Singer argues for the principle of equality, which says that equal interests should be treated equally, regardless of the being who has those interests. For example, the interest in avoiding pain and suffering is something that is shared by all sentient life, therefore we should respect that interest in animals. Animals have their own lives and experiences just like us. For them to not even have basic interests such as pleasure and avoiding pain would render them as nothing but autonomous machines.

They do not necessarily disagree with each other’s views, but they focus on separate things. Singer is concerned with animals and how we should think about animal rights, while Mill is mostly concerned with humans and how we should structure society to cultivate happiness and higher pleasures. Mill believes that there are lower pleasures, like pleasures of the senses, and higher pleasures, like the love for philosophical debates. He believes that the only way the achieve true happiness is through higher pleasures, which is
