Rights-based advocates (e.g., Gary Francione) argue that welfare reforms are not only insufficient but actively harmful. By making animal exploitation appear more ‘humane,’ welfare measures dull public outrage and postpone abolition. For rights theorists, veganism is not a personal lifestyle choice but a moral imperative. The legal goal is to remove the property status of animals and grant them legal personhood (as has been achieved, to a limited degree, for great apes in Spain and for the chimpanzees in the Nonhuman Rights Project).

Principled consistency; aligns with abolition of other forms of oppression (slavery, child labour); provides a clear moral endpoint. Weaknesses: Politically radical and slow; disputes over which animals have rights (insects? bivalves?); does not offer a clear path for incremental change in the short term. 4. Applications: Three Contested Arenas 4.1 Factory Farming In industrial agriculture, the welfare/rights divide is stark. Welfare organisations (e.g., RSPCA’s Freedom Food, Humane Farm Animal Care) campaign for larger crates for sows, beak-trimming protocols for hens, and controlled atmosphere killing for poultry. Some successes include the EU ban on conventional battery cages (2012) and gestation crates in several US states.

For most of Western history, the answer was ‘nothing directly.’ Aristotle viewed animals as existing for human use; Descartes famously dismissed them as automata devoid of feeling; and Aquinas argued that cruelty to animals mattered only insofar as it led to cruelty to humans. However, from the 19th century onward, two distinct reform movements emerged. The first, , sought to mitigate suffering within systems of animal use. The second, animal rights , demanded the abolition of that use entirely.

Rights advocates reject all animal farming. From a rights perspective, even the most spacious pasture-based farm involves premature killing, selective breeding for disease-prone growth rates, and separation of mothers from offspring. Francione argues that ‘compassionate carnivorism’ is an oxymoron. Empirical evidence supports this: even high-welfare farms send animals to the same slaughterhouses as factory farms. The rights position thus demands plant-based agriculture as the only consistent ethical response. Welfare regulation in research is extensive: the Animal Welfare Act (US), the EU Directive 2010/63, and the 3Rs principle (Replacement, Reduction, Refinement). Institutional Animal Care and Use Committees (IACUCs) balance potential human benefits against animal suffering. Welfare allows animal use as long as suffering is minimised and alternatives are exhausted.

This paper will: (1) trace the historical and philosophical origins of each movement; (2) articulate their core tenets, including the welfare concept of the ‘Five Freedoms’ and the rights-based rejection of speciesism; (3) compare their applications in three contested arenas (factory farming, biomedical research, and entertainment); (4) explore contemporary points of convergence, such as the recognition of animal sentience; and (5) evaluate the strengths and weaknesses of each approach. The conclusion suggests that a hybrid model—strategic welfare reform alongside long-term rights advocacy—may offer the most effective path forward. 2.1 The Precursors: From Jeremy Bentham to the Anti-Cruelty Movement The modern animal welfare movement owes its philosophical anchor to English utilitarian Jeremy Bentham. In 1789, while critiquing the French concept of natural rights, Bentham famously noted: “The question is not, Can they reason? nor Can they talk? but, Can they suffer?” Bentham did not argue for animal rights in the modern sense, but he established sentience —the capacity to experience pleasure and pain—as the morally relevant criterion. This insight underpins all subsequent welfare thinking.
