Different philosophical frameworks including utilitarian, rights-based, and capability approaches reach different conclusions about animal welfare; understanding these frameworks deepens welfare advocacy.
Philosophical frameworks for animal welfare ethics provide foundations for advocacy and policy positions that go beyond pragmatic welfare science. Singer's utilitarian approach generates the conclusion that animal suffering counts equally to human suffering of similar intensity, providing a strong argument for dramatic reduction of animal use in food production and research. Regan's rights approach argues that animals have inherent value that cannot be traded off against human interests, providing a foundation for abolitionist positions. Nussbaum's capability approach focuses on what species-specific flourishing requires, aligning closely with welfare science. Understanding these frameworks deepens the ability to engage with different audiences and policy contexts using philosophically coherent arguments.
