Chapter 12 endnote 7, from Lisa Feldman Barrett.
Some context is:
The eighteenth-century philosopher Jeremy Bentham thought that an animal belongs in the human moral circle only if we can prove the animal can feel pleasure or pain. [...] Bentham believed in utilitarianism.
Jeremy Bentham believed that the morality of an action is determined by its outcome; specifically, by its utility to cause pleasure or happiness to sentient creatures. This belief is called utilitarianism. Because non-human animals can suffer, their happiness is part of this equation.
