A PETA (People for the Ethical Treatment of Animals) demonstration in Seoul, South Korea, against the use of animals for fur in clothing.
Peter Singer argues that humans and animals should receive equal consideration of their interests based on his Principle of Equal Consideration of Interests (PEC). This principle asserts that one must give equal weight in moral decision-making to the like interests of all beings affected by an action.1
Singerās argument rests on the following points:
- Sentience as the Basis for Interests: Singer contends that the capacity to feel pain and experience pleasure is the fundamental condition for having interests. Because both humans and animals are sentient, both have an interest in avoiding pain.12
- Rejection of Speciesism: Singer argues that species membership is a morally irrelevant characteristic, much like race or sex. He defines speciesism as the irrational discrimination against beings based solely on their species, which he views as analogous to racism and sexism.13
- Equality of Interests: He maintains that there is no logical justification for valuing a human's interest in avoiding pain more than a similar interest held by an animal. Therefore, if a being has interests, those interests must be taken into account regardless of the species to which the being belongs.13
Ultimately, Singerās utilitarian framework holds that we have a moral obligation to minimize suffering, and this duty extends to all sentient beings capable of experiencing it.342
