, which suggests root tips act as command centers. The text weaves these high-level debates with the on-the-ground reality of extinction in Kaua‘i, where botanist Steve Perlman fights to save "naive" island plants that evolved without defenses, illustrating the fragility of these complex organisms. Finally, the chapter proposes that we may be on the verge of a paradigm shift that recognizes distributed intelligence—similar to that of an octopus or a neural network—as a valid form of consciousness, potentially reshaping our ethical and scientific relationship with the botanical world.
