(Almost) every moral theory can be represented by a utility function

This was demonstrated, in a certain limited way, in Peterson (2009). See also Lowry & Peterson (2011).

The Peterson result provides an "asymmetry argument" in favor of consequentialism:

Consequentialists can account for phenomena that are usually thought of in nonconsequentialist terms, such as rights, duties, and virtues, whereas the opposite is false of nonconsequentialist theories. Rights, duty or virtue-based theories cannot account for the fundamental moral importance of consequences. Because of this asymmetry, it seems it would be preferable to become a consequentialist – indeed, it would be virtually impossible not to be a consequentialist.

Another argument in favor of consequentialism has to do with the causes of different types of moral judgments: see Are Deontological Moral Judgments Rationalizations?

Update: see Carl's criticism.

That's fine as a heuristic for choosing the morally best action, but that's not really what the papers are talking about. They're talking about whether the underlying moral theory is consequentialist or deonotological, not whether the heuristics for finding moral outcomes fall into either category.

Never mind whether it works in practice...does it work in theory?
