What if the world you experience is not the world, but your world—one of countless complete, coherent realities constructed by every living thing?
In UMWELT, Nox Vale delivers a masterful exploration of Jakob von Uexkull's revolutionary concept of the Umwelt—the species-specific perceptual world that each organism inhabits as a fully realized, self-contained reality rather than a partial view of a shared universe. From the tick's three-element cosmos of butyric acid, warmth, and hair to the bee's ultraviolet meadows, the bat's echolocation landscape, and the human world of language and culture, Vale shows how organisms do not passively receive reality but actively construct it through their sensory-motor organization, functional circles, and inner worlds.
Blending rigorous analysis with accessible prose, this book traces the Umwelt concept from its biological origins through its profound implications in biosemiotics, phenomenology (Husserl, Heidegger, Merleau-Ponty), philosophy of mind (Nagel, Metzinger), cognitive science, autopoiesis, enactivism, and artificial intelligence. It examines how Umwelten shape ethics, politics, ecology, technology, art, and even dreams—revealing why destroying an organism's perceptual world is a deeper harm than we realize, and why AI's potential "Umwelt problem" challenges our assumptions about mind and meaning.
Rich with vivid examples—from migrating birds and fungal chemical networks to digital platforms and the microbiome—this is essential reading for anyone fascinated by consciousness, animal minds, the nature of reality, and humanity's place in a pluralistic universe of overlapping worlds. UMWELT does not merely explain a concept; it transforms how you see the meadow, the tick, the machine, and yourself.
