Biological explanation for utilitarianism

It has been suggested that sociobiology, the study of the evolution of human society, provides support for the utilitarian point of view. For example, in The Expanding Circle: Ethics and Sociobiology, the utilitarian philosopher Peter Singer argues that fundamentally utilitarian ethical reasoning has existed from the time primitive foraging bands had to cooperate, compromise, and make group decisions to survive. He elaborates: "In a dispute between members of a cohesive group of reasoning beings, the demand for a reason is a demand for a justification that can be accepted by the group as a whole." Thus, consideration of others' interests has long been a necessary part of the human experience. Singer believes that reason now compels the equal consideration of all people's interests:

:If I have seen that from an ethical point of view I am just one person among the many in my society, and my interests are no more important, from the point of view of the whole, than the similar interests of others within my society, I am ready to see that, from a still larger point of view, my society is just one among other societies, and the interests of members of my society are no more important, from that larger perspective, than the similar interests of members of other societies? Taking the impartial element in ethical reasoning to its logical conclusion means, first, accepting that we ought to have equal concern for all human beings.

This conclusion -- that everybody's interests should be considered equally when making decisions -- is a core tenet of utilitarianism.

Singer elaborates that viewing oneself as equal to others in one's society and at the same time viewing one's society as fundamentally superior to other societies may cause an uncomfortable cognitive dissonance. This is the sense in which he means that reason may push people to accept a broader utilitarian stance. Critics (e.g. Binmore 2005) point out that this cognitive dissonance is apparently not very strong, since people often knowingly ignore the interests of faraway socities quite similar to their own. They also note that the "ought" of the quoted paragraph applies only to someone who has already accepted the premise that all socities are equally important. Singer has responded that his argument in Expanding the Circle wasn't intended to provide a complete philosophical justification for a utilitarian categorical imperative, but merely to provide a plausible explanation for how some people come to accept utilitarianism.
