The ethics of animal research

Animal use has been a hotly contested moral issue for hundreds of years. In the 17th century René Descartes, a French philosopher, argued that animals were no more than automata and could not feel pain. This was rejected by Jeremy Bentham in the 18th Century who extended his utilitarian conception of rights to animals due to their capability to suffer. This was expanded by Peter Singer, in 1975, who wrote in Animal Liberation that arbitrarily treating humans above animals – particularly in marginal cases where animals may be as intelligent as young children or severely cognitively-impaired adults – was not justified.

Animal rights philosophy is distinct from proponents of animal welfare who argue that we must provide adequate conditions for animals in our care – a position held by the RSPCA among others. The scientific community has often been the driving force for these improvements, arguing that better conditions for animals was conducive to better, more replicable, scientific results.


Animal Liberation (Peter Singer) was an immensely influential book which discussed the ethics of animal use (including animal research). It is often considered the forerunner to the animal liberation movement. This is, perhaps, the core piece of literature on  animal rights philosophy.

Do Animals Have Rights? (Alison Hills) is an objective assessment of the case for whether animals should have rights and what rights those should be. Hills discusses their ability of mind, whether all animals should be regarded as equal, and what that means. Hills concludes with a graded scale of animals rights.

The Case for Animal Rights (Tom Reagan) is another major piece of philosophical writing which argues for animal rights on the basis of their similar cognitive abilities.

A Rat is a Pig is a Dog is a Boy (Wesley J Smith) takes its title from a quote from PETA president, Ingrid Newkirk. It is a useful book covering many issues of animal rights activism and philosophy. In Chapter 18, Smith creates his argument in favour of animal research on the basis of human rights and duties.

The Human Use of Animals: Case Studies in Ethical Choice (Beauchamp et al.) investigates a number of difficult issues regarding the use of animals in society. Through 16 case studies, and plenty of ethical theory, the authors attempt to navigate the moral minefields involved.

An Odyssey with Animals (Adrian Morrison) investigates the relationship between humans and animals, and explains why efforts to halt animal research would be damaging to human health.
