What do animals know about death — and what can it teach us? Chimpanzees care for the sick and mourn their fallen peers. Orcas carry deceased calves for weeks, as if unable to come to terms with the loss. Elephants cover the corpses of their kin with branches and soil, performing a primitive funeral rite. And the opossum, when faced with danger, pretends to be dead: it falls into paralysis, lowers its body temperature, sticks its tongue out, and emits a deathly odor. Like Schrödinger's cat paradox, it is both alive and dead at the same time. As proven by the Spanish philosopher Susana Monso, animals do not just have a concept of death: their relationship with it is far more diverse and astonishing than we can imagine. "Schrödinger's Opossum" is a scientific detective story combining philosophical theory with the latest ethology and comparative psychology data, and observations of wild nature with reflections on existential questions.
