IT is pretty well established that animals are capable of suffering; we’ve come a long way since Descartes famously compared them to nonfeeling machines put on earth to serve man. (Rousseau later countered this, saying that animals shared “some measure” of human nature and should partake of “natural right.”) No matter where you stand on this spectrum, you probably agree that it’s a noble goal to reduce the level of the suffering of animals raised for meat in industrial conditions.
