Rights-based animal ethics argues that animals have inherent value that cannot be overridden by utility calculations. Understanding Regan's framework broadens the philosophical foundation for animal protection.
Animal rights philosophy provides a more demanding but arguably more principled foundation than utilitarian welfare ethics. Where utilitarians can in principle justify animal use if the aggregate welfare balance is positive, rights theorists argue that animals with inherent value cannot be treated as mere resources regardless of welfare considerations. This distinction has practical implications: rights advocates tend to reject welfare improvements in animal use as insufficient and work toward abolition rather than reform. The two frameworks coexist uneasily in the animal advocacy movement, but both contribute to challenging anthropocentric assumptions and expanding ethical consideration for animals.
