Do Plants Feel Pain?

Abstract

Abstract Many people are attracted to the idea that plants experience phenomenal conscious states like pain, sensory awareness, or emotions like fear. If true, this would have wide-ranging moral implications for human behavior, including land development, farming, vegetarianism, and more. Determining whether plants have minds relies on the work of both empirical disciplines and philosophy. Epistemology should settle the standards for evidence of other minds, and science should inform our judgment about whether any plants meet those standards. We argue that evidence for other minds comes either from testimony, behavior, anatomy/physiology, or phylogeny. However, none of these provide evidence that plants have conscious mental states. Therefore, we conclude that there is no evidence that plants have minds in the sense relevant for morality.
