G. T. Fechner (1848): Plants as sentient living beings
Plant Signaling & Behavior February 18, 2026 Giulia Parovel
Gustav Fechner's 1848 arguments for plant sentience, long dismissed as mystical, are grounded in empirical observation and inductive reasoning. He proposes that a plant's complete immersion in its environment—earth, water, air, and light—makes every environmental change accessible to its experience. Because plants are sessile, survival demands total presence, so while they lack animal-like memory and anticipation, their immediate sensory experience may be more intense than human perception. Fechner's framework offers biologists, psychologists, and neuroscientists a way to reconceptualize intelligence, suggesting sentience is an intrinsic property of life, not merely a product of neural complexity.
