Do Animals Have Moral Rights That Humans Must Respect?

“The Cambridge Declaration on Consciousness, signed by prominent neuroscientists in 2012, affirmed that mammals, birds, and fish possess the neurological structures associated with conscious experience. Consciousness is the basis on which we extend moral consideration to other humans; the scientific case for extending it to other sentient beings is now stronger than the case against.”

“We already acknowledge that animal suffering matters: every US state has anti-cruelty laws covering dogs, cats, and horses. Factory farming applies conditions to pigs and chickens — gestation crates, battery cages, debeaking — that would be federal felonies under the Animal Welfare Act if applied to the animals that Act covers. The inconsistency is economic, not principled.”

“Rights, in the philosophical tradition from which the concept derives, imply duties. An entity with rights must also bear responsibilities toward others in the moral community. Animals cannot honor contracts, exercise restraint, or be held accountable for their actions toward other beings. Granting rights without reciprocal obligations is not rights theory; it is welfare maximization with a more politically powerful label.”

“The animal rights argument, taken to its logical conclusion, applies to insects, which are sentient by most empirical definitions used by the pro side. There are an estimated 10 quintillion insects on Earth; farming, construction, and walking outside kills millions per person per year. The argument either draws an arbitrary line or proves too much.”
