The word "livestock" first appeared in English in the 1500s — not as an insult, but as an accounting term.

Dead stock was equipment. Live stock was capital that breathes.

Five hundred years later, that word is still shaping what animals are legally allowed to be, how they are housed, and what we are permitted not to ask about them.

This episode traces the word from its origins through the industrialization of food systems, the legal invisibility of farm animals, the behavioral science documenting their cognitive and emotional lives, and the legal and technological shifts now beginning to challenge a five-century-old premise.

Language doesn't just describe the world. It builds it.
