Do animals have moral status?

How should we treat non-human animals — in food production, experimentation and cloning? Positions range from "animals exist for human use" to "animals have rights".

• Indirect duties — we owe duties about animals, not to them (Kant, Aquinas).
• Equal consideration — animal interests count (Singer).
• Animal rights — animals have inherent value (Regan).

Kant and Aquinas: indirect duties

• Kant: only rational beings are ends in themselves, so we have no direct duties to animals. But we should not be cruel, because cruelty to animals hardens us and makes us more likely to mistreat humans — an indirect duty.
• Aquinas: animals lack reason and so exist, in the natural order, for human use; cruelty is wrong mainly because of its effect on human character.
• Religious stewardship: many traditions balance human dominion with a duty of care for creation.

Whose indirect duty?

From sentience to equal consideration

Jeremy Bentham shifted the question: "The question is not, Can they reason? nor, Can they talk? but, Can they suffer?" Sentience, not rationality, brings moral relevance.

Peter Singer (Animal Liberation) develops this into the principle of equal consideration of interests: like interests must count equally, whoever has them. To discount an animal's suffering just because it is not human is speciesism — a prejudice like racism or sexism.

As a preference utilitarian, Singer opposes factory farming and much animal experimentation because of the vast suffering they cause.

Whose speciesism?

Regan: the rights view

Tom Regan (The Case for Animal Rights) takes a deontological, not utilitarian, line. Many animals are subjects-of-a-life — they have beliefs, desires, memory, a sense of the future and welfare that matters to them.

• Such beings have inherent value and therefore rights; they must never be treated merely as resources.
• Unlike Singer, Regan rejects the utilitarian trade-off: you cannot justify harming an animal just because it maximises overall good.

Difference to grasp: Singer weighs interests/consequences; Regan asserts rights grounded in inherent value.

Utilitarian or rights?

Food, experiments and cloning

• Food: factory farming causes immense suffering (Singer objects); rights theorists object to using animals as resources at all; others defend humane farming and stewardship.
• Experimentation: weighed by benefit to humans vs animal suffering; the "3 Rs" (replace, reduce, refine) seek a middle path; Regan opposes it in principle.
• Cloning: raises questions of animal welfare, "playing God", and unintended harms.

Weighing it up

• Is sentience the right basis for moral status, or does it prove too much (insects? plants?)?
• Does Singer's utilitarianism permit some animal use if benefits are large? Is that a strength or weakness?
• Can animals really be bearers of rights, or only of interests?
• How should religious ideas of dominion and stewardship shape practice?
