  In response, utilitarians can remind critics that the principle of utility is intended as only a criterion of right and not as a decision procedure, so utilitarianism does not imply that people ought to calculate utilities before acting (Railton 1984). Consequentialists can also allow the special perspective of a friend or spouse to be reflected in agent-relative value assessments (Sen 1982, Broome 1991, Portmore 2001, 2003) or probability assessments (Jackson 1991). It remains controversial, however, whether any form of consequentialism can adequately incorporate common moral intuitions about friendship.
