How should we treat animals? Jeremy Bentham argued that we should weigh animal suffering in our moral decision making, and Peter Singer's concept of speciesism is a modern version of that utilitarian approach. Gary L. Francione argues that philosophers like Peter Singer who focus on animal welfare have not gone far enough: what matters is that we shouldn't use animals at all. He calls his approach abolitionism.
