What do we owe to non-human animals?

Moral status: Standing that gives others direct moral reasons to consider a being's good.

Sentience: The capacity for felt experiences such as pleasure, pain or distress.

Speciesism: Unjustified preference for interests simply because they belong to one's own species.

Animal rights: Protected claims that constrain how animals may be used, regardless of total benefit.

Equal consideration: Giving comparable interests comparable moral weight without demanding identical treatment.

Jeremy Bentham and Peter Singer: The utilitarian tradition places sentience and interests at the centre rather than rationality or species. Equal consideration does not mean identical treatment; it means that like interests, including avoiding suffering, cannot be discounted merely because the being belongs to another species. Tom Regan: Regan argues that beings who are subjects of a life possess inherent value rather than value only as containers of welfare. Rights constrain the ways they may be used, even for beneficial consequences. The approach challenges practices that treat individual animals simply as resources. Martha Nussbaum: Nussbaum's capabilities approach asks what different creatures require to flourish in characteristic forms of life. Justice concerns opportunities for bodily health, movement, affiliation, play and other capabilities, not only pleasure or pain. The account must avoid imposing a human picture of flourishing on other species.

Her relational ecological perspective examines dependency, power and the backgrounding of non-human life. Moral thought should not reduce animals either to copies of humans or to passive resources.

A conclusion needs support from the stated reasons. Here, an extra linking premise is required before the consequence follows.

Whether a thinker is likeable does not establish whether their argument is sound. The reasons themselves must be assessed.
